Space-variant (or foveating) vision architectures are of importance in both machine and biological vision. In this paper, we focus on a particular space-variant map, the log-polar map, which approximates the primate visual map, and which has been applied in machine vision by a number of investigators during the past two decades. Associated with the log-polar map, we define a new linear integral transform, which we call the exponential chirp transform. This transform provides frequency domain…

TLDR
A Lie group approach is used to derive a kernel which provides a quasi-shift (i.e. approximate shift) invariant template matching capability, under normal convolution in the distorted (range) coordinates of the non-uniform mapping.
Real-time restoration of images degraded by uniform motion blur in foveal active vision systems
TLDR
This work shows that it is possible to achieve full-frame image de-blur at frame rate on a standard "PC" platform, and suggests that these methods are relevant to applications in mobile image processing platforms in which real-time motion deblur is important, and for which it is not desirable to use extensive or custom fabricated hardware.
Real-time Motion Blur Estimation and Restoration in Foveal Active Vision Systems
TLDR
This work shows that the fast exponential chirp transform provides a simple algorithm with low spatial complexity for full frame, real-time image restoration of foveal imagery.
The Local Structure of Space-variant Images
Image processing in catadioptric planes: spatiotemporal derivatives and optical flow computation
Images produced by catadioptric sensors contain a significant amount of radial distortion and variation in inherent scale. Blind application of conventional shift-invariant operators or optical flow
The Log-polar Image Representation in Pattern Recognition Tasks
TLDR
This paper is a review of works about the use of the log-polar image model for pattern recognition purposes, and two approaches addressing the estimation of translation, rotation and scaling are compared.
Geometric Analysis of the Conformal Camera for Intermediate-Level Vision and Perisaccadic Perception
A binocular system developed by the author in terms of projective Fourier transform (PFT) of the conformal camera, which numerically integrates the head, eyes, and visual cortex, is used to process
A space-variant model for motion interpretation across the visual field.
TLDR
A neural model for the estimation of the focus of radial motion (FRM) at different retinal locations is implemented and its results are compared by comparing its results with respect to the precision with which human observers can estimate the FRM in naturalistic motion stimuli, validating the model's potential application to neuromimetic robotic architectures.
Near-optimal combination of disparity across a log-polar scaled visual field
TLDR
The notion that the foveated, binocular visual system has been moulded by the statistics of the authors' visual environment is supported, as it is shown that small changes in disparity-defined depth are detected best in central vision, whereas peripheral vision best captures the coarser structure of the environment.

TLDR
Use of the LT of the image data as a preprocessing step permits the creation of a single Wiener filter optimized for use at all scales of magnification, and application to a problem of character recognition and matched filtering is proposed.

A new method to match a 2D image to a translated, rotated and scaled reference image using symmetric phase-only matched filtering to the FMI descriptors, which guarantees high discriminating power and excellent robustness in the presence of noise.
Cortical Anatomy, Size Invariance, and Spatial Frequency Analysis
TLDR
It is shown that the architecture of the retinostriate map may provide an example of computational anatomy in vision, such that the spatial representation of a stimulus in the brain may be of direct functional significance to perception, and to the nature of certain visual illusions.
Coherent optical implementation of 1-D Mellin transforms.
TLDR
A coherent optical technique for Mellin transforms is described here in which signals may be processed in real time to provide scale invariant correlations and the parameterization on time uncertainty is provided for automatically by utilizing an acoustooptic spatial light modulator.
