Hi, i am new to matlab and need some help with this
i have used imread to read in a jpg image. however the workspace reads this as a 3 dimensional matrix, e.g. 150x100x3 uint8
how can i change this to a 2 dimensional matrix? i believe i have to use a gray scale image to accomplish this, but i cant seem to get it to work.
a = imread('image.jpg')
b = gray(a);
secondly, how can i read in a bunch of images into matlab for processing? i.e. i want to read in 1.jpg, 2.jpg, 3.jpg into the workspace. I know I need a for loop ,but i can't quite put the code together using the imread syntax.
for i = 1:5
a(i) = imread(xxxxx.jpg);
