We show that dispersive propagation of light has properties that can be exploited for extracting features from the waveforms. This discovery is spearheading development of a new class of digital algorithms for feature extraction from digital images with unique and superior properties compared to conventional algorithms. In certain cases, these algorithms have the potential to be an energy efficient and scalable substitute to synthetically fashioned computational techniques in practice today.
