The invention provides a computer vision-based tuna surface shape texture feature automatic extraction method and application. Datum points of three tuna images are pre-positioned through computer vision, and a texture feature region is determined and automatically intercepted by moving the datum points. Gray level conversion and gray level quantization processing are carried out on the texture image, gray level co-occurrence matrix calculation is carried out on the quantized gray level image, and normalization processing is carried out on the gray level co-occurrence matrix; six texture indexes are calculated through a normalized gray-level co-occurrence matrix, the variation trend of the distance and direction of the texture indexes is analyzed, the texture indexes of tuna are analyzed through factors, an earlier-stage foundation is laid for intelligent identification of tuna, and reference is provided for automatic extraction of phenotypic textures of other fishes.
Description
technical field [0001] The invention belongs to the technical field of fish basic biology automation, and relates to a computer vision automatic extraction method and application of tuna surface texture features. Background technique [0002] Texture is a ubiquitous visual phenomenon, which is a basic property of the surface or structure of an object, and different objects have their own texture characteristics. Texture analysis has also been applied in fish biological research, such as fish species classification and identification, fish tissue analysis, fish muscle identification, fish behavior detection, fish feeding assessment and so on. Among them, texture analysis is mainly used in fish species classification and identification, and the acquisition of fish phenotype texture information is the key to fish species classification and identification. Because fish phenotypic texture is naturally generated during the growth process, it is mainly distributed on the surface o...
