The Cow Posture Recognition Research Based on Machine Vision
Abstract: In order to detect the cow abnormal posture and warn automatically for digital cultivation, the monitoring video of 2 days in dairy farm was taken as the research object in this essay. Images of standing and lying cows including 8 types of postures were captured from the video and the cow posture image library was established. Firstly, object of cow was segmented from image by two ways which are Marker-Controlled Watershed segmentation method and Support Vector Machine segmentation method. Then, the Hu invariant moments were extracted for the cow object. Finally, the cow postures were classified with three methods which are Support Vector Machine, supervised learning neural network GRNN and PNN, unsupervised learning neural network SOFM. In the experiment, 74 cow posture images were identified in the image library, and 62 correct ones were identified, with a recognition rate of 83.78%, which achieved a satisfactory recognition effect.
