In this paper we introduce a new methodology for preprocessing images for deep learning classification purposes. We implement Einstein’s photon’s energy law as a preprocessing step before feeding images into a deep learning network. The network is designed mainly with stacked convolutional layers. Optimum architecture of the model and its regularization is tuned experimentally. We use CIFAR10 image dataset for network performance evaluation. We consider each pixel value proportion to the energy of that pixel, considering Red, Green, and Blue (RGB) wavelengths. Results indicate that preprocessing images with Einstein photon’s energy law has significant impact on accuracy of the network in image classification.
