Abstract

The disclosure relates to an image processing method and apparatus. The method comprises: according to a to-be-processed image, a first gradient map in an X direction and a second gradient map in a Ydirection of the to-be-processed image are obtained; the first gradient map is inputted into a first neural network to obtained a processed third gradient map; the second gradient map is inputted intoa second neural network to obtain a processed fourth gradient map; and according to the to-be-processed image, the third gradient map, and the fourth gradient map, minimization processing is carriedout to obtain a result image. According to the invention, with the minimized processing method, the to-be-processed image is processed by using the first neural network and the second neural network to obtain the result image, so that the image processing efficiency is improved, the face defects in the to-be-processed image are removed, and an effect of beautifying the face skin in the to-be-processed image is realized.

Description

technical field [0001] The present disclosure relates to a convolutional neural network, and in particular to an image processing method and device. Background technique [0002] CNN (convolutional neural network) is an efficient recognition method that has been developed in recent years and has attracted widespread attention. A CNN is a feed-forward neural network whose artificial neurons respond to surrounding units within a fraction of the coverage. CNN has excellent performance for large-scale image processing. With the popularization of mobile terminal camera functions, CNN is widely used in facial image beautification algorithms. [0003] In related technologies, the facial skin smoothing algorithm is the core of the beautifying algorithm, which is used to remove facial blemishes and beautify the skin. Most of the current face microdermabrasion algorithms are based on edge-preserving filtering methods, such as bilateral filtering and guided filtering. But these meth...
