Embodiment Construction
[0030] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited.
[0031] (1) Prepare samples of Atlantic salmon and rainbow trout, and use mobile phones to capture images of samples:
[0032] The Atlantic salmon samples come from 3 batches. The middle part of the fish is selected, and the fish pieces are divided into length×width×height about 3×3×1cm in the aseptic refrigerator and numbered. There are 20 pieces in each batch, 60 pieces in total. Rainbow trout samples were selected in the same manner as Atlantic salmon. Place the sample on a clean white board, adjust the light source, and use a mobile phone to collect an overhead image of the fish sample.
[0033] (2) import the image obtained in the step (1) into the computer, and carry out image processing:
[0034] Take one of the Atlantic salmon images as an example, and the rainbow trout image is processed i...
