Many popular modern image processing software packages implement a naïve form of histogram equalization. This implementation is known to produce histograms that are not truly uniform. While exact histogram equalization techniques exist, these may produce undesirable artifacts in some scenarios. In this ...
Recognizing objects from large image databases, histogram based methods have proved simplicity and usefulness in last decade. Initially, this idea was based on color histograms that were launched by swain [1]. This algorithm presents the first part of our proposed technique named as “Histogram proc...

independently for each channel, as long as the number of channels is equal in the input image and the reference.2 Histogram matching can be used as a lightweight normalisation for image processing, such as feature matching, especially in circumstances where the ...
The implementation of histograms and histogram based processing are discussed in this chapter. Techniques of accumulating a histogram, and then extracting data from the histogram are described in detail. Histogram equalisation, threshold selection, and the use of clustering for colour segmentation and cla...
