鉛筆素描之寬筆觸效應實驗觀察

Abstract

在鉛筆素描之模擬範疇中，本論文旨在討論寬筆觸如何以不同的濃淡、線條寬度以及筆筆之間的間距大小加以呈現之課題，並觀察其間的交互影響。做法主要分成三個步驟： 1:根據影像中各種不同的灰階度加以分層。 2：於各個分層後的灰階度設定每一筆的路徑和筆觸與筆觸間的距離。 3：設定每一筆的寬度以及濃淡度。 此論文提出的方法以手繪素描真實筆觸呈現的角度切入，並佐以各種寬筆觸特性控制來探討其素描模擬結果。

Approaches to wide stroke simulation in pencil sketch are presented in this thesis. The simulation is staged in three phases such that real taste of hand-drawn wide stroke with pencils can be mimicked. (1) Date preparation: quantization in intensity and image spatial space. (2) Building up of the paths of every stroke: determination of control paints and generation of stroke paths. (3) Final Touch: controls over the agitation on stroke width, sweeping orientation etc. are engineered for a realistic look of the final result.
