This is Python implementation of Weber Local Descriptor described in this paper. Current implementation is simplified version of one described in paper, it only uses Differential Excitation component. It's implemented using convolution operator from Scipy package for better performance.
This implementation requires Python version 3.5 or later to run. It also needs Scipy and OpenCV packages. All dependencies are described in requirements.txt
Example of usage:
