I was wonder that once i create a mask from the image, is there any way that i can ask the matlab to generate the matrix of image based on the logical value from the mask. In orther words, if i have a mask that labels the ball, how can i apply the mask to the image to only shows the pixels of ball.
I am mainly looking for array operation since for loop that iterate through height and length is quit slow.
Lets take a look on a example in 2D matrix.
Matrix = [ 3 4;
Logical= [ 1 1 ;
I want to have a result:
R = [3 4;
Thank you in advance!
