C++ Image Processing for Powerbuilder

I am seeking a skilled C++ developer who can write efficient code for image capture and background removal. This code is a part of a larger project and would be integrated into a Powerbuilder application. Below are key project details:

- Perform both image capture and background removal.
- The images to be processed are digital photographs, so your solution should cater to them specifically.
- The output of the processed images should be in PNG format.

Strong knowledge of C++, digital image processing, and Powerbuilder is ideal. A deep understanding of how to implement image capture and background removal in C++ is required. If you have experience in similar projects, it would be a great advantage.
The code will be updated or used as a DLL inside Powerbuilder.
