Webedgetaper. Taper the discontinuities along the image edges. Syntax. J = edgetaper(I,PSF) Description. J = edgetaper(I,PSF) blurs the edges of the input image, I, using the point spread function, PSF.The output image, J, is the weighted sum of the original image, I, and its blurred version.The weighting array, determined by the autocorrelation function of PSF, … http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/images/fspecial.html

WebTo center the PSF at the origin, otf2psf circularly shifts the values of the output array down (or to the right) until the (1,1) element reaches the central position, then it crops the result to match dimensions specified by sz. This function is used in image convolution and deconvolution when the operations involve the FFT. http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/images/fspecial.html

Webh = fspecial (type) creates a two-dimensional filter h of the specified type. Some of the filter types have optional additional parameters, shown in the following syntaxes. fspecial returns h as a correlation kernel, which is the appropriate form to use with imfilter. h = fspecial ('average',hsize) returns an averaging filter h of size hsize. fast forward eventsWebFirst, create a point-spread function, PSF, by using the fspecial function and specifying linear motion across 21 pixels at an angle of 11 degrees.
