Meat quality detection system and method based on ultrasonic signals

Abstract

The invention belongs to the technical field of ultrasonic image processing, and particularly relates to a meat quality detection system and method based on ultrasonic signals. The meat quality detection system based on the ultrasonic signals comprises an ultrasonic image collection device, a texture extraction module and an image sampling module, wherein the ultrasonic image collection device is used for collecting an ultrasonic image of meat to be detected; the texture extraction module is used for extracting the texture characteristic of the ultrasonic image through the texture extraction algorithm to obtain a texture image; the image sampling module is used for calculating the pixel mean value and the pixel variance value of the texture image and judging the texture evenness of the texture image according to the pixel variance value of the texture image. By the adoption of the bi-dimensional empirical mode decomposition and the bi-dimensional spectral characteristic, the texture image is obtained, the texture evenness of the texture image is judged according to the pixel variance value of the texture image and serves as an index for evaluating the quality of the meat, the system is simple, operation is convenient, and the quality of the meat is reflected visually, rapidly and accurately.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic image processing, and in particular relates to a meat quality detection system and method based on ultrasonic signals. Background technique [0002] Meat and its meat products can provide the protein, fat, inorganic salts and vitamins needed by the human body, and are an important source of nutrients for human beings. With the continuous progress of the society and the rapid development of the economy, people's living standards continue to improve, consumer demand is increasing, more and more attention is paid to the health of the diet, and the requirements for meat quality are constantly improving. At present, the evaluation of meat quality is mostly traditional subjective sensory evaluation or conventional instrument measurement, etc. Subjective sensory evaluation mainly relies on subjective factors such as human vision and experience, lacks objectivity, and has low evaluation accuracy. Alth...
