Input image size in MATLAB

Question

Hi I am trying to get the image size of the uploaded image in MATLAB. So far I have got :

read=imread(image.png)

ymax=size(read) (1);
xmax=size(read) (2);

However this gives me an error. The image size is 300px by 256px, and I want my ymax and xmax to automatically get the pixel values. How do I do this?

Answer 1

It's not a MATLAB'ish way of doing that, try:

[xmax, ymax, nchan] = size(read);

Where nchan is the number of channels. Also it can be done by:

xmax = size(read, 1);
ymax = size(read, 2);

Or even:

[xmax, ymax, ~] = size(read);
