Video steganalysis scheme based on weighted undirected graph by Ting DA, Zhi-tang LI

“…A new steganalysis scheme based on taking the inter-frame correlation as the undirected graph weights was proposed utilizing the temporal correlation among video frames.First,getting the eigenvector of every video frame brightness by calculating its gray-level co-occurrence matrix,the eigenvector is an eight-dimensional vector.Then,computing the weights of each video frame by using the euclide distance algorithm.The weighted undirected graph which representing the correlations between each frame is constructed.Finally,according to the change of correlations between the frames after embedding information determine whether the video is embedded confidential information.Experimental results show that the method using weighted undirected graph can quickly discriminate stego video and the original video,and have a high accuracy rate.…”

Robust tampering detection and localization of composite image by Xiao WANG, Rong ZHANG, Lijun GUO

“…Aiming at the problem of tamper detection of composite image of natural images and highly simulated computer-generated images,a method of extracting image block color and texture feature based on differential histogram and local binary texture descriptor in YCbCr color space was proposed.By training posterior probability support vector machine,the image block to be measured was identified.In the case of non-overlapping block,the approximate tampering area was general judged,then the block was discriminated by pixel in the region,ultimately the accurate location of tampering area was achieved.The experimental results show that the recognition rate of 128 dpi×128 dpi image blocks is 94.75%,which is higher than other methods.The tapering region of the synthesized image can be precisely positioned,and the rotation and scaling operation show good coercivity.…”

Retina-imitation sampling based binary descriptor by Qingsheng YUAN, Guoqing JIN, Dongming ZHANG, Xiuguo BAO

“…The existing binary descriptors，generated from random or uniform point pairs sampling，suffer from low robustness and high computation.A novel sampling method,named RBS (retina-imitation based sampling),was proposed， which combines different densities sampling,multi-scale smoothing and reception field overlapping to imitate the converting from light signal to vision of ganglion cells of human retina cells,and further selects most discriminative comparison pairs based on learning on training data.Finally，compact binary descriptor was generated based on comparisons between the neighbor mean instead of singe sampled point.The experimental results show the RBS-128 with 128 bit outperforms FREAK and BRSIK with 512 bit about 16.4% and 5.3% in precision on the dataset provided by Mikolajczyk.…”

Distress, coping and emotional health during the gradual opening of university systems, post COVID19, in India by Shilpa Ashok Pandit, Amit A. Nanavati, Bijal Mehta, Sonal Yadav

“…Survey results show that overall students’ adjustment was significantly influenced by their personal strengths and ability to manage academic challenges after controlling for other factors. Discriminant Function Analysis (DFA) and Binary Logistic Regression Analysis revealed that the key differentiator between the distressed group and others was whether the student reported their ability to share feelings with family members. …”
