For the rapid and accurate identification of cow reproduction and healthy behavior from mass surveillance video,in this study,400 head of young cows and lactating cows were taken as the research object and analyzed cow behavior from the dairy activity area and milk hall *** method of object recognition based on image entropy was proposed,aiming at the identification of motional cow object behavior against a complex *** a minimum bounding box and contour mapping were used for the real-time capture of rutting span behavior and hoof or back ***,by combining the continuous image characteristics and movement of cows for 7 d,the method could quickly distinguish abnormal behavior of dairy cows from healthy reproduction,improving the accuracy of the identification of characteristics of dairy *** behavior recognition based on image analysis and activities was proposed to capture abnormal behavior that has harmful effects on healthy reproduction and to improve the accuracy of cow behavior *** experimental results showed that,through target detection,classification and recognition,the recognition rates of hoof disease and heat in the reproduction and health of dairy cows were greater than 80%,and the false negative rates of oestrus and hoof disease were 3.28%and 5.32%,*** method can enhance the real-time monitoring of cows,save time and improve the management efficiency of large-scale farming.

＜正＞This paper aims to realize a distributed intelligent video analysis system based on TI DSP chip *** new system we proposed in this paper provides users with fast,precise and smart video analysis *** system collects real time field data via analog cameras and IP cameras based on Network or Wireless *** image data then is transmitted to embedded high speed DSP real-time image processing board,where target,including person,object and vehicle,is extracted from background and compared with prescribed *** can freely set virtual alarm line,alarm region and violation behaviors through rule setting *** chip DM642 then analyze video images timely,and detect *** segmentation, feature abstraction,alarm and automatic tracking of multi-channel and multi-camera are implemented at the same time in this system. This system can be applied in many areas,for example,security *** it has great potential in applications with very high commercial values.
