Detecting periodic patterns with the Modulo matcher
Adrienne Othon · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1995
The Modulo matcher was developed to detect the periodic presence of features in imagery. It was used for detecting and counting trains within a rail corridor. The Modulo matcher is a variant of the Hough transform and uses modulo, phase and along-corridor position to parameterize the transform space. The Modulo matcher was optimized to prevent search through empty transform space while also reducing memory requirements. Construction of the transform space is incremental and data driven.
