ABSTRACT=Pig behavior recognition serves as a crucial indicator for monitoring health and environmental conditions. However, conventional pig behavior recognition methods are limited in their ability to effectively extract image features and analyze long sequence dependencies, ultimately reducing pig behavior recognition performance. To address these challenges, we proposes a pig behavior recognition model S_TransNeXtM which leverages both spatial and temporal information underlying the video. Specifically, an innovative backbone, named TransNeXtM, has been developed for the spatial domain. It incorporates a bio-inspired Aggregated Attention Mechanism, a Convolutional GLU, and a Mamba unit, which allows the model to capture more discriminative global and local features. For the temporal domain, the sLSTM is proposed to process sequence data by utilizing an exponential gating mechanism and a stabilizer state. This design allows the model to establish longer temporal sequence dependencies, outperforming conventional GRU and LSTM. Based on the above insights, the S_TransNeXtM enhances the performance of pig behavior recognition. Experimental results demonstrate that the proposed S_TransNeXtM model achieves the state-of-the-art performance in pig behavior recognition task. Consequently, the S_TransNeXtM attains an accuracy of 94.53%, marking an improvement of up to 11.32% over previous benchmarks.
