Computer vision is a broad field of study that encompasses different tasks (e.g., object detection, semantic segmentation, 3D reconstruction). Although computer vision is relevant to the African communities in various applications, yet computer vision research is under-explored in the continent and constructs only 0.06% of top-tier publications in the last 10 years. In this paper, our goal is to have a better understanding of the computer vision research conducted in Africa and provide pointers on whether there is equity in research or not. We do this through an empirical analysis of the African computer vision publications that are Scopus indexed. We first study the opportunities available for African institutions to publish in top-tier computer vision venues. We show that African publishing trends in top-tier venues over the years do not exhibit consistent growth. We also devise a novel way to retrieve African authors through their affiliation history to have a better understanding of their contributions in top-tier venues. Moreover, we study all computer vision publications beyond top-tier venues in different African regions to find that mainly Northern and Southern Africa are publishing in computer vision with more than 85% of African publications. Finally, we present the most recurring keywords in computer vision publications. In summary, our analysis reveals that African researchers are key contributors to African research, yet there exists multiple barriers to publish in top-tier venues and the current trend of topics published in the continent might not necessarily reflect the communities' needs. This work is part of a community based effort that is focused on improving computer vision research in Africa.
翻译:计算机视觉是一个涵盖不同任务(如目标检测、语义分割、三维重建)的广泛研究领域。尽管计算机视觉在各类应用中与非洲社区息息相关,但该领域在非洲大陆的研究仍处于探索不足的状态,近十年来仅占顶级期刊出版物总数的0.06%。本文旨在更深入地理解非洲开展的计算机视觉研究,并探讨该领域是否存在研究公平性问题。我们通过对Scopus索引的非洲计算机视觉出版物进行实证分析开展研究。首先考察非洲机构在顶级计算机视觉会议发表研究成果的可用机会,发现非洲在顶级会议的发文趋势并未呈现持续增长态势。我们创新性地通过研究者所属机构的履历信息溯源非洲作者,以更精确地评估其对顶级会议的贡献。此外,我们超越顶级会议范畴,对非洲不同区域的所有计算机视觉出版物展开研究,发现北非和南非贡献了超过85%的非洲出版物。最后,我们归纳了计算机视觉出版物中最常出现的关键词。总体而言,分析表明非洲研究者是非洲科研的核心贡献者,但仍存在多重障碍制约其在顶级会议发表成果,且当前非洲大陆发表的课题趋势未必反映社区实际需求。本研究是致力于提升非洲计算机视觉研究的社区协作计划的一部分。
