The primary task in preprocessing image is moving estimation and compensation of image senor, that is to say, correction problem of image background. In this paper, a new method of motion background compensation based on robust regression is proposed. The background motion velocity is calculated by the estimation of the optical flow field model. Then robust iterative weighted least square method is...
Characteristics of rice appearance quality are very important to evaluate rice quality and pricing. The normal method for determining rice quality is based on manual inspection which is an inefficient way and resulting in unconstant outcomes. Thus, we developed an automatic system relying on the machine vision which allowed us evaluate rice appearance quality including rice chalkiness and shape. In...
