Gauss-Laguerre Keypoints Extraction Using Fast Hermite Projection Method

Image Analysis and Recognition Lecture Notes in Computer Science Volume pp

Oct 2011

Keypoints detection and descriptors construction method based on multiscale Gauss-Laguerre circular harmonic functions expansions is considered. Its efficient acceleration procedure is introduced. Two acceleration ideas are used. The first idea is based on the interconnection between Gauss-Laguerre circular harmonic functions system and 2D Hermite functions system. The further acceleration is based on the original fast Hermite projection method. The comparison tests with SIFT algorithm were performed. The proposed method can be additionally enhanced and optimized. Nevertheless even preliminary investigation showed promising results.

Robust Matching of Aerial Images with Low Overlap

Photogrammetric Computer Vision and Image Analysis

Sep 2010

This paper addresses the problem of aerial image matching. We analyze existing approaches to this problem and show that, though the modern algorithms cope with the task quite well, their results are deteriorated in case of low overlap and significant rotation angle between the images. A two-stage feature-based image matching scheme is presented. It is shown that preliminary stage of simplified (shift-rotation) model estimation is crucial in case of low overlap and influences significantly the whole matching scheme. We introduce a novel method of shift-rotation model estimation, based on the voting procedure in parameter space, which allows finding the correct model in case of extremely difficult input data (overlap area is less than 10%) wi

Atomic-emission spectroscopy data smoothening

Inorganic Materials December Volume Issue pp

Jan 2009

Noise suppression in experimental functions obtained by atomic-emission spectrometry is considered. The main features of such data are the large number of simultaneously measured parameters with individual noise levels as well as the necessity to keep the amount of concentrations of measured substances. The proposed two-parameter regularizing method of noise elimination makes it possible to solve this task efficiently. The method can be applied to a wide variety of experimental data smoothening.
