Robust Image Hashing Using Higher Order Spectral Features
2010 International Conference on Digital Image Computing: Techniques and Applications
Robust image hashing seeks to transform a given input image into a shorter hashed version using a keydependent non-invertible transform. These image hashes can be used for watermarking, image integrity authentication or image indexing for fast retrieval. This paper introduces a new method of generating image hashes based on extracting Higher Order Spectral features from the Radon projection of an input image. The feature extraction process is non-invertible, nonlinear and different hashes candoi:10.1109/dicta.2010.26 dblp:conf/dicta/ChenC10 fatcat:ujfhilqoejam7hjsis3jpdx76a
