How can i write a code to detect the numbers and alphabets in an image?

[Walter Roberson]

That is likely to be difficult. Do you have control over the lighting and angle and distance? You would prefer a brighter diffuse light and to take the picture from directly above, I think...though taking it from a sharp angle with a strong light to get a profile image could be potentially useful to read those embossed letters.

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.

[Walter Roberson]

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
