Histogram

Rgb histogram sideview in matlab

The following Matlab project contains the source code and Matlab examples used for rgb histogram sideview. Superposition of column profiles of an image. Example: -------- I = imread('danaide.jpg'); I2 = improfileadd(I); I3 = improfileadd(imrotate(I,-90)); I3 = imrotate(I3,-90); figure subplot(2,2,1), imshow(I) title('Input image') subplot(2,2,2), imshow(I2) title('Superposition of column profiles') subplot(2,2,3), imshow(I3) title('Superposition of row profiles')

Creates a lognormal distribution with desired mode (peak-value) . in matlab

The following Matlab project contains the source code and Matlab examples used for creates a lognormal distribution with desired mode (peak-value) . .  lognormal: creates lognormal distribution with desired mode (peak-value)  usage: lognormal(mode_log,sigma_n,n,plotit)  --- INPUT arguments: 'mode_log' ---> can be any positive value (is the most frequent value of the lognormal distribution -> the peak in the histogram) 'sigma_n' ---> standard deviation of the corresponding normal distribution

Log binning of data in matlab

The following Matlab project contains the source code and Matlab examples used for log binning of data.   This script takes in data, and then produces a logarithmically binned (natural log) histogram:   [midpoints,Freq,eFreq] =logbin(data, BinNum)   where the inputs are   data: the input data from some experiment which will be binned   BinNum: the number of bins used in the data reduction process.
