The accurate identification of various postures in the daily life of piglets that are directly reflected by their skeleton morphology is necessary to study the behavioral characteristics of ***,this study proposed a novel approach for the skeleton extraction and pose estimation of ***,an improved Zhang-Suen(ZS)thinning algorithm based on morphology was used to establish the chain code mechanism of the burr and the redundant information deletion templates to achieve a single-pixel width extraction of pig ***,body nodes were extracted on the basis of the improved DeepLabCut(DLC)algorithm,and a part affinity field(PAF)was added to realize the connection of body nodes,and consequently,construct a database of pig behavior and ***,a support vector machine was used for pose matching to recognize the main behavior of *** this study,14000 images of piglets with different types of behavior were used in posture recognition *** showed that the improved algorithm based on ZS-DLC-PAF achieved the best thinning rate compared with those of distance transformation,medial axis transformation,morphology refinement,and the traditional ZS *** node tracking accuracy reached 85.08%,and the pressure test could accurately detect up to 35 nodes of 5 *** average accuracy of posture matching was 89.60%.This study not only realized the single-pixel extraction of piglets’skeletons but also the connection among the different behavior body nodes of individual sows and multiple ***,this study established a database of pig posture behavior,which provides a reference for studying animal behavior identification and classification and anomaly detection.
