Abstract
This paper describes the method to determine discriminative mesh zones of four categolies by tone arguments on composed color photographies which are made by malti-spectral images, and the difference of accuracy between the test field and the training field.
The accuracy of each categoly is computed from frequency of discriminative mesh zone. Some essential particulars of the result of this research are as follows.
1. The apparent accuracy on the automatic processing of the discriminative mesh zone is about 83.5% and true accuracy is about 70.3%.
2. The standard of the discrimination of the test field data is difficult to use in the training field.
3. Using the discriminative mesh zone, uneven data of each categoly does not have appraisement.
