A new transform is presented that utilizes local radial symmetry to highlight points of interest within a scene and is seen to offer equal or superior performance to contemporary techniques at a relatively low-computational cost.
Abstract
A new transform is presented that utilizes local radial symmetry to highlight points of interest within a scene. Its low-computational complexity and fast runtimes makes this method well-suited for real-time vision applications. The performance of the transform is demonstrated on a wide variety of images and compared with leading techniques from the literature. Both as a facial feature detector and as a generic region of interest detector the new transform is seen to offer equal or superior performance to contemporary techniques at a relatively low-computational cost. A real-time implementation of the transform is presented running at over 60 frames per second on a standard Pentium III PC.

A fast recursive algorithm to compute local axial moments

TL;DR: In this paper, a fast algorithm to compute local axial moments used in the algorithm of discrete symmetry transform (DST) is described. But the main result of the algorithm is that the computation of the local moments is independent of the kernel size, i.e., it takes O(1) per pixel per data point (pixel).

A fast recursive algorithm for the computation of axial moments

TL;DR: The main result is that the complexity of recursive computation of axial moments becomes independent of the total number of computed moments in a given point, i.e. it is of the order O(N) where N is the data size.
