Subpixel Point Spread Function Estimation from Two Photographs at Different Distances
In most digital cameras, and even in high-end digital single lens reflex cameras, the acquired images are sampled at rates below the Nyquist critical rate, causing aliasing effects. This work introduces an algorithm for the subpixel estimation of the point spread function of a digital camera from aliased photographs. The numerical procedure simply uses two fronto-parallel photographs of any pla...
متن کاملRecovering the Subpixel PSF from Two Photographs at Different Distances
In most typical digital cameras, even high-end digital single lens reflex ones (dslr), the acquired images are sampled at rates below the Nyquist critical rate, causing aliasing effects. In this work we describe a new algorithm for the estimation of the point spread function (psf) of a digital camera from aliased photographs, that achieves subpixel accuracy. The procedure is based on taking two...
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...
