Abstract

Abstract: Machine vision and image processing algorithm were applied to calculate the head rice milling rate with the rice outline. The pixels at the rice edge were detected by means of close imaging method.Since rice seems elliptic,the long axis of ellipse is used to realize fast calculation of head milled rice.In the present research,the correlation coefficient between the results found by machine vision detection and the d data obtained on manual detection is over 0.96.This detection procedure can be used in fast calculation of head rice milling rate.

Key words: machine vision, image processing, head rice milling rate
