1. A processor-implemented method of generating feature data, the method comprising:
receiving an input image;
generating N binary images from the input image, wherein N is the number of bits per pixel of the input image, wherein N is an integer equal to or greater than 2; and
generating, using at least one neural network, feature data corresponding to the input image from the N binary images,
wherein the generating N binary images from the input image comprises:
generating each of the N binary images for each bit value level from a highest bit to a lowest bit of the binary bit values of a pixel value of the input image.
