【摘要】：非真實感繪制研究是當前計算機圖形圖像處理領域的研究熱點。國內(nèi)外各研究機構和學者對油畫、水彩畫、中國山水畫、中國書法和剪紙等藝術風格的數(shù)字模擬進行了卓有成效的研究,但對云南重彩畫的非真實感繪制研究還未見報道。論文首次選取具有濃郁民族特色和地域特色的丁紹光云南重彩畫作為研究對象,針對該畫派鮮明的中國線條畫和色彩艷麗的西方油畫特點,從白描圖繪制、特有紋理模擬等多方面展開云南重彩畫藝術風格數(shù)字模擬及合成技術研究,設計并實現(xiàn)了云南重彩畫數(shù)字合成系統(tǒng)。論文工作對中國特有藝術風格繪畫流派的風格化繪制研究是一個非常有意義的補充。研究成果可用于影視制作、圖書設計、建筑裝修設計、家庭娛樂、廣告媒體、數(shù)字娛樂等行業(yè)。論文的主要工作如下： 1、構建云南重彩畫基本圖形元素庫并設計實現(xiàn)自描圖繪制系統(tǒng) 云南重彩畫具有鮮明的中國線條畫特點,形體夸張修長的人物形象是重彩畫中最具表現(xiàn)力的部分。為表現(xiàn)該畫派線條畫特點及特有的人物造型,提出從重彩畫繪畫作品中提取基本圖形元素,構建圖形元素庫并用圖形元素進行重彩畫白描圖繪制的解決方案,這是整個云南重彩畫藝術風格模擬繪制的基礎。圖形元素分為頭發(fā)、面部、軀干、手臂和裝飾物五大類。基本圖形元素庫采取頁式和段式兩級管理模式對圖形元素進行分級管理,可以查找、添加、刪除、修改圖形元素�；谠颇现夭十嫽緢D形元素庫,設計實現(xiàn)了自描圖繪制系統(tǒng),從基本圖形元素庫中選擇用于繪圖的圖形元素,通過系統(tǒng)提供的強大的修改工具和分層繪制方式,對圖形元素進行編輯、修改、變形、組合,從而繪制出新的具有云南重彩畫風格的白描圖人物造型,為后續(xù)云南重彩畫的著色渲染奠定基礎。 2、提出云南重彩畫特有紋理生成算法 云南重彩畫具有特有的刮痕狀紋理和點塊狀紋理。在比較嘗試了多種模擬方法后,提出參數(shù)可調(diào)的LIC(Line Integral Convolution)方法模擬刮痕狀紋理,設計基于筆刷的刮痕狀紋理繪制算法,提供點狀、直線狀和曲線狀筆刷式樣,通過調(diào)節(jié)矢量場方向、噪聲場濃度改變刮痕狀紋理的樣式,達到較好的模擬效果。對點塊狀紋理提出基于多頻率LIC的填充繪制算法,通過設置不同頻率的噪聲場,生成大小粒度不同的點塊狀紋理。為表現(xiàn)點塊狀紋理中的混色效果,提出基于RGB和HSV顏色空間的混色模型。 3、提出基于CTWC的交互式局部色彩傳遞算法 基于CTWC的交互式局部色彩傳遞算法包括指數(shù)形式CTWC算法和Butterworth形式CTWC算法。論文比較了兩種算法局部色彩傳遞的效果和它們各自的參數(shù)對色彩傳遞效果的影響。指數(shù)形式CTWC算法具有色彩傳遞平滑過渡的特點。Butterworth形式CTWC算法可以通過調(diào)節(jié)濾波器的帶寬和階數(shù),控制局部色彩傳遞的效果,具有很好的色彩傳遞指向性。對多區(qū)域局部色彩傳遞,提出迭代和加權平均兩種圖像融合方式實現(xiàn)多區(qū)域局部色彩傳遞圖像融合。論文把色彩傳遞算法用于云南重彩畫風格化繪制。 4、提出按行紋理合成加速算法和Ⅱ_FFT紋理合成加速算法 論文對紋理合成加速方法進行研究,提出了按行合成算法和II_FFT(Intergral Image_Fast Fourier Transform)算法。按行合成算法將經(jīng)典的Image Quilting算法按塊合成紋理改進為按行合成紋理,先按塊合成行紋理,再一行一行合成整個紋理,由于消除了冗余誤差計算,同時采用并行計算模式,可縮短40%的合成時間。Ⅱ_FFT算法對Image Quilting算法中誤差計算方法進行改進,將原來的SSD (Sum of Squared Differences)誤差計算改為Ⅱ_FFT誤差計算,采用積分圖像和FFT快速卷積方法加速誤差計算,大大提高了合成速度,而且紋理樣本圖越大,該算法的合成速度相比Image Quilting算法提高越多。論文把紋理合成用于云南重彩畫肌膚、服飾和背景紋理的模擬。 5、設計實現(xiàn)云南重彩畫著色和渲染系統(tǒng) 論文設計實現(xiàn)了一個云南重彩畫著色和渲染系統(tǒng),對白描圖繪制系統(tǒng)繪制的白描圖進行刮痕狀紋理、點塊狀紋理的繪制,并提出基于數(shù)學形態(tài)學的中空輪廓線增強算法,設計重彩畫背景添加算法,結合色彩傳遞和紋理合成技術,實現(xiàn)云南重彩畫白描圖的著色和渲染。該系統(tǒng)包括六個功能模塊：刮痕狀紋理繪制模塊、點塊狀紋理繪制模塊、中空輪廓線增強模塊、背景添加模塊、色彩傳遞模塊和紋理合成模塊。通過各模塊的協(xié)同處理,最終得到逼真的云南重彩畫數(shù)字合成圖。
[Abstract]:The research on non photorealistic rendering is a hot topic in the field of computer graphics and image processing. The research institutions and scholars at home and abroad have done a great deal of research on the digital simulation of oil painting, watercolor, Chinese landscape painting, Chinese calligraphy and paper cutting, but the study of non realistic rendering of Yunnan heavy color painting has not been reported. Ding Shaoguang Yunnan heavy color painting with strong national characteristics and regional characteristics is selected for the first time as the research object. In view of the distinctive features of Chinese line painting and colorful western oil painting, the digital simulation and synthesis technology of Yunnan heavy color painting style are set up from many aspects, such as drawing drawing and special texture simulation. We have realized the digital synthesis system of Yunnan heavy color painting. The work of this paper is a very meaningful supplement to the style painting of Chinese unique art style painting school. The research results can be used in film and television production, book design, architectural decoration design, family entertainment, advertising media, digital entertainment and other industries. The main work of this paper is as follows :
1, build the basic graphics element library of Yunnan heavy color painting and design and implement the self tracing drawing system.
The heavy color painting in Yunnan has the distinctive features of Chinese line painting, and the figure exaggeration and slender figure is the most expressive part of the heavy color painting. In order to express the characteristics of the line painting of the school and the unique character modeling, the basic graphic elements are extracted from the painting works of the heavy color painting, the graphic element library is constructed and the graphic elements are used for the heavy color painting. The solution of drawing drawing is the basis of the simulation of the art style of Yunnan heavy color painting. The graphic elements are divided into five categories: hair, face, trunk, arm and ornament. The basic graphic element library adopts the page and segment type two level management mode to classify the graphic elements, which can be found, added, deleted, and modified. In the basic graphic elements Library of Yunnan heavy color painting, the self tracing drawing system is designed and realized. The graphic elements are selected from the basic graphic element library. Through the powerful modification tools and stratified drawing methods provided by the system, the graphic elements are edited, modified, deformed and combined, thus drawing new style with the style of Yunnan heavy color painting. The white drawing character modeling lays the foundation for the coloring and rendering of Yunnan heavy colored paintings.
2, a special texture generation algorithm for Yunnan heavy color painting is proposed
Yunnan heavy color painting has unique scratch - like texture and point - like texture. After trying a variety of simulation methods, the LIC (Line Integral Convolution) method with adjustable parameters is proposed to simulate scratch - like texture, and the scratch - like texture drawing algorithm based on brush is designed. The field direction, the noise field concentration changes the style of scratch like texture to achieve better simulation effect. The filling rendering algorithm based on multi frequency LIC is proposed for point block texture. By setting different frequencies of noise field, the block texture of different size and size is generated. The color based on RGB and HSV color is proposed. The color mixing model of space.
3, an interactive local color transfer algorithm based on CTWC is proposed.
The interactive local color transfer algorithm based on CTWC includes the index form CTWC algorithm and the Butterworth form CTWC algorithm. The paper compares the effect of the two algorithms for local color transfer and the influence of their respective parameters on the color transfer effect. The index form CTWC algorithm has the characteristic of the.Butterworth form CTWC with the smooth transition of color transfer. The algorithm can control the effect of local color transfer by adjusting the bandwidth and order of the filter, and has a good color transfer directivity. For multi region local color transfer, two kinds of image fusion methods are proposed, which are iterative and weighted average, and the color transfer algorithm is used in Yunnan heavy color painting. Stylized drawing.
4, we propose an accelerated algorithm based on line texture synthesis and an acceleration algorithm for II _FFT texture synthesis.
In this paper, the acceleration method of texture synthesis is studied. A line synthesis algorithm and a II_FFT (Intergral Image_Fast Fourier Transform) algorithm are proposed. According to the line synthesis algorithm, the classical Image Quilting algorithm is improved by the block synthetic texture to synthesize the texture according to the line. First, the line texture is synthesized according to the block, and the whole texture is synthesized by one line and one line is synthesized. Due to the elimination of the texture, the whole texture is synthesized. The calculation of redundancy error and parallel computing mode can shorten the time of 40% synthesis. II _FFT algorithm improves the calculation method of error in Image Quilting algorithm. The original SSD (Sum of Squared Differences) error calculation is changed to II _FFT error calculation, and the integral image and FFT fast convolution method are used to accelerate the calculation of error. It improves the speed of synthesis, and the larger the texture sample map, the more synthetic speed of the algorithm is improved than the Image Quilting algorithm. The paper uses texture synthesis to simulate the skin, clothing and background texture of Yunnan heavy color painting.
5, design and implement the color and rendering system of Yunnan heavy color painting
The paper designs and implements a Yunnan heavy color painting and rendering system. The white drawing drawing system draws the scratch like texture, points the block texture, and puts forward the hollow contour enhancement algorithm based on mathematical morphology, designs the background adding algorithm of the heavy color painting, and combines the color transfer and texture synthesis technology to realize the cloud. The system consists of six functional modules: scratch like texture drawing module, point block texture drawing module, hollow contour line enhancement module, background adding module, color transfer module and texture synthesis module. Through the coordination of each module, the realistic Yunnan heavy color painting digital synthesis is finally obtained. Figure.
