Object extraction using color separation in OpenCV

Question

Hi all I am developing an application where in i'm extracting red colored apple from the image. I have thresholded the image [cvInRangeS(imgHSV, cvScalar(160,100,40), cvScalar(180,256,256), imgThresh);] so that i'm able to get a binary mask of the apple. How can i combine that mask along with the original image, so that i will extract only the apple part from the original image...?

Answer 1

if your image is in HSV color Model try to convert it to RGB and than split it in 3 matrix R, G and B and run the threshold only on R channel you kann use the threshold (use the threshold Binray) result as mask with the copyTo. I hope this help!

Answer 2

You can use Mat::copyTo():

inputMat.copyTo(outputMat, maskMat);
