python3-mrgingham 1.22-1build1 (riscv64 binary) in ubuntu noble

 Given an observed image containing a chessboard or a grid of circles, mrgingham
 locates the board in the image, and precisely computes the location of the
 chessboard corners (or circle centers). This is similar to the routines in
 OpenCV, but is faster and more robust.
