Non-invasive eye tracking technology based on corneal reflex
Published 2012-12-01“…For the deficiencies that existing eye tracking devices are complex,have too many restrictions on the position,need to wear special equipment.A novel method of eye tracking technology using the five near-infrared light as the source of corneal reflex was put forward.This method did not need any wearing equipment,and could adapt to the natural head movement,the algorithm designed calculates the position of sight in high accuracy.A novel method of pupil edge fitting was put forward:fitted circularly and removed false points to get accurate position of pupil center,improved mapping accuracy.Used the GrayScale of image to initialize eye position quickly and accurately.Using the theory of cross-ratio invariance to make coordinate mapping,finally calculated the attention coordinate accurately.…”

Video steganalysis scheme based on weighted undirected graph
Published 2014-10-01“…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.…”

Method of anti-confusion texture feature descriptor for malware images
Published 2018-11-01“…It is a new method that uses image processing and machine learning algorithms to classify malware samples in malware visualization field.The texture feature description method has great influence on the result.To solve this problem,a new method was presented that joints global feature of GIST with local features of LBP or dense SIFT in order to construct combinative descriptors of malware gray-scale images.Using those descriptors,the malware classification performance was greatly improved in contrast to traditional method,especially for those samples have higher similarity in the different families,or those have lower similarity in the same family.A lot of experiments show that new method is much more effective and general than traditional method.On the confusing dataset,the accuracy rate of classification has been greatly improved.…”

Simple constellation shaping for BICM-ID
Published 2015-06-01“…A novel method of constellation mapping is presented for bit-interleaved coded modulation (BICM) by combining geometry shaping with probabilistic shaping.The transmitted signal points of a practical signal constellation approach the optimal input distribution by exploiting a many-to-one mapping with some signal points unused.With this method,shaping gain can be achieved conveniently with the help of iterative decoding between demodulation and decoder.The optimizations of signal constellation and the mapping from symbols to signal points are performed by the analysis of capacity and the extrinsic information transfer chart.Simulation results show that the proposed constellation mapping outperforms the traditional Gray mapping for BICM with iterative decoding in both AWGN and Rayleigh channels.And the shaping gain achieved can be improved with the increase of the constellation size.…”
