I have an image with a white border around it, and I need to get rid of the border. There are 20 rows of white pixels above the image, 5 columns of white to the left, 5 of white columns to the right, and 5 rows of white below the image. I wan't to crop the image exactly out of that border, how do I do this in matlab? Thanks for any help you can give!
(The image is a tiff, which is why I can't use an online service for this, they won't let me upload .tiff)
What you need is the built-in MATLAB function imcrop. To use it, specify something like
B = imcrop(A,[xmin ymin width height]);
if A is your original image. First find the dimensions of your image. Say its 800 by 600. Then you are looking to crop a 770 by 580 image so these numbers respectively will be your width and height in the above function. Your x and y would be something like 5 and 20, respectively.
