Object detection is a main role in image processing.the proposed methods detect various multiple object detection using image processing so provide a really to solving the security problem.
Object detection is a computer technology related to computer vision and image processing that deals with detecting instances of semantic objects of a certain class (such as humans, buildings, or cars) in digital images and videos. Well-researched domains of object detection include face detection and pedestrian detection. Object detection has applications in many areas of computer vision, including image retrieval and video surveillance.
This document discusses object detection using the Single Shot Detector (SSD) algorithm with the MobileNet V1 architecture. It begins with an introduction to object detection and a literature review of common techniques. It then describes the basic architecture of convolutional neural networks and how they are used for feature extraction in SSD. The SSD framework uses multi-scale feature maps for detection and convolutional predictors. MobileNet V1 reduces model size and complexity through depthwise separable convolutions. This allows SSD with MobileNet V1 to perform real-time object detection with reduced parameters and computations compared to other models.
The KLT tracker is a classic algorithm for visual object tracking published in 1981. It works by tracking feature points between consecutive video frames using the Lucas-Kanade optical flow method. The KLT tracker is still widely used due to its computational efficiency and availability in many computer vision libraries. However, it is best suited for tracking textured objects and may struggle with uniform textures or large displacements between frames.
Multiple object tracking (MOT) involves localizing and identifying multiple moving objects over time using video input. MOT has various applications including human-computer interaction, surveillance, and medical imaging. It allows too many detected objects to be matched across frames and tracks objects even if detection fails in some frames. However, challenges include implementing real-time tracking due to batch-based algorithms and solving identity switches and fragmentation when detections are missed. Common MOT methods include Faster R-CNN for detection, Kalman filters for prediction, CNNs for appearance features, and the Hungarian algorithm for data association and tracking.
[PR12] You Only Look Once (YOLO): Unified Real-Time Object DetectionTaegyun Jeon
The document summarizes the You Only Look Once (YOLO) object detection method. YOLO frames object detection as a single regression problem to directly predict bounding boxes and class probabilities from full images in one pass. This allows for extremely fast detection speeds of 45 frames per second. YOLO uses a feedforward convolutional neural network to apply a single neural network to the full image. This allows it to leverage contextual information and makes predictions about bounding boxes and class probabilities for all classes with one network.
Tracking is the problem of estimating the trajectory of an object as it moves around a scene. Motion tracking involves collecting data on human movement using sensors to control outputs like music or lighting based on performer actions. Motion tracking differs from motion capture in that it requires less equipment, is less expensive, and is concerned with qualities of motion rather than highly accurate data collection. Optical flow estimates the pixel-wise motion between frames in a video by calculating velocity vectors for each pixel.
Multi-object tracking is a computer vision task which can track objects belonging to different categories, such as cars, pedestrians and animals by analyzing the videos.
This document discusses and compares different methods for deep learning object detection, including region proposal-based methods like R-CNN, Fast R-CNN, Faster R-CNN, and Mask R-CNN as well as single shot methods like YOLO, YOLOv2, and SSD. Region proposal-based methods tend to have higher accuracy but are slower, while single shot methods are faster but less accurate. Newer methods like Faster R-CNN, R-FCN, YOLOv2, and SSD have improved speed and accuracy over earlier approaches.
Object detection is an important computer vision technique with applications in several domains such as autonomous driving, personal and industrial robotics. The below slides cover the history of object detection from before deep learning until recent research. The slides aim to cover the history and future directions of object detection, as well as some guidelines for how to choose which type of object detector to use for your own project.
Faster R-CNN improves object detection by introducing a Region Proposal Network (RPN) that shares full-image convolutional features with the detection network, thus enabling nearly cost-free region proposals. The RPN slides over feature maps and predicts object bounds and objectness at each position. During training, anchors are assigned positive or negative labels based on Intersection over Union with ground truth boxes. Faster R-CNN runs the RPN in parallel with Fast R-CNN for detection, end-to-end in a single network and stage. This achieves state-of-the-art object detection speed and accuracy while eliminating computationally expensive selective search for proposals.
PR-207: YOLOv3: An Incremental ImprovementJinwon Lee
YOLOv3 makes the following incremental improvements over previous versions of YOLO:
1. It predicts bounding boxes at three different scales to detect objects more accurately at a variety of sizes.
2. It uses Darknet-53 as its feature extractor, which provides better performance than ResNet while being faster to evaluate.
3. It predicts more bounding boxes overall (over 10,000) to detect objects more precisely, as compared to YOLOv2 which predicts around 800 boxes.
YOLO (You Only Look Once) is a real-time object detection system that frames object detection as a regression problem. It uses a single neural network that predicts bounding boxes and class probabilities directly from full images in one evaluation. This approach allows YOLO to process images and perform object detection over 45 frames per second while maintaining high accuracy compared to previous systems. YOLO was trained on natural images from PASCAL VOC and can generalize to new domains like artwork without significant degradation in performance, unlike other methods that struggle with domain shift.
Deep learning based object detection basicsBrodmann17
The document discusses different approaches to object detection in images using deep learning. It begins with describing detection as classification, where an image is classified into categories for what objects are present. It then discusses approaches that involve separating detection into a classification head and localization head. The document also covers improvements like R-CNN which uses region proposals to first generate candidate object regions before running classification and bounding box regression on those regions using CNN features. This helps address issues with previous approaches like being too slow when running the CNN over the entire image at multiple locations and scales.
GTSRB Traffic Sign recognition using machine learningRupali Aher
This document discusses traffic sign detection and classification. It outlines challenges like variable visual appearances and conditions. The goal is high accuracy recognition in real worlds. It explores feature extraction methods like raw pixels, color histograms, and HOG. Classification algorithms tested include MLP, KNN, SVM, random forest, and CNN using the German Traffic Sign Recognition Benchmark dataset. HOG performed best, and MLP achieved highest accuracy at 98%. The conclusion is HOG is most efficient for extraction and MLP performs best for classification.
YOLOv4: optimal speed and accuracy of object detection reviewLEE HOSEONG
YOLOv4 builds upon previous YOLO models and introduces techniques like CSPDarknet53, SPP, PAN, Mosaic data augmentation, and modifications to existing methods to achieve state-of-the-art object detection speed and accuracy while being trainable on a single GPU. Experiments show that combining these techniques through a "bag of freebies" and "bag of specials" approach improves classifier and detector performance over baselines on standard datasets. The paper contributes an efficient object detection model suitable for production use with limited resources.
Overview Of Video Object Tracking SystemEditor IJMTER
The goal of video object tracking system is segmenting a region of interest from a video
scene and keeping track of its motion, positioning and occlusion. There are the three steps of video
object tracking system those are object detection, object classification and object tracking. Object
detection is performed to check existence of objects in video. Then the detected object can be
classified in various categories on the basis on their shape, motion, color and texture. Object tracking
is performed using monitoring object changes. This paper we are going to take overview of different
object detection, object classification and object tracking techniques and also the comparison of
different techniques used for various stages of tracking.

The document discusses e-call systems, which automatically connect to emergency services in the event of a vehicle accident. E-call systems use in-vehicle sensors to detect accidents and GPS to locate the vehicle. They then make an emergency 112 voice call and transmit a minimum set of data about the time, location, and vehicle. This allows emergency responders to arrive faster, which can save thousands of lives each year by reducing the time between an accident and medical assistance. The technology is complex but becoming mandatory in new European vehicles by 2015 due to its life-saving benefits.
eCall, the European system for rapid assistance to motorists involved in a collision, will soon be a reality. Learn how it works and how it will affect you. Presentation given by Dr David Williams (Chairman of ETSI EMTEL), from Qualcomm, to the IET Swindon Local Network, 10th Feb 2015.
This document discusses e-call, an emergency system in vehicles that automatically contacts emergency services in the event of a crash. It reduces response time from 30 minutes to within minutes by using sensors to detect crashes and GPS to pinpoint the location. The system sends data to a public safety access point that then alerts rescue services. Standards and technology ensure reliable communication between vehicles and emergency centers. E-call is currently installed by some automakers and will be mandatory in new European vehicles by 2015 to save lives by hastening medical response.
This document summarizes an article that reviews object tracking methods. It categorizes tracking approaches based on the object and motion representations used.

Glas Trösch - Challenges of using glass in the Alpine regionsBenjamin Schulz
High up in the Alps, the architecture is often characterized by a traditional method of construction that has few transparent surfaces and, in order to provide protection against the extreme weather conditions, tends to be of rather reserved nature. This is where contemporary façade glazing opens up new opportunities: The transparent material not only offers greater creative freedom but also enables designers to realise bright and inviting rooms which allow for far-reaching views of the mountains and create the optimum conditions for the successful use of the buildings from the tourism aspect. As a Swiss company, Glas Trösch has extensive experience in the use of glass at extreme altitudes and knows the special requirements demanded of the material at these exposed locations.
The document proposes a novel approach to simulate mouse functions using only a webcam and computer vision techniques. Two colored tapes would be worn on the fingers to detect hand gestures for controlling mouse movements and clicks. The yellow tape on the index finger would control cursor position while the distance between the yellow and red tapes would determine click events. Left clicks would occur when the thumb tape nears the index finger tape, right clicks from pausing in position, and double clicks from pausing both tapes in position. This vision-based mouse simulation could revolutionize human-computer interaction by eliminating physical devices.
In this presentation we describe the formulation of the HMM model as consisting of states that are hidden that generate the observables. We introduce the 3 basic problems: Finding the probability of a sequence of observation given the model, the decoding problem of finding the hidden states given the observations and the model and the training problem of determining the model parameters that generate the given observations. We discuss the Forward, Backward, Viterbi and Forward-Backward algorithms.
This document provides an overview of speech recognition technology. It defines speech recognition as the ability to translate spoken words to text. The key components of a speech recognition system include an audio input, grammar, speech recognition engine, acoustic model, and recognized text output. The speech recognition engine uses the acoustic model and grammar to analyze the audio input and return recognized text. Applications of speech recognition include dictation, data entry, and assisting individuals with disabilities. While speech recognition technology has advanced, challenges remain around digitization of speech, signal processing, and accurately recognizing different speakers. The future of assistive technology using speech recognition in education looks promising.
Optical Lithography, Key Enabling Technology for our Modern WorldReinhard Voelkel
In 1959, Richard P. Feynman initiated the Nano-age in his lecture “There’s plenty of room at the bottom”. Feynman also had a clear vision about computers and asked: ”Why can’t we make them very small, make them of little wires, little elements - and by little, I mean little. For instance, the wires should be 10 or 100 atoms in diameter, and the circuits should be a few thousand angstroms across.”
At the same time, Jean Hoerni from Fairchild Semiconductors tried to get his “planar process” to production. Hoerni’s planar process using silicon substrates, so-called “wafers”, revolutionized semiconductor manufacturing and was widely adapted by the industry. The great success of the planar wafer process is also much related with tremendous improvements in optical lithography over all the years. From the early age dominated by mask aligners to highly sophisticated steppers and scanners, lithography was the key enabling technology, allowing now – 50 years after Feynman’s vision – nanostructuring down to the atomic scale on 300mm planar wafers. The evolutionary development of optical lithography is reviewed along with a brief discussion of options for the future.
Traffic demand management aims to reduce single-occupancy vehicle travel and redistribute travel demand. Managing traffic demand at junctions is important to reduce accidents, pollution, wasted time and money, and improve public transportation options. Several methods can be used for traffic demand management at junctions, including traffic surveys, educating the public, enforcing traffic laws, improving junction infrastructure with signs, flyovers, traffic lights, and pedestrian crossings, implementing bicycle infrastructure, congestion pricing, active traffic management, and integrated demand management. Case studies demonstrate how these strategies can be applied using existing traffic control systems.
The document provides an overview of the main concepts in speech recognition systems, including the lexicon, acoustic model, language model, and WFST decoder. It explains that the lexicon maps words to phone sequences, the acoustic model identifies pronunciations from audio features using deep neural networks, and the language model provides word probability distributions. It describes how the WFST decoder integrates these components by decoding speech as a path through a weighted finite state transducer to arrive at the most likely transcription.
This seminar discusses implementing an eCall-compliant early crash notification service for portable and nomadic devices. It presents the architecture and standardization of eCall systems, which use sensors and wireless connectivity to automatically detect vehicle crashes and send critical data like location to emergency services. The document outlines an experimental implementation using an accelerometer crash sensor, eCall box, Bluetooth, and transmission of a minimum data set. Analysis suggests such systems could reduce emergency response times and save lives.
This document provides an overview of colour theory and models for application in multimedia. It describes how colour is perceived and named, then covers the RGB, CMYK, and HSV colour models. It discusses additive and subtractive colour synthesis. The document also addresses colour palettes, web colours, and colour wheels. Colour matching between RGB and CMYK is examined along with references for further information.
Image recognition is a problem that clearly illustrates the advantages of machine learning over traditional programming approaches. In this deep dive, how to quickly get set up with TensorFlow on Ubuntu using containers will be shown. To be even more efficient, what is becoming known as transfer learning will be demonstrated. An existing image recognition model will be used rather than the time consuming approach of building one from scratch. Subsequently, this classifier model will be trained with an image dataset. And finally, the retrained model will be tested with new external images.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

15. Kalman Filter
❏ Kernel based estimation algorithm
❏ Uses 3 position matrix
1. Previous Position
2. Current Position
3. Predicted Position
❏ Updates all of them continuously
Predicted = K × Current + (K-1) × Previous
K = Kalman Filter Gain

18. Multi-Object Tracking
August 04, 2015
Why do we need Multi-Object Tracking?
❏ Real world has more Objects to track at a
time (i.e. a highway)
❏ CamShift or Kalman Filter cannot handle
Multi-Object Tracking alone
❏ Noise and unwanted Object makes tracking
more challenging
❏ A new system needs to be implemented
