摘要: 在鉛筆素描之模擬範疇中,本論文旨在探討如何利用面積資訊來定義影像中寬筆觸、中筆觸和細筆觸的繪製。做法主要如下:1. 根據影像中各種不同的灰階度加以分層。2.將亮度分層中的區塊大小做統計,區分出大面積區塊和小面積區塊。3. 依據面積區塊的大小決定筆觸的寬度,亮度資訊決定筆觸的濃淡,梯度資訊決定筆觸的方向。 本論文提出的方法以手繪素描真實筆觸呈現的角度切入,目的在於增加素描時筆觸的豐富性,使得素描時有個指標能夠選擇筆觸的種類,並佐以各種資訊來定義筆觸的參數探討其素描模擬結果。
In the field of pencil sketch, this thesis discusses how pencil strokes of various widths are to be used in sketching based on area size of homogenous intensity. When images are segmented by intensity, small areas reflect locations where details exists in the image, while large areas mostly imply no visual attraction due to the lack of intensity variation. It’s natural to use thin and fine line strokes for drawing in the former case and use thick and coarse line stroke in the latter. An automated system is implemented based on the idea aforementioned, bringing one more stroke attributes: the stroke width, to the sketching, in addition to such attributes as orientation, thickness already exploited in previous works of pencil sketching.
