It then describes key aspects of image and video deduplication, including extracting fingerprints from images and frames to identify duplicates.

Deepfake detection is a critical and evolving field aimed at identifying and mitigating the risks associated with manipulated multimedia content created using artificial intelligence (AI) techniques. Deepfakes involve the use of advanced machine learning algorithms, particularly generative models like Generative Adversarial Networks (GANs), to create highly convincing fake videos, audio recordings, or images that can deceive viewers into believing they are genuine.
One prevalent approach to deepfake detection involves leveraging advancements in computer vision and pattern recognition. Researchers and developers employ sophisticated algorithms to analyze various visual and auditory cues that may indicate the presence of deepfake manipulation. For instance, anomalies in facial expressions, inconsistent lighting and shadows, or unnatural lip sync in videos can be indicative of deepfake content. Additionally, deepfake detectors may examine metadata, such as inconsistencies in timestamps or editing artifacts, to identify alterations in the content's authenticity.
Machine learning plays a central role in deepfake detection, with models being trained on diverse datasets that include both authentic and manipulated content. Supervised learning techniques involve training models on labeled datasets, enabling them to recognize patterns associated with deepfake manipulation. Researchers also explore unsupervised and semi-supervised learning methods, allowing detectors to identify anomalies without explicit labels for every training instance.
As the field progresses, deepfake detectors are increasingly adopting advanced neural network architectures to enhance their accuracy. Ensembling multiple models, each specialized in detecting specific types of manipulations, is another strategy employed to improve overall detection performance. Furthermore, the integration of explainable AI techniques enables better understanding of the detection process and provides insights into the features contributing to the decision-making process of the models.
Despite these advancements, deepfake detection remains a challenging task due to the constant evolution of deepfake generation techniques. Adversarial training, where detectors are trained on data that includes adversarial examples, is one method to improve robustness against sophisticated manipulation attempts. Continuous research efforts are required to stay ahead of emerging deepfake technologies and to develop detectors capable of identifying novel manipulation methods.
In conclusion, deepfake detection is a multidimensional challenge that requires a combination of computer vision, machine learning, and data analysis techniques. Researchers and practitioners are actively developing and refining methods to detect manipulated content by examining visual and auditory cues, leveraging machine learning models, and staying vigilant against evolving deepfake technologies.

The document summarizes two video watermarking algorithms that use Singular Value Decomposition (SVD). The first algorithm embeds watermark bits diagonally in the SVD-transformed U, S, or V matrices of video frames. The second algorithm embeds bits in blocks of the U or V matrices. Both algorithms were evaluated based on imperceptibility, robustness, and data payload. The diagonal embedding achieved better robustness while the block-wise embedding had a higher data payload rate. SVD transforms video frames, distributing the watermark across spatial and frequency domains for improved imperceptibility and robustness against attacks.

Fast discrimination of fake video manipulationIJECEIAES
Deepfakes have become possible using artificial intelligence techniques, replacing one person’s face with another person’s face (primarily a public figure), making the latter do or say things he would not have done. Therefore, contributing to a solution for video credibility has become a critical goal that we will address in this paper. Our work exploits the visible artifacts (blur inconsistencies) which are generated by the manipulation process. We analyze focus quality and its ability to detect these artifacts. Focus measure operators in this paper include image Laplacian and image gradient groups, which are very fast to compute and do not need a large dataset for training. The results showed that i) the Laplacian group operators, as a value, may be lower or higher in the fake video than its value in the real video, depending on the quality of the fake video, so we cannot use them for deepfake detection and ii) the gradient-based measure (GRA7) decreases its value in the fake video in all cases, whether the fake video is of high or low quality and can help detect deepfake.
IRJET- Transformation of Realistic Images and Videos into Cartoon Images and ...IRJET Journal
This document summarizes research on using a Generative Adversarial Network (GAN) called Cartoon GAN to transform real-world images and videos into cartoon images and videos.

They were able to successfully convert both individual images and video clips into cartoon/animated versions. For video, they used the OpenCV library to divide videos into frames, pass each frame through the trained Cartoon GAN model, and then recombine the cartoonized frames into an output cartoon video. The researchers concluded that Cartoon GAN is an effective method for automatically transforming real media into cartoons and aims to improve the quality and resolution
This technique detects inter-frame forgery in videos by analyzing prediction residual gradient (PRG) and optical flow gradient (OFG) between frames. It first extracts I and P frames and computes PRG and OFG. Thresholds are applied to identify spikes in these features indicating possible tampering. Original and forged videos are distinguished by checking for discontinuities or continuities in spike patterns. The technique was found to detect tampering with 90% accuracy regardless of video codec, recording device, bitrate, or number of tampered frames.

The system architecture involves preprocessing, feature detection/tracking, motion estimation, trajectory smoothing, stabilization, and output. Results on sample videos demonstrate reduced shakiness before and after stabilization.
1. Previous work on green screen keying required controlled illumination and manual guidance, which is not feasible for real-time applications.
2. Recent approaches have used deep learning models but these struggle to achieve both high robustness and pixel-wise accuracy.
3. The proposed method in the paper uses a deeply guided linear model that first performs segmentation using a robust CNN, then applies a linear model to refine the segmentation, achieving both high robustness and accuracy for real-time green screen keying without specialized lighting or manual input.
The proposed scheme embedded the watermark during the differential pulse code modulation process and extracted through decoding the entropy details. This technique utilize the moving picture expert groups standard (MPEG-2) in which discrete cosine transform coefficients are adjusted from selected instantaneous decoder refresh frames for watermarking purpose. The subsets of frames as candidate I-frames are chosen to achieve better perceptibility and robustness. A secret key based cryptographic technique is used to select the candidate frames. Three more keys are required to extract the watermark whereas one of the key is used to stop the extraction process and the remaining two are used to display the scrambled watermark. The toughness is evaluated by testing spatial and temporal synchronization attacks. High sturdiness is achieved against video specific attacks frequently occurs in the real world. Even a single frame can accommodate thousand of watermark bits which reflect that high watermark capacity can be obtained.
PERFORMANCE ANALYSIS OF FINGERPRINTING EXTRACTION ALGORITHM IN VIDEO COPY DET...IJCSEIT Journal
A video fingerprint is a recognizer that is derived from a piece of video content. The video fingerprinting
methods obtain unique features of a video that differentiates one video clip from another. It aims to identify
whether a query video segment is a copy of video from the video database or not based on the signature of
the video. It is difficult to find whether a video is a copied video or a similar video, since the features of the
content are very similar from one video to the other. The main focus of this paper is to detect that the query
video is present in the video database with robustness depending on the content of video and also by fast
search of fingerprints. The Fingerprint Extraction Algorithm and Fast Search Algorithms are adopted in
this paper to achieve robust, fast, efficient and accurate video copy detection. As a first step, the
Fingerprint Extraction algorithm is employed which extracts a fingerprint through the features from the
image content of video. The images are represented as Temporally Informative Representative Images
(TIRI). Then, the second step is to find the presence of copy of a query video in a video database, in which
a close match of its fingerprint in the corresponding fingerprint database is searched using inverted-filebased
method. The proposed system is tested against various attacks like noise, brightness, contrast,
rotation and frame drop. Thus the performance of the proposed system on an average shows high true
positive rate of 98% and low false positive rate of 1.3% for different attacks.

Video content analysis and retrieval system using video storytelling and inde...IJECEIAES
Videos are used often for communicating ideas, concepts, experience, and situations, because of the significant advances made in video communication technology. The social media platforms enhanced the video usage expeditiously. At, present, recognition of a video is done, using the metadata like video title, video descriptions, and video thumbnails. There are situations like video searcher requires only a video clip on a specific topic from a long video. This paper proposes a novel methodology for the analysis of video content and using video storytelling and indexing techniques for the retrieval of the intended video clip from a long duration video. Video storytelling technique is used for video content analysis and to produce a description of the video. The video description thus created is used for preparation of an index using wormhole algorithm, guarantying the search of a keyword of definite length L, within the minimum worst-case time. This video index can be used by video searching algorithm to retrieve the relevant part of the video by virtue of the frequency of the word in the keyword search of the video index. Instead of downloading and transferring a whole video, the user can download or transfer the specifically necessary video clip. The network constraints associated with the transfer of videos are considerably addressed.
Multimodal Biometrics Recognition from Facial Video via Deep Learning cscpconf
Biometrics identification using multiple modalities has attracted the attention of many
researchers as it produces more robust and trustworthy results than single modality biometrics.
In this paper, we present a novel multimodal recognition system that trains a Deep Learning
Network to automatically learn features after extracting multiple biometric modalities from a
single data source, i.e., facial video clips. Utilizing different modalities, i.e., left ear, left profile
face, frontal face, right profile face, and right ear, present in the facial video clips, we train
supervised denosing autoencoders to automatically extract robust and non-redundant features.
The automatically learned features are then used to train modality specific sparse classifiers to
perform the multimodal recognition. Experiments conducted on the constrained facial video
dataset (WVU) and the unconstrained facial video dataset (HONDA/UCSD), resulted in a
99.17% and 97.14% rank-1 recognition rates, respectively. The multimodal recognition
accuracy demonstrates the superiority and robustness of the proposed approach irrespective of
the illumination, non-planar movement, and pose variations present in the video clips.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

The toughness is evaluated by testing spatial and temporal synchronization attacks. High sturdiness is achieved against video specific attacks frequently occurs in the real world. Even a single frame can accommodate thousand of watermark bits which reflect that high watermark capacity can be obtained.
PERFORMANCE ANALYSIS OF FINGERPRINTING EXTRACTION ALGORITHM IN VIDEO COPY DET...IJCSEIT Journal
A video fingerprint is a recognizer that is derived from a piece of video content. The video fingerprinting
methods obtain unique features of a video that differentiates one video clip from another. It aims to identify
whether a query video segment is a copy of video from the video database or not based on the signature of
the video. It is difficult to find whether a video is a copied video or a similar video, since the features of the
content are very similar from one video to the other. The main focus of this paper is to detect that the query
video is present in the video database with robustness depending on the content of video and also by fast
search of fingerprints. The Fingerprint Extraction Algorithm and Fast Search Algorithms are adopted in
this paper to achieve robust, fast, efficient and accurate video copy detection. As a first step, the
Fingerprint Extraction algorithm is employed which extracts a fingerprint through the features from the
image content of video. The images are represented as Temporally Informative Representative Images
(TIRI). Then, the second step is to find the presence of copy of a query video in a video database, in which
a close match of its fingerprint in the corresponding fingerprint database is searched using inverted-filebased
method. The proposed system is tested against various attacks like noise, brightness, contrast,
rotation and frame drop. Thus the performance of the proposed system on an average shows high true
positive rate of 98% and low false positive rate of 1.3% for different attacks.

Video content analysis and retrieval system using video storytelling and inde...IJECEIAES
Videos are used often for communicating ideas, concepts, experience, and situations, because of the significant advances made in video communication technology. The social media platforms enhanced the video usage expeditiously. At, present, recognition of a video is done, using the metadata like video title, video descriptions, and video thumbnails. There are situations like video searcher requires only a video clip on a specific topic from a long video. This paper proposes a novel methodology for the analysis of video content and using video storytelling and indexing techniques for the retrieval of the intended video clip from a long duration video. Video storytelling technique is used for video content analysis and to produce a description of the video. The video description thus created is used for preparation of an index using wormhole algorithm, guarantying the search of a keyword of definite length L, within the minimum worst-case time. This video index can be used by video searching algorithm to retrieve the relevant part of the video by virtue of the frequency of the word in the keyword search of the video index. Instead of downloading and transferring a whole video, the user can download or transfer the specifically necessary video clip. The network constraints associated with the transfer of videos are considerably addressed.
Multimodal Biometrics Recognition from Facial Video via Deep Learning cscpconf
Biometrics identification using multiple modalities has attracted the attention of many
researchers as it produces more robust and trustworthy results than single modality biometrics.
In this paper, we present a novel multimodal recognition system that trains a Deep Learning
Network to automatically learn features after extracting multiple biometric modalities from a
single data source, i.e., facial video clips. Utilizing different modalities, i.e., left ear, left profile
face, frontal face, right profile face, and right ear, present in the facial video clips, we train
supervised denosing autoencoders to automatically extract robust and non-redundant features.
The automatically learned features are then used to train modality specific sparse classifiers to
perform the multimodal recognition. Experiments conducted on the constrained facial video
dataset (WVU) and the unconstrained facial video dataset (HONDA/UCSD), resulted in a
99.17% and 97.14% rank-1 recognition rates, respectively. The multimodal recognition
accuracy demonstrates the superiority and robustness of the proposed approach irrespective of
the illumination, non-planar movement, and pose variations present in the video clips.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEMHODECEDSIET
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
