Stereoscopic image stippling

Abstract

In recent years, stereoscopy has become quite popular and has attracted the attention from many researchers, leading to numerous research studies on stereoscopic image processing, editing, and stylization. In particular, it is to our attention that, in terms of stereoscopic image stippling, one type of image stylization, there is still much room for further improvement over some existing approach, which could suffer from the effect of binocular rivalry. In this study, assuming that the input is an anaglyph or red–cyan image pair, we propose approaches to convert the input into two styles of stereoscopic image stippling, i.e., simple and hybrid, where the first one is with stipples of the same size, while the second one is with stipples of different sizes. A user study has been conducted to justify the effectiveness of our proposed approaches and improvement over some existing method.
