Signal processing - object detection methods with usage of optical correlator

Abstract

This article describes the vertical traffic signs recognition (VTSR) system. In this system the Cambridge optical correlator is used as an image comparator in the recognition stage. In our case, the Cambridge optical correlator compares detected traffic signs with reference traffic signs. One step of the VTSR system is the traffic signs detection process. Traffic signs detection is used to locate the area of the traffic sign from the complicated captured image background. The process of location of the traffic sign might be based on different methods.
