Root Cause

CUDA operation not available for GpuMat type or channels.

generic

Workarounds

  1. 88% success Check supported types in CUDA module docs before upload to GPU
  2. 85% success Convert to compatible type: gpu_mat.convertTo(cv2.CV_32F)

Dead Ends

Common approaches that don't work:

  1. Convert to CPU Mat for every operation 70% fail

    Defeats GPU acceleration purpose

  2. Change Mat type blindly 80% fail

    Data corruption or wrong results
