Fig. 4From: Efficient and privacy-preserving image classification using homomorphic encryption and chunk-based convolutional neural networkDemonstration of the model structure performing convolutional operations on segments of the original image. The depicted convolutional network comprises one convolutional layer and two fully connected layers. The Rectified Linear Unit (ReLU) activation function is employed to introduce non-linearity, without impacting the receptive field of the convolutional layerBack to article page
