| Summary: | Microbial contaminants are usually the biggest problem faced by egg manufacturer. Bacteria usually penetrate the eggshell through cracks, micro cracks and translucent area are.
A fine-tuned Alexnet and a machine vision system were used for inspection of pattern of translucent area. Images 150 cracked egg and 30 intact eggs were taken. To fit into the Alexnet,
1010 images were cropped randomly within the boundary of egg in the size of 227×227×3 in size training and validation data at the ratio of 7:3. The trained network was then evaluated
qualitatively using Google Dream Images and quantitatively by visualizing and prioritizing channel with highest activation energy in each convolution layer. Extra 100 cropped images
were used as testing images. The trained network was able to detect reject defective egg with accuracy of 91% with false reject rate of 12.5%. The developed system acted as a preliminary study for the development of automated quality determination based on translucent area. |
