IMAGE DIGITIZATION BY WAVELET COEFFICIENT WITH HISTOGRAM SHAPING AND SPECIFICATIONMany applications of histograms for the purposes of image processing are well known. However, applying this process to the transform domain by way of a transform coefficient histogram has not yet been fully explored. This...

In situations where a particular histogram shape, capable of highlighting certain gray level ranges, is desired, another method known as histogram specification can be used. This transforms an image so that its histogram more closely resembles a given histogram. An image, f(x, y, z), with a...
[33] divided and rebuilt the histogram of the DCP result in terms of the foreground and background distributions, then applied histogram specification to fit the rebuilt histogram [33]. Chen et al. [34] combined the HE and gamma correction as Bi-Histogram modification to flexibly adjust the ...
The intensity of pixels in the dequantized image tends to be unique, so a strict ordering for histogram specification may be applied. Similarly, the proposed method performs dequantization as an intermediary step, and can therefore be incorporated into a similar pixel ordering framework. While ...
