Original picture auxiliary coloring method and device based on a neural network

Abstract

An original picture auxiliary coloring method based on a neural network comprises the steps of acquiring original line drawing manuscripts and original picture coloring manuscripts before and after coloring of a plurality of original pictures, marking coloring parameters of all subdivided areas of the original pictures, and forming original picture data samples; Using Keras to initialize a coloring neural network model, wherein the coloring neural network model adopts a VGG model; Importing an original picture data sample as a training set, and carrying out supervised learning on the coloringneural network model; and automatically coloring the input original line drawing by using the trained coloring neural network model. The invention further discloses a corresponding original picture auxiliary coloring device based on the neural network. The method has the beneficial effects that auxiliary coloring is carried out on the original picture by utilizing the neural network, so that heavycoloring work in the coloring process of the original picture is reduced, and the original picture can be conveniently and quickly manufactured and modified.

Description

technical field [0001] The invention relates to the field of computer learning, in particular to a neural network-based auxiliary coloring method and device for an original painting. Background technique [0002] Whether it is the process of video game development or animation production, a lot of original painting work is required. For example, for video game development, software developers need to design game characters, game scenes, original paintings of game props or standing paintings of main characters in the game, avatars with various expressions, etc. according to project planning. Because these original painting designs will become an important reference for future video game development, the drawing of the above original paintings often has high requirements for image quality and fineness, so that other artists can use the original paintings to supplement the actual video game development needs. Draw details of game characters, game scenes, or game props in diffe...

AI Technical Summary

Problems solved by technology

[0003] However, because the current drawing of the original painting largely depends on the experience of the artist, and it often takes a lot of time to draw, so this makes the software developer or outsourcing design company spend a lot of labor costs and time to Complete the above tasks

At the same time, since in the early stage of video game or animation production, all parties need to conduct repeated consultations and revisions on the specific design, which further slows down the development progress of related products and increases the development cost
