—Salient areas in natural scenes are generally regarded as areas which the human eye will typically focus on, and finding these areas is the key step in object detection. In com...
JPEG2000, the new standard for still image coding, Quantization, user defined wavelets, arbitrary wavelet provides a new framework and an integrated toolbox to better decomposition...
The geometric features of images, such as edges, are difficult to represent. When a redundant transform is used for their extraction, the compression challenge is even more dif...
