Hi, It's better to do image/video pre-processing before extracting any usable information from images/videos. Reducing the amount of unnecessary information in a given image/video is a vital part when it comes to increasing final accuracy. (ex : grayscale transformation/ image restoration etc.)
Another important section to explore is which algorithm to use in order to detect shapes/features. For example, number detection program should detect edges, and image processing techniques used[1][2][3] should enhance edges in a given image to make it easy to extract these features. Often accuracy of these algorithms depend on image noise level, brightness level etc. Therefore, we might need evaluate the accuracy of different algorithms for different types of images as well.
