Kernel based−methods using color histogram approach are recently used for visual tracking due to their efficiency and robustness. However, a color histogram suffers from the inability to encode spatial image information, thus images with very different appearances can have similar color histograms. This problem is especially critical in various applications such as retrieval for image and video...

Integral histogram image can gather speed the computing process of feature algorithm in computer vision, butex habits high working out complexity and incompetent memory access. In this paper, we propose a configurable parallel architecture to improve the computing efficiency of integral histogram. The design in the several integral objects is well supported for an integral histogram image such ...

A conventional color histogram (CCH) considers neither the color similarity across different bins nor the color dissimilarity in the same bin. Therefore, it is sensitive to noisy interference such as illumination changes and quantization errors. Furthermore, CCHs large dimension or histogram bins requires large computation on histogram comparison. To address these concerns, this paper presents ...

Histograms are the basis for numerous spatial domain image processing techniques. Histogram manipulation can be used effectively for image enhancement. In addition to providing image statistics, the information inherent in the histogram is also quiet useful in other image processing applications, such as image compression and segmentation. Histograms are simple in manipulation as well as econom...

In this paper a new desired histogram method is proposed to enhance the contrast of bimodal SAR images using histogram specification with Gamma distribution. The method is aimed to estimate the statistical parameters of the original histogram as the means and prior probabilities of the two modes using the Maximum Likelihood Gamma Distribution technique (ML). Next, we separate the two modes by s...

This study aims to increase the retrieval efficiency of proposed image retrieval system on the basis of color content. A new idea of feature extraction based on color perception histogram is proposed. First, the color histogram is constructed for HSV image. Secondly, the true color and grey color components are identified based on hue and intensity. The weight for true and grey color components...

Developments in multimedia technology, increasing number of image retrieval functions and capabilities has led to the rapid growth of CBIR techniques. Colour histogram could be compared in terms of speed and efficiency. We have presented a modified approach based on a composite colour image histogram. A major research perspective in CBIR emphasize on matching similar objects based on shape, col...

Color histograms are the most commonly used features for image retrieval due to the good attributes of image translation and rotation invariance. However the traditional color histogram features are usually short of spatial structural information which may cause error retrieval results. This paper presents a color image retrieval method based on Weighted DCT Spatial Combination Histogram (WDSCH...
