I have an application that compares sets of images and identifies if there are any duplicates. The user is then shown a list of thumbnails of the duplicates and has the option to delete them.
This all works great, but I'm concerned about the performance of the thumbnail generation. The quality of the thumbnail does not matter - the priority is to get the thumbnails generated as quickly as possible.
I can't seem to find anything through google that suggests a 'quick and dirty' thumbnail generation algorithm that has performance as its priority.
Any pointers or advice of how to achieve fast thumbnail generation (even if it means using a third-party library) would be much appreciated!
