This paper presents a new hybrid color image segmentation approach, which attempts two different transforms for texture representation and extraction. The 2-D discrete wavelet transform that can express the variance in frequency and direction of textures, and the contourlet transform that represents boundaries even more accurately are applied in our algorithm. The whole segmentation algorithm contains...
Color histogram is a widely used feature in the area of content-based image retrieval. One of the shortcomings of color histogram is that it is sensitive to the location of histogram bin boundaries. Therefore, a novel color histogram calculation technique based on color point coverage is proposed. On the other hand, color quantization approach of HSV color space is studied in this paper. HSV color...
