摘要: 於鉛筆素描之模擬範疇中,本論文旨在探討如何處理影像中非描繪重點區域之筆觸模擬與相關處理。主要構想在於就影像中背景及大面積區域以粗疏而淡化之筆觸描繪,使整體視覺效果更為生動。本論文方法主要步驟如下:1. 根據灰階亮度曲線動態分層。2.根據分層結果模擬粗細方向不同的筆觸。3.依據亮度靜態分層結果得到的區塊資訊來做筆觸的分配和相關處理。4.再加入輪廓強化圖和紙質效果。 本論文實作系統除了省去了人工參數的設定,並以真實手繪的角度切入,增加筆觸的變化與豐富度和非重點描繪區域之處理,使模擬出來的效果更具有手繪素描之風格。
In the field of pencil sketch simulation, this thesis addresses how various pencil strokes are to be used in sketching and how the subject-irrelevant areas are to be rendered, particularly the latter issue. Regarding the rendering of subject-irrelevant areas, criteria are proposed to identify large regions in the image of low intensity contrast wherein specifically devised wide, sparsed and light strokes are deployed. An automated system is implemented accordingly, and the final outcome is considered to be visually satisfactory in mimicking hand-drawn pencil sketching .
