Python Question

python - OpenCV mat::convertTo in python

Is there any function in the OpenCV python wrapper that does the same thing as Mat's convertTo method in OpenCV 2?

I basically want to call this function in python

out.convertTo( out, CV_32F, 1.0/255, 0 );


where out is a grayscale image.

I have already made use of cv.ConvertScale by keeping my dst argument as type CV_32FC1, but I am trying to keep my python code as cv2 conformant as possible. Any clues?

Answer

You can simply use Numpy functions for this.

eg :

res = np.float32(out)

scaling, you will have to do separately:

res = res*scaling_factor
