Abstract

The invention provides an image processing method and device, a server and a storage medium, and the method comprises the steps: firstly amplifying a to-be-processed initial image to obtain an amplified image, and calculating a gradient value and a gradient direction corresponding to the amplified image; further performing segmented anti-aliasing filtering on the amplified image according to the gradient direction to obtain an initial anti-aliasing filtering image; sharpening the amplified image to obtain an initial sharpened image; and finally, fusing the initial sharpening image and the initial anti-aliasing filtering image to obtain a target image after initial image processing. According to the invention, different processing is carried out on the magnified image, and the plurality of images after different processing are fused, so that the initial image is subjected to various different processing, and the sawtooth artifact phenomenon in the image is effectively reduced while the image definition is improved.

Description

technical field [0001] The present application relates to the field of image processing, in particular to an image processing method, device, server and storage medium. Background technique [0002] Traditional super-resolution reconstruction algorithms include interpolation-based super-resolution reconstruction, degradation model-based super-resolution reconstruction and learning-based super-resolution reconstruction, etc. Traditional super-resolution algorithms mainly rely on basic digital image processing techniques for reconstruction. The super-resolution algorithm based on deep learning uses the SRCNN model to first enlarge the low-resolution image by means of interpolation, and then restore it through the model. [0003] The interpolation-based method regards each pixel on the image as a point on the image plane, and uses the known pixel information to fit the unknown pixel information on the plane, usually by a predefined transformation function or interpolation kern...
