A Qt tool for Image Hashing with some perceptual hashing algorithms.

Qt-Image-Hash-with-multiple-methods

A Qt-based image hash system that implements 5 methods for efficient detection of similar images from an image database, given a host image.

You have to include opencv_world340.dll to start the project, which also requires support of opencv-contrib.

---

How to use:

Select Folder(database that contains images) and host image -> Select Hash Method(at the bottom of GUI, or use the default pHash) -> Generate Hash Code for all images in the folder(press F5) -> Get the most similar images by comparison of Hash Code(press F6).
