Don't have enough karma points to reopen the question, but I figured out the solution. I imported the overlay image as a 4-channel image, and converted the underlay image into a 4-channel image.

2017-01-23 04:43:59 -0600 | asked a question | Unexpected results while copying transparent image over another image. I have a transparent PNG image (shown below)... and another image (shown below) I want to copy the resize the first image and place it over the second image, and I tried doing so using the resize() and copyTo() functions. But the result was not what I expected or wanted... How do I get rid of that green color in the background? EDIT - So, I did further research and found that this is probably because I am using a three channel image and I need to use a four channel image. So how do I convert a 3-channel image to a 4-channel image? |

I actually rage quit by deleting directory where I installed the files. So, right now, I'm rebuilding them. But I think I remember seeing a "opencv_world320.dll.a". So, in any of my further projects, Do I just link to that library, and that's it? |
