The Conversion Relation Between RGB Color Space and Chlorophyll Content Measured by the Routine Method

摘要

The chlorophyll content of vegetable directly affects product's appearance quality, thereby decides its merchandise value. This paper takes example for spinach, based on using BP neural network to realize the conversion relation between RGB color space of computer visual system and chlorophyll content measured by the routine method, the measuring method of chlorophyll content with computer visual system is put forward. This method takes on the characteristic of handling simple, nondestructive wound, fast measurement speed and low cost etc, and accordingly quests for a new approach in place of the chemistry analysis method.
