KDE - Kernel Local Descriptors

This is a Matlab package that implements the kernel local descriptors presented in "Kernel Local Descriptors with Implicit Rotation Matching" at ICMR 2015 https://hal.inria.fr/hal-01145656.

What is it?

This code implements:

  1. Extraction of our local descriptor
  2. Descriptor post-processing (power-law and PCA dimensionality reduction)
  3. Evaluation on the Brown patch dataset

Execution

Run the following script:

>> extract
>> evaluate

Performance

False Positive Rate at 95% recall on Brown patch dataset:
