Abstract

Image classification is a well studied problem, with applications such as face recognition and natural image classification. Here, image classification is done using a neural network of spiking neurons in a feedforward heirarchy that resembles certain structures of the visual cortex. Image encoding is done first through edge detection on the image, after which an HMAX model is used to bring about degrees of scale, position, rotation, and contrast-reverse invariance. Then, a single spiking neural network layer is trained to classify the encoded image using supervised learning. Results are shown for classification of single digit handwritten numbers.
