Science / Spiders / Convolution Product: a 2D or 3D function obtained as the result of a superposition integral. The integrand is an image or volume, and the superposed kernel is a typically short-range 'point spread function' that expresses MORE

Science / Spiders / Point-Spread Function: the kernel in the superposition integral (convolution product) that expresses the effect of a linear optical system in the formation of an image of an object. Point spread function and transfer functi MORE
