Study on Linear Appraisal of Dairy Cow's Conformation Based on Image Processing

At present, image processing technology is more commonly applied to such fields as virtual reality and biological medicine, and permeates rapidly through agricultural scientific research. The image measuring method makes dairy cow type linear appraisal , which not only reduces workload but also gets rid of the shortcoming of the manual appraisal standard changing with human and time and the disadvantage of lacking impersonal impartiality. This paper describes a linear appraisal system for analyzing dairy cow types based on image processing, which consists of hardware design, software design, realization of characters click points operating and the interactive measurement of type character parameter for dairy cow. We use NI IMAQ Vision and NI Lab Windows/CVI 6.0 to develop the system software. The central purpose of image preconditioning is to clear up noise, and we use median filtering to eliminate noise in this approach.
