Title: IMAGE UPSCALING SYSTEM, TRAINING METHOD THEREFOR, AND IMAGE UPSCALING METHOD
Abstract:
An image upscaling system, a training method therefor, and an image upscaling method. The image upscaling system may comprise at least two convolutional neural network modules and at least one combiner. The convolutional neural network modules and the combiner are alternately connected to each other. A first convolutional neural network module may receive an input image and a corresponding supplemental image, generate a first number of feature images, and output same to the next combiner connected to the first convolutional neural network module. Another convolutional neural network module may receive an output image and a corresponding supplemental image from the previous combiner, generate a second number of feature images, and output same to the next combiner connected to the convolutional neural network module, or output same from the image upscaling system. The combiner may synthesize every n*n feature images in received feature images into one feature image, and output the resultant third number of feature images to the next convolutional neural network module connected to the combiner, or output same from the image upscaling system.
