WebYou can't really get a PSF for an extended object. The Point-Spread-Function is a parameter of your imaging system which describes the shape of the image of a putative point source. I don't have any knowledge of what your python package is intended to do, so I can't comment directly on the results.

WebThis image formation process is mathematically represented by a convolution equation: the object convolved with the imaging setup's PSF gives the acquired image. The PSF is a valid measure for the quality of an … WebFor determining an average PSF, technically we can crop out all the individual beads, align them and then average the images. Therefore, we segment the objects and determine their center of mass. # Segment objects label_image = cle.voronoi_otsu_labeling(bead_image) imshow(label_image, labels=True)
