Revisiting Single Image Reflection Removal In the Wild

This research focuses on the issue of single-image reflection removal (SIRR)
in real-world conditions, examining it from two angles: the collection pipeline
of real reflection pairs and the perception of real reflection locations. We
devise an advanced reflection collection pipeline that is highly adaptable to a
wide range of real-world reflection scenarios and incurs reduced costs in
collecting large-scale aligned reflection pairs. In the process, we develop a
large-scale, high-quality reflection dataset named Reflection Removal in the
Wild (RRW). RRW contains over 14,950 high-resolution real-world reflection
pairs, a dataset forty-five times larger than its predecessors. Regarding
perception of reflection locations, we identify that numerous virtual
reflection objects visible in reflection images are not present in the
corresponding ground-truth images. This observation, drawn from the aligned
pairs, leads us to conceive the Maximum Reflection Filter (MaxRF). The MaxRF
could accurately and explicitly characterize reflection locations from pairs of
images. Building upon this, we design a reflection location-aware cascaded
framework, specifically tailored for SIRR. Powered by these innovative
techniques, our solution achieves superior performance than current leading
methods across multiple real-world benchmarks. Codes and datasets will be
publicly available.
