Method and device for fish flesh detection

Abstract

The invention relates to a method and a device for fish flesh detection. The method comprises the following steps of 1, acquiring a hyperspectral image of a fish flesh sample, wherein the hyperspectral image comprises spectral data of multiple wavebands, 2, extracting the spectral data of N feature wavebands, wherein N is greater than 1, and 3, utilizing the extracted spectral data of the N feature wavebands as an input value of a learning vector quantization model, and identifying if the fish flesh sample belongs to marine fishes or freshwater fishes according to an output value of the learning vector quantization model. The method and the device can realize fast and accurate identification of marine fishes or freshwater fishes and can realize fast and accurate detection of mercury content of fish flesh.

Description

technical field [0001] The invention relates to food detection technology, in particular to a fish detection method and device. Background technique [0002] "Food is the most important thing for the people", and diet is the first element for the survival and development of human society. "Disease enters through the mouth" refers to unhygienic and unsafe diet, which is the source of all diseases. In recent years, with the rapid growth of the consumption of livestock and poultry meat and its products, people have also put forward higher requirements for the quality of meat products. [0003] Fish products are an important source of nutrients such as proteins, amino acids, and fats required by the human body, and are an important part of people's diets. Fish meat is soft and easy to be digested and absorbed by the human body. Fish is very rich in nutrients and is deeply loved by people. Therefore, research on the quality of fish meat has become a hot spot that people pay att...
