1. A computer-implemented encoding method of fruit texture atlas information, the computer-implemented encoding method comprising:
obtaining an image of fruit pedicel part and an image of fruit navel part, of a fruit to be encoded;
graying the image of fruit pedicel part and the image of fruit navel part, respectively, and normalizing the images to transform the images into a rectangular image of fruit pedicel part and a rectangular image of fruit navel part;
extracting features from the rectangular image of fruit pedicel part and the rectangular image of fruit navel part, respectively, encoding the features to obtain a fruit pedicel feature code table and a fruit navel feature code table; and
performing a merging operation on the fruit pedicel feature code table and the fruit navel feature code table to obtain a combined bidirectional feature code table, thereby forming a fruit texture atlas that uniquely identifies the fruit.
