Non-parametric Sub-pixel Local Point Spread Function Estimation
This work presents an algorithm for the local subpixel estimation of the Point Spread Function (PSF) that models the intrinsic camera blur. For this purpose, the Bernoulli(0.5) random noise calibration pattern introduced in a previous article [1] is used. This leads to a well-posed near-optimal accurate estimation. First the pattern position and its illumination conditions are accurately estima...
متن کاملPoint Spread Function Estimation for a Terahertz Imaging System
We present a method for estimating the point spread function of a terahertz imaging system designed to operate in reflection mode. The method is based on imaging phantoms with known geometry, which have patterns with sharp edges at all orientations. The point spread functions are obtained by a deconvolution technique in the Fourier domain. We validate our results by using the estimated point sp...
متن کاملEstimation of the ocular point spread function by retina modeling.
Retinal imaging often suffers from blurring aberrations. With knowledge of the blurring point spread function (PSF), better images can be reconstructed by deconvolution techniques. We demonstrate a method to enhance the contrast of retinal cells by estimating the ocular PSF. This is done by finding the cells' positions and their intensity distributions and using these as a model for the image. ...
متن کاملAutomated Image-Adaptive Point-Spread Function Estimation for Biological Imaging
Why are we interested in image restoration? The idea is to visualise the hearing organ in near-intact preparations with confocal microscopy. This is often made under image conditions far from optimal and this is where image restoration can be very useful, allowing one to increase the signal-to-noise ratio of the image by denoising and to increase their resolution by deconvolution. The problem s...
متن کاملNONPARAMETRIC ESTIMATION OF A POINT-SPREAD FUNCTION IN MULTIVARIATE PROBLEMS Short Title: Estimating a point-spread function
The removal of blur from a signal, in the presence of noise, is readily accomplished if the blur can be described in precise mathematical terms. However, there is growing interest in problems where the extent of blur is known only approximately, for example in terms of a blur function which depends on unknown parameters that must be computed from data. More challenging still is the case where n...
