Mat
UMat(Unified Matrix)
memory copy
OpenCV 2.4
OpenCV OCL module
ocl namespace
OpenCV 3
OCL module
mat.copyTo(umat);
UMat umat = mat.getUMat( flag );
flag: ACCESS_READ/ACCESS_WRITE/ACCESS_RW/ACCESS_FAST
mat = umat.getMat( flag )
umat = cv2.UMat(mat)
mat = cv2.UMat.get(umat)
TAPI - Transparent API
Mat
-->UMat(Unified Matrix)
memory copy
导致耗时增加OpenCV 2.4
时 开发了OpenCV OCL module
: 使用ocl namespace
方式调用OpenCV 3
时OCL module
被放弃,使用 TAPI 替代Mat <-> UMat
C++
Python
