A Model for Resolution Enhancement (Hyperacuity) in Sensory Representation
نویسندگان
چکیده
Heiligenberg (1987) recently proposed a model to explain how sensory maps could enhance resolution through orderly arrangement of broadly tuned receptors. We have extended this model to the general case of polynomial weighting schemes and proved that the response function is also a polynomial of the same order. We further demonstrated that the Hermitian polynomials are eigenfunctions of the system. Finally we suggested a biologically plausible mechanism for sensory representation of external stimuli with resolution far exceeding the inter-receptor separation.

A Deep Model for Super-resolution Enhancement from a Single Image
This study presents a method to reconstruct a high-resolution image using a deep convolution neural network. We propose a deep model, entitled Deep Block Super Resolution (DBSR), by fusing the output features of a deep convolutional network and a shallow convolutional network. In this way, our model benefits from high frequency and low frequency features extracted from deep and shallow networks...
متن کاملTactile hyperacuity for robotics
Hyperacuity is a general aspect of animal perception that exploits spatially overlapping sensory receptive fields to perceive at finer acuity than the sensor resolution. Following a recent demonstration of hyperacuity in robot touch, we present a detailed and systematic analysis of localization acuity for both a biomimetic fingertip and a region of tactile skin. We identify three key factors fo...

Objective Sensory processing refers to reception, adjustment, and integration of sensory information sequentially and generates adaptive responses. People need to have appropriate sensory processing abilities for functioning adequately in the environment and be able to participate in activities of daily living. Dunn's sensory processing model consists of two constructions. The first constructio...
متن کاملPseudo Zernike Moment-based Multi-frame Super Resolution
The goal of multi-frame Super Resolution (SR) is to fuse multiple Low Resolution (LR) images to produce one High Resolution (HR) image. The major challenge of classic SR approaches is accurate motion estimation between the frames. To handle this challenge, fuzzy motion estimation method has been proposed that replaces value of each pixel using the weighted averaging all its neighboring pixels i...
متن کاملInfant hyperacuity for radial deformation.
PURPOSE Poor response rates and/or the confounding of motion and offset responses make it difficult to interpret results of previous studies of infant hyperacuity. The aim of the present study was to design a protocol that overcomes these limitations and to investigate the normal maturation of hyperacuity. METHODS Hyperacuity of 31 healthy term infants aged 4 to 12 months was measured using r...
