For data set creation, we collected sheep images from local farms in Baita Village, Hohhot, Inner Mongolia, to create a sheep image segmentation dataset. To lighten the model, we replaced parts of the feature extraction network with Inverted Residual modules and incorporated Squeeze-and-Excitation (SE) attention mechanisms to maintain segmentation accuracy while reducing the model’s size. Additionally, we optimized the model’s feature fusion part using the Atrous Spatial Pyramid Pooling (ASPP) structure. Finally, we used the masks generated by the improved Mask R-CNN for counting. The results show that the improved Mask R-CNN-Inverted Residual-SE-ASPP sheep counting model achieved an accuracy rate of 96.27%, reduced the number of parameters by 38.46%, decreased computational complexity by 26.14%, reduced the model size by 34.52%, and increased single-frame inference speed by 22.12%.
