This paper takes HSI and HSI future as study object and carries out a number of econometric analysis by the closing price on the terminate day of every month of the HSI future contract and the corresponding closing price on the last trade day of HSI future contract.

R-value,G-value and B-value of rice color were determined through respective drawing of R-histogram,G-histogram and B-histogram,and then RGB model was converted to HSI model,so as to determine H-value,S-value an.

Color image segmentation based on HSI model owns dramatic independence,authenticity and division.

Based on realizing a self-timer system for the digital camera, this paper proposes a motion object detection method of single channel of HSI model based on background updating.

Image fusion algorithm based on HSI transform and Quantum-Behaved Particle Swarm Optimization transform;

An image fusion method based on HSI transform and Laplace decomposition is proposed for multi-focus micropaleon- tology image fusion.

Real-time classification video retrieval system based on HSI model;

A Gray image pseudo-color coding approach in HSI space based on image′s histogram;

The road scene image of RGB space was transformed into that of HSI space,a syncretic method of hue and saturation was used to extract the characteristic color area of sign in road scene,then traffic sign image was binarized,the noise was removed,and binarization target was pro.

Firstly,the original image was transferred to HSI space,and the rough locations were detected by using the edge information of the characters and the operation of the mathematical morphology;and then,the accurate region of license plate was decided by the SOM using four features proposed by this paper.
