摘要

本文提出了一种基于背景纹理分析和多尺度距离像分析的目标检测方法.通过小波多尺度分解来提取不同分辨率下背景纹理的能量特征

并计算这些特征向量与中心向量的距离

从而得到相关的距离像

目标检测在所得的距离像上完成.在检测过程中利用红外小目标的特性

根据分析距离像统计直方图来实现检测门限的自适应选取.实验证明该方法取得了较好的效果.

Abstract

This paper presents a new small target detection approach

which is based on multi-resolution distance map and background texture analysis. Through multi-scale wavelet decomposition of background textures and local energy calculation

feature vectors of each point are obtained.According to these feature vectors

a distance map corresponding to these features can be derived

and target detection is performed on this distance map.The histogram of distance map is employed for the automatic selection of threshold value.Experiments show that this approach can achieve quite satisfactory results.
