Abstract

The invention belongs to the technical field of image data processing, and particularly relates to a threshold setting method and device in spectral similarity matching classification, and the methodcomprises the steps: obtaining a target region of interest selected from a hyperspectral image of a pre-selected object; calculating an actual similarity value between the spectral data of each pixelin the target region of interest and standard spectral data of each category in a preset spectral library; calculating a mean value and a variance of each actual similarity value; and obtaining the following threshold setting range according to the mean value and the variance of each actual similarity value. According to the method and device, reliable data reference is provided for threshold setting according to the mean value and the variance, threshold adjusting efficiency is improved, useless and irrelevant threshold setting steps are filtered out, the threshold setting process is simplified, classification efficiency is improved, and extremely high practicability is achieved.

Description

technical field [0001] The invention belongs to the technical field of image data processing, and in particular relates to a threshold value setting method and device in spectral similarity matching classification. Background technique [0002] The classification of items, such as garbage classification methods, has always been a technology that the market continues to explore and update. Commonly used classification methods on the market, such as using spectral similarity to classify, and classifying by spectral similarity. [0003] When using spectral similarity for classification, it is necessary to set a similarity comparison threshold, and use the similarity threshold to determine which classification category it belongs to. At present, when setting the threshold, the technicians set it without purpose. They check the classification effect after the threshold setting one by one, and then adjust according to the classification effect. In this way, because the setting th...
