Fig. 3. (Color online) The trained deep convolutional neural network was saved as a neural network exchange package for porting implementation to the Internet of Things and embedded systems. The overall structure was visualized by reading the neural network exchange format. The input tensor of the neural network has dimensions [24, 3, 1068, 712], where 24 is the batch size, 3 is the RGB channel, and 1068 × 712 is the image resolution. The output matrix of the neural network has dimensions [24, 46] where 46 is the number of classifications.
