Study on HSI color model-based fruit quailty evaluation

In order to evaluate the qualities of fruits, a new method based on HSI color model was proposed in this paper. An image of fruits was taken and transferred from the RGB color model to the HSI color model. Its simplified histogram of hue H was calculated, which was used as the input of a designed BP network. The output of the BP network was the description of evaluated quality of the fruits. After training, the quality of fruits was identified by the BP network according to the simplified histogram of H of their colored image. Experiments were conducted with satisfied results to show the feasibility and usefulness of the proposed method of fruit quality evaluation.
