Details

Building credit card OCR can be accomplished in the following steps:

• Detect and use the edges in the image to find the contour representing the card. Then apply a perspective transform to obtain the top-down view of the card.

• Localize the four groupings of four digits on a credit card by applying a series of operations.

• Extract each of these four groupings followed by segmenting each of the sixteen numbers individually. Recognize each of the sixteen credit card digits by using template matching.
