A New Simple Vision Algorithm for Detecting the Enzymic Browning Defects in Golden Delicious Apples
This work addresses a domain-specific problem for agricultural quality control, but it is incremental as it applies existing methods to a new dataset.
The researchers tackled the problem of detecting enzymic browning defects on Golden Delicious apples using a vision algorithm, achieving a classification accuracy of 99.19% and an image processing accuracy of 97.15%.
In this work, a simple vision algorithm is designed and implemented to extract and identify the surface defects on the Golden Delicious apples caused by the enzymic browning process. 34 Golden Delicious apples were selected for the experiments, of which 17 had enzymic browning defects and the other 17 were sound. The image processing part of the proposed vision algorithm extracted the defective surface area of the apples with high accuracy of 97.15%. The area and mean of the segmented images were selected as the 2x1 feature vectors to feed into a designed artificial neural network. The analysis based on the above features indicated that the images with a mean less than 0.0065 did not belong to the defective apples; rather, they were extracted as part of the calyx and stem of the healthy apples. The classification accuracy of the neural network applied in this study was 99.19%
