WebIn biologically inspired neural networks, the activation function is usually an abstraction representing the rate of action potential firing in the cell. [3] In its simplest form, this function is binary —that is, either the neuron is … WebBW = im2bw (I,level) converts the grayscale image I to binary image BW, by replacing all pixels in the input image with luminance greater than level with the value 1 (white) and replacing all other pixels with the value 0 (black). This range is relative to the signal levels possible for the image's class.
