TLDR
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.read more

Symmetry and Asymmetry from Local Phase
TL;DR: It is shown that points of symmetry and asymmetry give rise to easily recognized patterns of local phase, which can be used to construct a contrast invariant measure of symmetry that does not require any prior recognition or segmentation of objects.

TL;DR: Haidinger’s brush was used as a method of locating fixation positions on a display and showed that it is the already organized cortical representation of shape which governs fixation, rather than the peripheral input per se.
