Food recognition via an efficient neural network with transformer grouping

Guorui Sheng, Shuqi Sun, Chengxu Liu, Yancun Yang

International Journal of Intelligent Systems > 37 > 12 > 11465 - 11481

Recently, considerable research efforts have been devoted to food recognition for its great potential applications in human health. Much work so far has focused on directly extracted deep visual features via Convolutional Neural Networks, which require significant computational resources and training time. The high requirements on hardware resources severely limit the application of food recognition...

Detection of content-aware image resizing based on Benford’s law

Guorui Sheng, Tao Li, Qingtang Su, Beijing Chen, more

Soft Computing > 2017 > 21 > 19 > 5693-5701

Content-aware image resizing is currently widely used because it maintains the original appearance of important objects to the greatest extent when the aspect ratio of an image changes during resizing. Content-aware image resizing techniques, such as seam carving, are also used for image forgery. A new Benford’s law-based algorithm for detecting content-aware resized images is presented. The algorithm...

Erasing the JPEG Compression Artifacts: An Improved Counter-Forensic Algorithm Based on Parameter Adjustment

Guorui Sheng, Qingtang Su

2014 Ninth International Conference on Broadband and Wireless Computing, Communication and Applications > 321 - 324

2014 Ninth International Conference on Broadband and Wireless Computing, Communication and Applications (BWCCA)

With the growing awareness of the fraud case for digital images, the researchers have developed some forensic techniques that based on the intrinsic statistical history or trace left by the JPEG compression to determine an image's manipulation. In this letter, we present an improved counter-forensic scheme that based on parameter adjustment. The simulation shows that by using the proposed strategy...

A New Anti‐forensic Scheme—Hiding the Single JPEG Compression Trace for Digital Image

Yanjun Cao, Tiegang Gao, Guorui Sheng, Li Fan, more

Journal of Forensic Sciences > 60 > 1 > 197 - 205

To prevent image forgeries, a number of forensic techniques for digital image have been developed that can detect an image's origin, trace its processing history, and can also locate the position of tampering. Especially, the statistical footprint left by JPEG compression operation can be a valuable source of information for the forensic analyst, and some image forensic algorithm have been raised...

A blind color image watermarking based on DC component in the spatial domain

Qingtang Su, Yugang Niu, Qingjun Wang, Guorui Sheng

Optik - International Journal for Light and Electron Optics > 2013 > 124 > 23 > 6255-6260

Color image watermarking has become essential and important copyright protection or authentication scheme. It is noted that most of the existing color image watermarking algorithms are performed only in the single domain (spatial domain or frequency domain), and not to integrate these merits of the different domains. By utilizing the generating principle and distribution feature of the direct current...

A new reversible watermarking scheme based on Integer DCT for medical images

Lin Gao, Tiegang Gao, Guorui Sheng, Yanjun Cao, more

2012 International Conference on Wavelet Analysis and Pattern Recognition > 33 - 37

2012 International Conference on Wavelet Analysis and Pattern Recognition (ICWAPR)

Reversible watermarking algorithms make it possible that the original image can be totally restored after the watermark was extracted, so it is widely used in the protection of medicalimages. A new reversible watermarking scheme based on Integer Discrete Cosine Transform (IntDCT) and Difference Expansion (DE) is proposed in this paper. The IntDCT transformation not only avoids the distortion of truncation...
