Face Detection

[jokull]

Has anyone implemented face or object detection on top of Wand? I would like the ability to create thumbnails where an area of interest is included. Thumbor has a nice description of how this works (Thumbor is based on PIL, but object detection is done by OpenCV).

Although I think facial detection is closer to computer vision than image processing, it would be great if Wand provides it. I will look into this later.

The only CV that ImageMagick supports is Hough-Line, & Canny edge detection algorithms. I don't think Face Detection is realistic for this module. Perhaps if there's a wand.contrib sub-module that would allow community members to offer solutions to real-world problems (like how Flask manages non-core features).
