High spectroscopic data supervision classifying method based on information quantity dimensionality sequence

Abstract

A high spectroscopic data supervision classification method based on information quantity dimensionality sequence includes the following steps: reading the high spectrum image data of a certain region; selecting a reference spectrum from the spectrum library or selecting the training sample from images to execute wave band average acquiring reference spectrum; calculating one by one the reference spectrum and all test spectral information quantity dimensionality sequence; executing vector angle matching one by one the test spectrum with all reference spectral information quantity dimensionality sequence, and using minimum distance classification machine to classify; result binarization matching, the matching result of each series of field culture is represented by the binary images, each image only includes a series of field culture. The high spectroscopic data classification method based on information quantity dimensionality sequence introduces the information quantity dimensionality into the spectrum domain analysis, synthetizes the advantages of the all band matching and partial quantization characteristic matching, can obtain higher classification effectiveness and classification accuracy, and has important value in the high spectroscopic data classification and object identification.
