Method for rapidly identifying Atlantic salmons and rainbow trout based on machine vision

Abstract

The invention discloses a method for rapidly identifying Atlantic salmons and rainbow trout based on machine vision and belongs to the meat product quality detection technology field. The method comprises the following steps of preparing samples of the Atlantic salmons and the rainbow trout, and shooting and collecting sample images through using a mobile phone; inputting the obtained images intoa computer and carrying out image processing; carrying out characteristic data extraction on the processed images; using a principal component analysis method to carry out dimension reduction processing on the extracted characteristic data; using a chemometrics method to establish a rapid identification model of the Atlantic salmons and the rainbow trout; and carrying out image collection on unknown fish samples to be tested, and using the established identification model to identify a category of the unknown fish samples to be tested. By using a detection method in the invention, operation isconvenient, the samples are not destroyed, a detection speed is fast and a result is objective and accurate. By using the method, the Atlantic salmons and the rainbow trout are identified. When a principal component number is 6, identification rates of an established LDA model training set and a test set can reach 100% so that rapid identification is achieved.

Description

technical field [0001] The invention belongs to the technical field of meat product quality detection, and in particular relates to a machine vision-based rapid identification method for Atlantic salmon and rainbow trout. Background technique [0002] With the development of my country's economy and the improvement of people's living standards, salmon with rich nutrition and delicious taste is more and more favored by consumers, and the salmon industry is developing rapidly. In the Chinese market, salmon includes a wide variety of fish, including Atlantic salmon, Pacific salmon, salmon, rainbow trout, etc. Although these fish species are all called salmon, they have different edible values ​​and market prices. Because the price of rainbow trout in the market is usually lower than that of Atlantic salmon, and consumers have a strong demand for Atlantic salmon that can be eaten as sashimi, unscrupulous traders shoddy and confuse the logo in order to make profits, and sell che...
