getcv

Gets the grayscale/RGB/RGBA matrix R, which represents the pixels of the image handle.

Syntax

R = getcv(handle)

Inputs

handle: Handle of an image.; Type: integer

Outputs

R: R represents the pixels in h. For a grayscale or binary image, R will be a 2D real matrix. For color images, it will be a real, ND matrix, where the first slice represents the red channel, second slice represents the blue channel, third slice represents the green channel and the fourth slice represents the alpha channel, if applicable.; Type: matrix

Example

Get the pixel data of an image read with the ComputerVision library:


handle = imreadcv('cv1.jpg');
R = getcv(handle);
size(R)

ans = [Matrix] 1 x 3
