Currently doing the OCR gui that have two buttons, one to load the image and another one is the process. Its quite simple. So, i have an error on the process part, the Mser function. The load image i code it like this :
global I
colorImage = rgb2gray(I);
I=im2double(I);
Then, i have problem on the next part. Being using this code Automatically Detect and Recognize Text in Natural Images.

Why don't you input the image as it is intended: as an input? You seem to be using a global to inject your input into the function, but you still call it with an input in your GUI (the Recognition_Callback function). It looks like you're expecting the variable I to be shared automatically, which is not how global variables work. Consider replacing the way you pass the image into that function with a method that doesn't work with globals. Generally guidata will work well.

I guess based on the name of the variable "im", that the software expects a gray image, which is a 2D matrix, but you provide an RGB image, which is a 3D array.

"But still error" is less useful than posting a copy of the complete error message. I do not have your input data and toolbox functions, so maybe I'm not able to run your code. But you do have the error message on your screen already, so please share this valuable information with us.
It is easier to solve a problem than to guess, what the problem is.
