I was writing code for bi-linear histogram equalization. In that how to find slope equations above and below the local mean value?
I could find till mean. Even I want to know about weighting factor and mapping value concept. ....etc

Here, the fast image contrast enhancement is achieved based on histogram equalization (HE) both for color images and the gray-level images. A process called Multi-HE is proposed for the gray-level images. In this method, the input image is decomposed into several sub-images and then the classical HE process is applied to each of the sub-images separately. Also two different discrepancy functions are proposed for the purpose of decomposing the input image. Many simulations have been run and they show that both these methods are better in preserv ....etc

Histogram and histogram processing


Histogram: application
Distribution of gray-levels can be judged by measuring a histogram
Histogram provides global descriptions of the image (no local
details)
Fewer, larger bins can be used to trade off amplitude resolution
against sample size. ....etc

Abstract

Histogram equalization is a method in image processing of contrast adjustment using the image's histogram.This method usually increases the global contrast of many images, especially when the usable data of the image is represented by close contrast values. Through this adjustment, the intensities can be better distributed on the histogram. This allows for areas of lower local contrast to gain a higher contrast. Histogram equalization accomplishes this by effectively spreading out the most frequent intensity values.The method is usefu ....etc

can anyone help me to write code for histogram equalization using vhdl?? ....etc

In order to implement the adaptive equalizer, we need to generate a reference signal for the adaptive
algorithm. For the initial adaptation of the filter coefficients we need at the receiver to be able to
generate a replica of the transmitted data sequence. This known sequence is referred to as the
training sequence.
How can I do this? ....etc
