Embodiment

[0118] 1. Take the image of the cross section of the bull's eye muscle

[0119] First, the beef marbling grading device of the present invention is used to capture the image of the cross-section of the bull's eye muscle, and the image data of the cross-section of the bull's eye muscle enters the main control computer 8 through the image acquisition card 7 and is provided to the computer intelligent image analysis software system for intelligent analysis.

[0120] 2. Segmentation of the ocular muscle region on the cross section of the bull's eye muscle

[0121] 1. Select new parameters in the HSV color space for the taken cross-section image of the bull's eye muscle, and use the threshold method to roughly segment the eye muscle area, which is conducive to generating images with obvious gradients

[0122] see Figure 5 -a, in beef marbling images there will be "bridges" between the ocular muscles and epiphytes, appendages around the ocular muscles, and unevenly cut cross-secti...

Abstract

The invention discloses an image processing method for beef marbling grade scoring, aiming at solving the problem that the manual scoring method has large subjectivity and arbitrariness. The method comprises the following steps: intaking a cross section image of cattle eye muscle; segmenting the eye muscle region on the cross section of the cattle eye muscle; extracting the marbling in the eye region and scoring on the grade of the marbling in the eye muscle, wherein, the grade scoring of the marbling in the eye region comprises that an index system of the grade scoring of the beef marbling and the grade scoring of the marbling in the eye region are established and four parameters of area density Sd and number N, distribution coefficient CVr and size uniformity CVs of the marbling are selected as scoring indexes. The invention also provides a beef marbling grade scoring device comprising a light source, an image acquisition card, a main control computer, a data acquisition card, a camera and a photoelectric sensor; and the beef marbling grade scoring method and the device are used for productive enterprises and inspection departments.

Description

technical field [0001] The invention relates to an image processing method for beef marbling grade scoring based on computer vision technology in the field of automatic beef quality grade detection by beef production enterprises and product inspection departments. Background technique [0002] Beef marbling score is an important basis for beef grade evaluation. At present, most of the production uses manual evaluation by evaluators. When scoring, the evaluators rated the beef marbling grades according to the standard sample map of beef marbling and the evaluators' own experience. The manual scoring method has great subjectivity and randomness, which challenges the accuracy and authority of the scoring results. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to overcome the defects of large subjectivity and randomness of the manual scoring method, and provide an image processing method for beef marbling grade scoring in the...
