OpenCV problem #24

Closed region23 closed 7 years ago

region23 commented 8 years ago

env: OS X 10.11.2 Go 1.5.2 OpenCV 2.4.12 Error when exec analyzer.FindBestCrop:

stat /usr/share/opencv/haarcascades/haarcascade_frontalface_alt.xml: no such file or directory
exit status 1

path created by homebrew is /usr/local/Cellar/opencv/2.4.12/share/OpenCV, not /usr/share/opencv/

if I rewrite path in crop.go, then I caught this error:

OpenCV Error: Unspecified error (The node does not represent a user object (unknown type?)) in cvRead, file /tmp/opencv20151230-64900-cukeo2/opencv-2.4.12/modules/core/src/persistence.cpp, line 5008

you can use NewAnalyzerWithCropSettings and configure the haarcascade file manually. I also use that openCV version from brew and this haarcascade file:

hope it helps :-)
