Using Python 2.7 and OpenCV 3.1. Grayscale + Blur + External Edge Detection + Segmentation of each area in the Receipts (for example "Category" to see later which one is marked -in this case cash-). I find complicated when the image is "skewed" to be able to properly transform and then "automatically" segment each segment of the receipts. Example:
