Accurate stereo matching using pixel normalized cross correlation in time domain

Accurate stereo matching using pixel normalized cross correlation in time domain

This paper proposes a novel method for stereo matching which is based on combination of active and passive stereo 3D reconstruction approaches. A laser line is used to scan the reconstructed scene and a stereo camera pair is used for the image acquisition. Each image pixel is scanned at a specific scan time so that the intensity time patterns of the correspondent pixels are highly correlated. T...

Normalized Cross Correlation for Stereo Matching Under Varying Illumination

One of the difficulties in obtaining a dense and accurate disparity map through stereo matching is the presence of radiometric variation in the two images used in this process.It is commonly assumed that in stereo matching, the corresponding pixels have similar pixel values. But the presence of this variation causes the regular methods to produce erroneous results. In this paper, we use the con...

Template Matching using Fast Normalized Cross Correlation

In this paper we present an algorithm for fast calculation of the normalized cross correlation NCC and its applica tion to the problem of template matching Given a template t whose position is to be determined in an image f the basic idea of the algorithm is to represent the template for which the normalized cross correlation is calculated as a sum of rectangular basis functions Then the correl...

Sub-pixel precision image matching for measuring surface displacements on mass movements using normalized cross-correlation

Multi-Wavelet based Stereo Correspondence Matching using Covariance and Enhanced Normalized Cross Correlation

This paper presents the application of covariance and Enhanced Normalized Cross Correlation (ENCC) algorithm in a multi-wavelet based stereo correspondence matching. A balanced multi-wavelet transform is applied to a pair of stereo images de-correlating each input image into its multiwavelet’s sub-bands. The resulting four multi-wavelet basebands of each view are then used to calculate the disp...
