Sub-pixel Precision Image Matching for Displacement Measurement of Mass Movements Using Normalised Cross-correlation

This study evaluates the performance of two fundamentally different approaches to achieve sub-pixel precision of normalised crosscorrelation when measuring surface displacements on mass movements from repeat optical images. In the first approach, image intensities are interpolated to a desired sub-pixel resolution using a bi-cubic interpolation scheme prior to the actual displacement matching. ...

Gradient Cross Correlation for Sub-pixel Matching

Sub-pixel matching is one of the key components for image registration and image fusion. Ideally, image matching should allow for offsets in the target image, and for scaling and rotation. Offsets allow for sub-pixel shifts in the two images, while scaling is necessary when matching images from different sensors or images taken from different distances using the same camera. Rotation allows for...

Image sequence enhancement using sub-pixel displacements

Given a sequence of images taken from a moving camera, they are registered with sub-pixel accuracy in respect to translation and rotation. The sub-pixel registration enables image enhancement in respect to improved resolution and noise cleaning. Both the registration and the enhancement procedures are described. The methods are particulary useful for image sequences taken from an aircraft or sa...

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...
