[PDF] Image Processing for Stress Cracks in Corn Kernels ...

ABSTRACT AN image processing algorithm was developed for detecting stress cracks in corn kernels using a commercial vision system. White light in back-lighting mode with black-coated background having a small aperture for the light provided the best viewing conditions. The kernel images, when processed using the algorithm developed, produced white streaks corresponding to the stress cracks.

Image processing was used to inspect stress cracks of corn kernels by Gunasekaran et al. (1987). The back lighting mode with a black-coated plate as a background was adopted to obtain images with high contrast between the stress cracks and the rest of the kernel. They developed image processing algorithms to extract the stress cracks as streaks ...

Size Characterization of Stress Cracks in Corn Kernels

1972); and large and rounded kernels stress crack more readily than flat kernels (Thompson and Foster, 1963). Equally important as moisture and thermal stresses are the mechanical impact stresses. Roberts (1972) observed that 26% of combine shelled corn had stress cracks before the corn was artificially dried. Corn shelled

May 01, 2020  According to the yielding criterion of von Mises stress, when the von Mises stress of corn kernel exceeded its yielding stress, corn kernel will develop cracks (Wang et al., 2018; Wu et al., 2017). Therefore, in order to predict the stress cracks of corn kernels during drying process, it was necessary to collect the maximum von Mises stress in ...
