Real Time Object Visual Inspection Based On Template Matching Using FPGA
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 8
Abstract
In similarity measure, normalized cross-correlation has found application in broad range of in image processing. This work proposes a novel technique aimed at improving the performance of exhaustive template matching based on NCC. An effective sufficient condition, capable of rapidly pruning those cross correlation score with respect to the current best candidate, can be obtained exploiting an upper bound of the NCC function. In this work Real-Time FPGA accelerates time consuming NCC template matching was presented. With this type of template matching we can inspect any industrially manufactured product on its production line with high accuracy, with increased speed of matching where huge amount of production is concerned. We got Good results by reducing search window size by reducing complexity in matching template.
