There are three components in this histogram equalization example. Video Partition partitions a big image into four non-overlapping small images for parallel histogram computation. HDLHistogram computes the acc
Plot Transformation Curve for Histogram Equalization Open Live Script This example shows how to plot the transformation curve for histogram equalization.histeqcan return a 1-by-256 vector that shows, for each possible input value, the resulting output value. (The values in this vector are in the...
Figures 14 and 15 show histogram equalization applied to our ongoing example images “students” and “books,” respectively. Both images are much more striking and viewable than the original. As can be seen, the resulting histograms are not really flat; it is “flatter” in the sense that ...

This example shows how to implement a contrast-limited adaptive histogram equalization (CLAHE) algorithm using Simulink® blocks.
This histogram equalization example meets the following requirements: Throughput must be sufficient to maintain a 1920x1080p video stream at 60 frames-per-second. Latency must be sufficiently low so as not to drop frames. To meet the video throughput requirement, the frame buffer throughput must ...

Histogram Equalization To transfer the gray levels so that the histogram of the resulting image is equalized to be a constant:The purposes:•To equally use all available gray levels;•For further histogram specification.This figure shows that for any given mapping function y = f(x) between ...
Table 4 presents the evaluation of 30 test images, demonstrating that the BHE3PL consistently yields EME values closely aligned with the input image for 28 of these, outperforming other traditional histogram equalization methods. For example, as shown in Image 1 , the EME value of BHE3PL is 2.1...
An example of histogram equalization is given in Figure 15.1. This process is very effective for images whose grey level distribution is narrow and shifted toward the origin leading to an image that is relative dark. The effect of histogram equalization is to redistribute the grey-levels over a...
