Spectral clustering and path-based clustering are two recently developed clustering approaches that have delivered impressive results in a number of challenging clustering tasks. ...
In this paper, we propose a color image enhancement method that uses retinex with a robust envelope to improve the visual appearance of an image. The word "retinex" is h...
We present a blind data hiding method for JPEG compressedimageswhichminimizesthe perceptualdistortion due to data embedding.The proposed systempresentsa number of op. tions to the ...
Information theoretic tools lead to the design and analysis of new blind data hiding methods. A novel quantizationbased blind method, which uses trellis coded quantization, is pro...
In this paper we propose a novel data hiding procedure called Quantized Projection (QP), that combines elements from quantization (i.e. Quantization Index Modulation, QIM) and spr...
