- Here is a simple script to show how we can do image search using open-cv, by ImageHash and SIFT algorightm.
- This can be used to face-detection, pornographic images detection, as well as many other applications where image similarity is needed.
Q&A: If you have problem with AttributeError: 'module' object has no attribute 'xfeatures2d'. Basically you need install opencv-contrib-python since starting from open-cv 3.0 SIFT is no longer free for business use. But you can still twig a bit on top of that, it is no thing but a bunch of mathmatic programming.
