Histogram Examples

Here we find out the histogram of any gray level image by not using the command imhist(), which is an inbuilt one rather by without using the inbuilt command. Reader may verify the plot by comparing with that generated from using the inbuilt command.

This programme is about finding many examples of Ramanujam's Diophantine Equation. For mathematical formulas used in making this programme, I have referred to the article MATHEMATICAL MINIATURE 9.pdf by John Butcher, butcher@math.auckland.ac.nz.To circumvent the problem of editing the Greek...

The provided functions demonstrate a histogram-based measure for class separability, given the samples from two classes (binary classification problem). The proposed error classification estimation method is described in (B) and it is based on estimating the pdf of each class using histograms....

The histogram of the image gives the frequency of occurrence of the gray level. it gives the no. of times a particular gray level occurs in the image. In the case of a colour image,the histogram is expected to give the number of a particular colour has occurred in the image.

This programs creates a histogram with a "logicle" (aka biexponential) x-axis. This is generally used to display flow cytometry data. It will not create false artifacts for values near zero. For more information see "A new "Logicle" display method avoids deceptive effects of logarithmic scaling...

function histmat = hist2(x, y, xedges, yedges) Extract 2D histogram data containing the number of events of [x , y] pairs that fall in each bin of the grid defined by xedges and yedges. The edges are vectors with monotonically non-decreasing values.The code is optimized no loop inside, it can be...

These two examples, which were originally posted in the MATLAB newsgroup comp.soft-sys.matlab, demonstrate how to use the nested function capability of MATLAB 7.0 (R14) and later versions to reduce the number of parameters that need to be passed into and between callbacks inside a GUI M-file....

Function HISTF ('flexible histogram') extends Matlab's HIST by letting one bound displayed percentiles, set x-axis limits and y-axis maximum, set x bin size, and draw a marker line at given x position. In contrast to HIST, relative rather than absolute frequencies are displayed. (Note: when range...
