histogramcv

Syntax

R = histogramcv(handle, bins, dims)

[R, R1] = histogramcv(handle, bins, 1)

Inputs

handle

Handle of an image.

Type: integer

bins

Number of bins in the histogram, the value must be a positive integer.

Type: integer

dims

Dimension of the histogram. Valid values are 1 or 2. A value of 1 will generate a 1D histogram and a value of 2 will generate A 2D histogram.

Type: integer

Outputs

R

Handle of the histogram image.

Type: integer

R1

Handle of the histogram image with axes information. This is valid only for 1-dimensional histograms.

Type: integer

Examples

Generate a 1D histogram for the input image:

handle = imreadcv('image1.jpg');
bins = 256;
dims = 1;
R = histogramcv(handle, bins, dims);
plothandle = imshowcv(R);

Generate 1D histograms with axes information:

handle = imreadcv('image1.jpg');
bins = 256;
[R, R1] = histogramcv(handle, bins, 1);
plothandle = imshowcv(R1);
