Query: Semantic Change Pattern Analysis   Change detection is an important problem in vision field, especially for
aerial images. However, most works focus on traditional change detection, i.e.,
where changes happen, without considering the change type information, i.e.,
what changes happen. Although a few works have tried to apply semantic
information to traditional change detection, they either only give the label of
emerging objects without taking the change type into consideration, or set some
kinds of change subjectively without specifying semantic information. To make
use of semantic information and analyze change types comprehensively, we
propose a new task called semantic change pattern analysis for aerial images.
Given a pair of co-registered aerial images, the task requires a result
including both where and what changes happen. We then describe the metric
adopted for the task, which is clean and interpretable. We further provide the
first well-annotated aerial image dataset for this task. Extensive baseline
experiments are conducted as reference for following works. The aim of this
work is to explore high-level information based on change detection and
facilitate the development of this field with the publicly available dataset.
