Example Embodiment

[0047] In order to better understand the technical solutions of the present invention, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0048] The principle block diagram of the present invention based on neural network and morphology device for detecting weak and small infrared point targets is as follows figure 1 As shown, the filtering process is mainly divided into three parts: morphological filtering optimized by neural network, secondary threshold segmentation, and neural network classifier. The morphological filter is the beginning of the whole process, and the morphological filter can be decomposed into two basic problems of morphological operation and structural elements. When the morphological operation rules are determined, the final filtering performance of the morphological filter depends only on the selection of structural elements. The present invention uses a series of pre-obtained sample dat...

Abstract

A single frame detection method of infrared weak object based on neural network and morphology includes collecting a training sample with various point object and background first, structuring neural network for optimizing said training element and combining it with revision morphology operator to structure morphological filter for making background estimation, using primary threshold to remove of interference point then using secondary threshold and neural network classifier to remove off noise point for achieving high detection probability and high false alarm probability.

Description

technical field [0001] The invention relates to a target detection method in the technical field of image processing, in particular to a single-frame detection method for weak infrared targets based on neural network and morphology. Background technique [0002] Based on the characteristics of infrared weak and small target detection, it is difficult for traditional methods to coordinate the contradiction between algorithm complexity and calculation speed. Among them, although the feature method and the optical flow field method can extract the three-dimensional shape and depth information of the moving target well in theory, there is no more general feature selection and matching algorithm, and the basic equation of the optical flow field is only used in special cases. The occasion is established. On the other hand, single-frame detection and multi-frame detection are two basic methods of infrared weak and small moving target detection. Due to the instability of the real-...
