Title: FILTER REUSING MECHANISM FOR CONSTRUCTING ROBUST DEEP CONVOLUTIONAL NEURAL NETWORK
Abstract:
An apparatus and method, and the method includes: generating feature maps for a first convolutional layer of a convolutional neural network based on a region of an image to be evaluated and a learned filter from the first convolutional layer (406); generating feature maps for one or more subsequent convolutional layers of the convolutional neural network based on the feature maps of a prior convolutional layer, a learned filter for the prior convolutional layer and a learned filter for the subsequent convolutional layer (408); detecting a presence of an object of interest in the region of the image based on the generated feature maps of the first and one or more subsequent convolutional layers (410).
