Nettet8. okt. 2024 · The line spread function (LSF) is derived by averaging the pixel intensities, the point spread function (PSF) values, surrounding the wire. The x and y-axis PSF values are averaged and symmetrized, and then both directions are averaged to create the LSF plot.

Nettet1. des. 2024 · PSF (point spread function) for an image (2D) I'm new in image analysis (with Python) and I would like to apply the richardson_lucy deconvolution (from skimage) on my data (CT scans). For this reason, I estimated the PSF in "number of voxels" by means of a specific software. Its value is roughly 6.73 voxels, but I don't know how to … NettetThe line spread function (the image of an infinitely narrow line) is an integration over one variable of the point spread function. In general, the input may be at some arbitrary angle to the y - axis and hence ℓ will also be a function of that angle. For the special case in which the point spread function is rotationally symmetrical, i.e. NettetFor the first definition of the MTF you should notice that the line-spread-function is the gradient of the edge-spread-function perpendicular to the edge. Since your edge is rotated relative to the detector you have to correct for that (or do some additional work to squeeze out sub-pixel resolution for the ESF). cr0 6be
