Export Eligible Fish Length Sorting System Based on Digital Image Object Interpolation

Sorting catfish manually requires a lot of time, yet it presents low accuracy. Export catfish farmers need better instruments to increase the yield of sorted catfish. Using the right method of image processing is one of the ways. Length is one of the parameters of export quality catfish. Somehow measuring the length is challenging as catfish has very smooth and flexible body. By using interpolation method and aerial image capturing technique, the average error is pretty small, only 5.97%.
