Towards quantum template matching
We consider the problem of locating a template as a subimage of a larger image. Computing the maxima of the correlation function solves this problem classically. Since the correlation can be calculated with the Fourier transform this problem is a good candidate for a superior quantum algorithmic solution. We outline how such an algorithm would work.
متن کاملEvaluation of Similarity Measures for Template Matching
Image matching is a critical process in various photogrammetry, computer vision and remote sensing applications such as image registration, 3D model reconstruction, change detection, image fusion, pattern recognition, autonomous navigation, and digital elevation model (DEM) generation and orientation. The primary goal of the image matching process is to establish the correspondence between two ...
متن کاملFast Template Matching
Although it is well known that cross correlation can be efficiently implemented in the transform domain, the normalized form of cross correlation preferred for template matching applications does not have a simple frequency domain expression. Normalized cross correlation is usually computed in the spatial domain for this reason. This short paper shows that unnormalized cross correlation can be ...
متن کاملCompression-Based Template Matching
Textual image compression is a method of both lossy and lossless image compression that is particularly effective for images containing repeated sub-images, notably pages of text (Mohiuddin et al., 1984; Witten et al., 1992). The process comprises three main steps: Extracting all the characters from an image; Building a library that contains one representative for each character class; Compress...
متن کاملAveraged Template Matching Equations
By exploiting an analogy with averaging procedures in fluid dynamics, we present a set of averaged template matching equations. These equations are analogs of the exact template matching equations that retain all the geometric properties associated with the diffeomorphism group, and which are expected to average out small scale features and so should, as in hydrodynamics, be more computationall...
