Adaptive Threshold in OpenCV (Version 1 - the swig version)
- by Neil Benn
Hello
I'm trying to get adaptive thresholding working in the python binding to opencv
(the swig one - cannot get opencv 2.0 working as I am using a beagleboard as the cross compiling is not working yet). I have a greyscale image (ccg.jpg) and the following code
import opencv
from opencv import highgui
img = highgui.cvLoadImage("ccg.png")
img_bw = opencv.cvCreateImage(opencv.cvGetSize(img), opencv.IPL_DEPTH_8U, 1)
opencv.cvAdaptiveThreshold(img, img_bw, 125, opencv.CV_ADAPTIVE_THRESH_MEAN_C, opencv.CV_THRESH_BINARY, 7, 10)
When I run this I get the error:
RuntimeError: openCV Error:
Status=Formats of input arguments do not match
function name=cvAdaptiveThreshold
error messgae=
file_name=cvadapthresh.cpp
line=122
I've also tried having both the source and dest arguments both the same (greyscale) and I get the error 'Unsupported format or combination of formats'.
Does anyone have any clues as to where I could be going wrong?
Cheers,
Neil
