Method and means for detecting internal larval infestation in granular material

摘要

A method for detecting internal larval infestation in granular material comprising the steps of: creating an image of grain kernels in the near Infra-Red region; applying a mask to the image to exclude interference on the outer reaches of the kernel; forming a model kernel by applying a medium filter and slightly enlarging the resulting approximate model; comparing the masked image with a model kernel to obtain a difference image; and applying a threshold to difference image to determine larval infestation.
