From Your Perspective - A Nerdy Journey
summary
Client needs phone OCR to read insurance cards at weird angles; development takes about a month of math and ends with a working demo that warps photographed corners into a front-facing image. Solution computes the homography using linear algebra, applies it as a 4x4 matrix and renders with the matrix3d CSS transform, then feeds the result into OCR. A phone rectangle detection API helps capture corners, and the feature ships and succeeds with the client.
