Root Cause

Mat data type doesnt match expected operation input.

generic

Workarounds

  1. 90% success Convert explicitly: img.astype(np.float32) or img.convertTo(CV_32F)
  2. 88% success Check required type in function docs before calling

Dead Ends

Common approaches that don't work:

  1. Convert all images to CV_8UC3 72% fail

    Loses depth information for float/16bit images

  2. Ignore type and cast pointer 90% fail

    Undefined behavior, segfault risk
