摘要

A laser light image on the apple surface was captured and digitized by a machine vision system to a 256 pixels × 256 pixels × 256 gray levels digital image. It was then smoothed by using a linear low pass filter, converted to a binary image at a threshold gray level of 15, and calculated for the size. The image size increases with the ripening of the apple. Measurements on 120 Golden apples showed a nonlinear negative relation between the image size and the firmness with a correlation coefficient (r) of 0.84. During shelf display, the image size increases linearly with time. This system can be used to evaluate the apple ripeness.
