Abstract: The rapid identification and precise positioning of the freshwater fish's head, abdomen, and fins are prerequisites for the robot to achieve fast capturing, accurate segmentation, and the core of working efficiency improvement. The freshwater fish body's semantic segmentation algorithm conducts many invalid feature channels under the encoding feature extraction stage, and the constant network sample collection and pooling operation lead to the loss of detailed information of some fish bodies, decreasing the performance and poor the performance effect of edge cutting. A semantic segmentation algorithm base on SENet optimized Deeplabv3+ freshwater fish head, abdomen, and fins is proposed. Using dilated/atrous convolutions to enlarge the receptive field, prevent detail information loss, and actualize the precise positioning. Meanwhile, the SENet optimization enables Deeplabv3+ to improve the useful feature of freshwater fish and restrains its ineffectual feature. Eventually, the semantic segmentation MIoU of each part of the freshwater fish reached about 93% on the self-established freshwater fish data set. Its feature improved significantly and reached the current advanced segmentation level.
