Texture Descriptors in MPEG-7
We present three descriptors of texture feature of a region. Namely, the homogeneous texture descriptor (HTD), the edge histogram descriptor (EHD), and the perceptual browsing descriptor (PBD). They are curren...

Spatial Frequency Band Division in Human Visual System Based-Watermarking
A good watermark is known to be perceptually invisible, undetectable without key and robust to spatial/temporal data modification. In this paper, we utilize the characteristics of the human visual system (HVS)...

Robust Contrast Enhancement for Microcalcification in Mammography
Microcalcification is important for early breast cancer detection. But due to the low contrast of microcalcifications and same properties as noise, it is difficult to detect microcalcification. In this paper, ...
