Extract multiple images from a single image

I have a big image (3064x7535x3). I need to crop multiple images ( as many as possible) with the size of 218x178x3 from that single image and save those image in .jpg on a forder.

I could not figure it out how to do it. Any suggestion?

Thanks

I estimate there are more than 20 million images that size that could be extracted.

Are there restrictions as to how much overlap is permitted between the output images?

There is no restrictions ...

[Walter Roberson]

So to confirm, you want to output

BigImage(1:218, 1:178, 1:3)

and

BigImage(2:219, 1:178, 1:3)

and

BigImage(1:218, 2:179, 1:3)

and so on? If so, if every consecutive subset of the appropriate size is to be output, then you will have 2847 x 7358 = 20948226 different output images to write to files.

C = mat2cell(YourBigImage(1:3052, 7476,:), 218*ones(1,4), 178*ones(1,42), 3);

Now C will be a 4 * 42 cell array, each entry of which is a non-overlapping sub-image from the original array. You can then save each of those 168 images to an individual file. You will have to decide on the naming convention for the file, though.

I follow your code suggestion. But got this error.

I attached the screenshort of error message.
