In this paper, we present a new scheme of data representation for image-based objects. It allows the illumination to be changed interactively without knowing any geometrical infor...
This paper proposes an RST-invariant multi-bit watermarking system based on LPM and DFT. This system embeds the watermark in a rotation and translation invariant domain obtained b...
A region-based video segmentation algorithm, which is based on 8 x 8 block, is proposed to segment moving objects in a video sequence. The proposed video segmentation can be perfo...
A texture image is of noisy nature in its spatial representation. As a result, the data hidden in texture images, in particular in raw texture images, are hard to detect with curr...
Face recognition has become an important topic within the field of pattern recognition and computer vision. In this field a number of different approaches to feature extraction, m...
