Abstract:

After an overview on state-of-the-art in key-point detectors, we introduce SCK which is a universal key-point detector built upon the theory of sparse coding. SCK can handle any visual structures (blobs, corners, junctions, and more) and has been analytically proven to be invariant to changes in illumination, spatial and rotational transformations. Results show SCK outperforms all the hand-crafted detectors such as SIFT, Harris Corner, etc, and compare favorably with recent deep learning based detectors, setting the stage for extracting high quality visual features.
