Well, did you try my code below? If not, why not? If it's not what you want, then explain better exactly what "identify" means to you.

It's a constant and uniform gray level, so just detect that. For example if it's gray level is 175, do
scaleMask = grayImage == 175;
scaleMask = bwareafilt(scaleMask, 1); % Take largest blob.
scaleMask = imfill(scaleMask, 'holes'); % Fill holes to get rectangular block.
Not sure what you want to do after that.

Glad it's working for you. Do you want to post the final code so that people won't post here for years to come "Can you please upload your code?" as they always do.
