Based on Chalkiness Vl.0, using Visual C＋＋.NET as tools, a computer image processing system ChalkinessV2.0 has been developed for the detection of chalky rice rate, chalkiness degree and grain shape for grading of the high quality rice required by the national standard NY147-88. The system is composed of modules of image preprocessing, sample identification, chalkiness distinguishing, ratio of length and width detection, statistics and analysis and results export. The system can analyze the rice chalkiness of three rice varieties： Fengyuan B...
