Parsing Objects at a Finer Granularity:A Survey

扫码查看
Fine-grained visual parsing,including fine-grained part segmentation and fine-grained object recognition,has attracted considerable critical attention due to its importance in many real-world applications,e.g.,agriculture,remote sensing,and space techno-logies.Predominant research efforts tackle these fine-grained sub-tasks following different paradigms,while the inherent relations between these tasks are neglected.Moreover,given most of the research remains fragmented,we conduct an in-depth study of the ad-vanced work from a new perspective of learning the part relationship.In this perspective,we first consolidate recent research and bench-mark syntheses with new taxonomies.Based on this consolidation,we revisit the universal challenges in fine-grained part segmentation and recognition tasks and propose new solutions by part relationship learning for these important challenges.Furthermore,we conclude several promising lines of research in fine-grained visual parsing for future research.
