Embodiment Construction

[0032]In order to facilitate understanding of the present invention, at first the theoretical basis of the present invention is provided:

[0033] One of the important functions of the human immune system is to remove foreign objects by producing antibodies. Foreign objects can be microorganisms (bacteria, viruses, etc.), abnormal blood cells, transplanted organs, etc., which are called antigens. The basic building blocks of the immune system are lymphocytes, or white blood cells. These special cells can be mainly divided into two categories: B cells and T cells. Both types of cells have their own unique ecology and produce many Y-shaped antibodies from their surfaces to kill antigens.

[0034] In order to explain the formation mechanism of antibodies, some scholars first proposed the template theory, and later put forward the side chain theory, but none of them can reasonably explain the formation mechanism of antibodies. The mechanism of antibody formation was not explaine...

Abstract

The invention is a remote sensed image artificial immunity non-monitoring classifying method, characterized in: (1) opening to-be-classified remote sensed image and inputting algorithm parameters; 2) selecting various initial antibody populations and memory antibodies non-monitoring classified and storing them into various antibody arrays and memory antibody arrays; 3) making artificial immunity system training on image antigens until the training of the whole image is finished; 4) judging whether to meet training stop condition: if not, starting the next iteration from the step 3); otherwise ending the artificial immunity non-monitoring classification and outputting classification result. And the method inherits biological attributes of the bio-immunity system, having self-organizing, self-learning, self- recognizing and self-memorizing abilities and high intelligence, and high executing efficiency in practice, applying to non-monitoring classification of multi-spectrum, and high-spectrum remote sensed images and able to effectively improve the accuracy of remote sensed image non-monitoring classification.

Description

technical field [0001] The invention belongs to the technical field of remote sensing image processing, in particular to a non-supervised classification method for remote sensing images based on an artificial immune system. Background technique [0002] The unsupervised classification of remote sensing images means that people do not impose any prior knowledge on the classification process in advance, and only blindly classify them naturally according to the distribution law of the spectral characteristics of remote sensing image features. The result of its classification is only to distinguish different categories, and the attributes of the categories are not determined. The attributes are determined after analyzing the spectral response curves of various types and comparing them with field investigations. The traditional unsupervised classification of remote sensing images mainly uses K-means algorithm or ISODATA algorithm. [0003] The basic idea of ​​the K-means algorit...
