As one of the most significant local features, corners play a fundamental role in 3D computer vision and computer graphics. Two novel corner detection algorithms for 3D mesh data are presented in this Letter, in which the authors examine the geometric properties of the surface in multi-scale space and utilise simple triangle principle to detect mesh corners. Numerical experiments show that our corner...
The least-significant-bit (LSB) technique is one of the commonly used steganographic algorithms in the spatial domain. In most existing schemes, they didn’t carefully analyze the relationship between the image content itself. Hence, the smooth areas in the cover image will inevitably be contaminated after hiding even at a low embedding rate, thereby leading to poor visual quality and low security...
In this paper, we present a new method to perform overlapped block motion compensation (OBMC) using the modified Sigmoid window (MSW). The proposed MSW-OBMC method uses a variable weighting function to generate a window in order to maximally reduce the blocky artifacts on the edges of the block under consideration. It can be applied in any block partitioned motion compensation scheme. Benchmarked...
