Hi,

do the introductory examples in the App Designer, it'll help you alot.

You have the image in a variable first, like you used imread() to read it in:

rgbImage = imread(fileName);
imshow(rgbImage);

Now you can process rgbImage just like it's a matrix, because that's exactly what it is. The fact that you display it in an axes does not matter at all. For example let's say you wanted to make it gray scale and threshold it to find regions brighter than 100 and then find their area and mean brightness. You'd do

grayImage = rgb2gray(rgbImage);
binaryImage = grayImage > 100;
props = regionprops(binaryImage, grayImage, 'Area', 'MeanIntensity')

See? It has nothing at all to do with displaying anything, though you can display the binary image or any other image if you want to.

If you have an actual error, you forgot to tell us what it is. Please paste back here ALL the red text of the error message.
