【摘要】：动漫产业现已经成为以动画卡通、网络游戏、手机游戏、多媒体产品为代表的新兴产业,并被视为21世纪创意经济中最有希望的朝阳产业。发展动漫产业,必须要有所侧重,重点发展可以更好地集中和利用资源。目前,面对家庭休闲娱乐的动画制作软件还很缺乏,本平台主要就是针对普通用户对视频进行风格化处理。已有商业软件,例如Photoshop、Premiere Pro主要是面向专业美工人员,通过复杂的编辑操作,形成各种艺术特效。本平台主要研究成果是建立“一键式卡通特效”模型。通过该模型,用户只需输入真实图像或视频,并指定相应的特效类型,系统就能够输出具有特定风格的艺术化效果。论文主要工作包括: (1)提出一种采用灰度合成的图像素描效果快速生成算法,实现真实感图像的草图艺术化生成。不同于已有算法只是利用经典的边缘检测方法来提取图像的边缘特征,通过灰度信息分布来控制素描图像的细节特征,通过灰度合成得到图像边缘特征的加强和柔化,形成素描效果。 (2)建立卡通风格的色彩模型,描述了如何对原始图像进行颜色空间分析,去除颜色细节特征,减少颜色分量,实现对颜色的抽象化。采用非线性滤波算法,该滤波技术本质上还是一种颜色空间聚类模型。采用非线性滤波的一个典型优势是该滤波技术可以有效地保持轮廓特征。通过非线性滤波,不仅可以有效地消除不重要的颜色信息,同时能够保持原始图像的轮廓等重要特征。从而达到色彩卡通化效果。在上述算法、模型研究的基础上,论文采用VC开发工具,结合OpenCV图像处理包,开发了图像风格特效原型系统,并对上述算法有效性进行验证。
[Abstract]:Animation industry has become a new industry represented by cartoon, online games, mobile phone games and multimedia products, and is regarded as the most promising sunrise industry in the creative economy of the 21st century. The development of animation industry, must be focused on, focus on development can better concentrate and use resources. At present, there is still a lack of animation software in the face of family leisure and entertainment. This platform is mainly aimed at ordinary users to stylize the video. Existing commercial software, such as Photoshop,Premiere Pro, is mainly for professional art workers, through complex editing operations to form a variety of artistic effects. The main research result of this platform is to establish a one-button cartoon special effect model. Through this model, the system can output the artistic effect with a specific style by simply inputting the real image or video and specifying the corresponding special effect type. The main work of this paper is as follows: (1) A fast image sketch generation algorithm based on gray scale synthesis is proposed to realize the artistic sketch generation of realistic images. Different from the existing algorithms, the classical edge detection method is used to extract the edge features of the image, the detailed features of the sketch image are controlled by the distribution of gray information, and the edge features of the image are enhanced and softened by gray level synthesis. (2) establish the color model of cartoon style, describe how to analyze the color space of the original image, remove the color detail feature, reduce the color component, and realize the color abstraction. Using nonlinear filtering algorithm, the filtering technique is essentially a color space clustering model. A typical advantage of nonlinear filtering is that it can effectively preserve contour features. Through nonlinear filtering, not only the unimportant color information can be effectively eliminated, but also the important features such as the contour of the original image can be preserved. In order to achieve the effect of color card. On the basis of the above algorithm and model research, this paper uses VC development tools, combined with OpenCV image processing package, to develop the image style special effect prototype system, and to verify the effectiveness of the above algorithm.
