Study on linear appraisal of dairy cow's conformation based on image processing

Abstract

Image processing technology is more commonly applied to such fields as virtual reality, biological medicine and permeates rapidly through agricultural scientific research. This paper described 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 Lab windows/CVI and NI IMAQ Vision to develop the system software. The key purpose of image preconditioning is to clear up noise, and we use median filtering to eliminate noise during this process. Adopting image measurement method to make dairy cow type linear appraisal is convenient and swift, precision satisfying the request, being able to replace manual appraisal. The system conduces greatly to application research of image processing technology in the type linear appraisal for dairy cows. © 2008 International Federation for Information Processing.
