Hi Walter, I have control over the light and camera view. I can capture brighter images.However, my major challenge is the principle to base my algorithm on. Since the light intensity doesn't really vary about the embossed letters.

You currently have bright on one side of the box and comparative dim on the other side of the box. That makes it difficult to even find a correct bounding box to be able to isolate the box to have a chance to do threshold detection to find the letters. The specular reflections of the gold also make it difficult. I think better illumination would reduce the problems.

You need better image capture conditions, such as alignment and lighting. Then do a background correction. Then look at the Computer Vision System Toolbox, which has OCR capabilities. https://www.mathworks.com/help/vision/ref/ocr.html#bt548t1-2_1
