Abstract

The invention provides a scallop shell growing pattern segmentation and recognition method. After a scallop shell CT image is acquired, Gaussian kernel matching filter is used to enhance the tubular pattern matching. The enhanced image is iterated. Each time of iteration retains the pattern characteristic information, and acquired fine patterns are segmented. According to the invention, the comb shell CT image is used as an input image; Gaussian kernel matching filter is used to enhance the tubular pattern matching in the image; the image segmentation of full variational model image binarization is carried out; intersections in an image pattern network are recognized; the information of a large number of scallop growing points is acquired; and the premise of the scallop growth rate is further accurately calculated. Compared with a traditional time measurement method, the method has the advantages that simple and rapid measurement and calculation are realized through computer analysis; and the method has the advantages of high accuracy and large flux; and the method provides a basis for acquiring accurate breeding phenotype information for shellfish breeding in the future.

Description

technical field

[0001] The invention belongs to the technical field of shellfish genetics and breeding, and in particular relates to a method for segmenting and identifying scallop shell growth lines. Background technique

[0002] Shells are calcifications secreted by the mantle of shellfish to protect the soft body. Due to the influence of their own and seasonal environmental changes, shellfish will form growth lines in the process of secreting calcification to form shells. The texture appears as different fine grooves on the surface, different densities on the internal structure, and changes in elements on the composition. Studying shell patterns can not only obtain objective and rapid growth information (growth traits) of scallops, but also accurately reveal the specific growth process of shellfish life history, and more importantly, provide basic data for shellfish breeding.
