GlueStick: Robust Image Matching by Sticking Points and Lines Together

Understand

Line segments are powerful features complementary to points.

• They offer structural cues, robust to drastic viewpoint and illumination changes, and can be present even in texture-less areas.
• However, describing and matching them is more challenging compared to points due to partial occlusions, lack of texture, or repetitiveness.
• This paper introduces a new matching paradigm, where points, lines, and their descriptors are unified into a single wireframe structure.
