Using image stitching and image steganography security can be provided to any image which has to be
sent over the network or transferred using any electronic mode. There is a message and a secret image that
has to be sent. The secret image is divided into parts.The first phase is the Encrypting Phase, which deals
with the process of converting the actual secret message into ciphertext using the AES algorithm. In the
second phase which is the Embedding Phase, the cipher text is embedded into any part of the secret image
that is to be sent. Third phase is the Hiding Phase, where steganography is performed on the output image
of Embedding Phase and other parts of the image where the parts are camouflaged by another image using
least significant bit replacement. These individual parts are sent to the concerned receiver. At the
receivers end decryption of Hiding phase and Embedding Phase takes place respectively. The parts
obtained are stitched together using k nearest method. Using SIFT features the quality of the image is
improved.

Design of algorithm for detection of hidden objects from Tera hertz imagesIOSR Journals
This document presents an algorithm for detecting hidden objects in terahertz images using a three-stage approach. The first stage applies edge-based segmentation after smoothing the image. The second stage extracts shape descriptors like Gabor and GLCM texture features from regions of interest. Finally, a Euclidean distance criterion is used to classify objects by comparing a test feature vector to vectors in a database. The algorithm was tested on gun, knife and needle images, achieving a 1.04% detection error rate and 91.9% detection rate compared to ground truths. Potential applications are in security screening to detect weapons and explosives in public areas.

concealed weapon detection using digital image processingKongara Sudharshan
This document proposes and describes a method for concealed weapon detection using digital image processing. The method uses both a visual RGB image and an infrared image as inputs. It resizes the images, complements the infrared image, and performs discrete wavelet transform fusion on the images. The fused image is converted to grayscale and binarized before weapon detection is attempted. Challenges include performing accurate detection from a distance while minimizing false alarms. More research is needed to improve detection when clothing is loose.

This document discusses jump instructions in PLC ladder logic. Jump instructions allow a PLC program to break its normal sequential execution and move to another part of the program. The key points covered are:
- Jump instructions work with label instructions to redirect program flow. The jump instruction moves execution to the rung with a matching label number.
- Jumps can move execution forward or backward within a program. Multiple jumps can target the same label. Jumps can also be nested within other jumps.
- Advantages of jumps include allowing a PLC to run multiple programs, jumping sections during faults to reduce downtime, and improving scan time performance.
- An example is provided demonstrating a parking lot control system

Rainfall intensity duration frequency curve statistical analysis and modeling...bijceesjournal
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.
