Interaction between High-Level and Low-Level Image Analysis for Semantic Video Object Extraction [PDF]

open access: yes, 2004
The task of extracting a semantic video object is split into two subproblems, namely, object segmentation and region segmentation. Object segmentation relies on a priori assumptions, whereas region segmentation is data-driven and can be solved in an ...
