Matrix Size of my images

Hi. how do i check the matrix size of my image?

Answer 1

[Image Analyst]

[rows columns numberOfColorChannels] = size(yourImageArray);  % Best way

For images, make sure you use the third output argument. Otherwise if it's a color image and you do

[rows columns] = size(yourImageArray);  % unsafe way to do it.

then your columns will actually be columns multiplied by the number of color channels (3) in your image.

@Esther: It is not surprising that the command size determines the size of arrays. I recommend to read the "Getting Started" chapters of the documentation to learn at first the basics and at second how to find related information in the docs.
