Trying to generate a histogram from my real-time webcam input. The video is transformed to grayscale and I’m trying to create a histogram from it.
For this, I try to use the “calcHist” function from the ofxCv library. When I do it with a still image it works, however when I try the same code with my camera input it gives the error; “no matching function for call to calcHist()”
Does anyone know where I should look for this?
Thank you very much!
