I have two images in opencv: Image A and Image B.
Image A is output frame from camera.
Image B is alpha transparent image obtained by masking one image.
Before masking Image B it is warped with cvWarpPerspective()
cvAddWeighted()
- It looses intensity when you give alpha and beta valuePlease help me out with something where I don't lose intensity in the output image after blending.
Thanks in advance
I finally got the answer.It consist of 5 steps....
Step - 1
cvGetPerspectiveTransform(q,pnt,warp_matrix);
//where pnt is four point x and y cordinates and warp_matrix is a 3 x 3 matrix
Step - 2
cvWarpPerspective(dst2, neg_img, warp_matrix,CV_INTER_LINEAR)
//dst2 is overlay image ,neg_img is a blank image
Step - 3
cvSmooth(neg_img,neg_img,CV_MEDIAN); //smoothing the image
Step - 4
cvThreshold(neg_img, cpy_img, 0, 255, CV_THRESH_BINARY_INV);
//cpy_img is a created image from image_n
Step - 5
cvAnd(cpy_img,image_n,cpy_img);// image_n is a input image
cvOr(neg_img,cpy_img,image_n);
Output - image_n (without loosing intensity of input image)
