Proportion of pixels in black

my question is that how to find the proportion of black points after converting the image into black and white. I have alreay converted the image using im2bw(the_resized_image) and resized it to make it smaller. I know you can find the sum or use logical expressions, just don't know how to implement it. any help would be greatly appriciated.

Just try

sum(I(:))        % number of white pixels

if thats for the white pixels, what would i do to get the black?

[darova]

You have only 0 and 1. You converted your image to binary

Can you find the number of all pixels?

[Oscar Tsang]

divide by the size of the image right??

[darova]

Exactly! You are reading my mind!
