Re: Image searching within another image
It definitely is possible but QNX does not provide any libraries for that.
Depending on countless factors you may either read in both images using existing API-s and do the search yourself along
the lines of a 2D strstr or rely on an image recognition library.
If you go with the roll your own solution approach but you hit performance issues then you can subsample both images
multiple times (using a factor of 2 can be implemented most efficiently) resulting in an image pyramid and do the search
at higher resolutions only in areas that gave a hit in lower resolutions.
