| 摘 要： | 仿射不变量特征提取方法已成为计算机视觉研究的重点课题之一.本文提出一种归一化直方图算法,该算法基于多尺度自卷积变换中密度函数的概念,研究归一化密度函数的方法,构建了从目标图像中提取直方图仿射不变量特征提取算法,实现了基于多尺度自卷积归一化直方图的仿射不变量模式识别.仿真实验表明,本算法对一定范围内的噪声,局部遮挡,照度及视角变化具有良好的适应性,特别是在多种环境下,其识别率优于多尺度自卷积和基于多尺度自卷积的其它直方图算法.

| Abstract: | Affine invariant feature extraction methods have been one of the key issues of computer vision research.This paper proposes a normalized histogram algorithm based on the density function of multi-scale autoconvolution transform and researches the normalization method of the density function,and constructs a method to extract the histogram affine invariant feature,and implements affine invariant pattern recognition based on multi-scale autoconvolution normalized histograms.Simulation results show that this a... |
