Vector Scaffolding: Inter-Scale Orchestration for Differentiable Image Vectorization
Jaerin Lee, Kanggeon Lee, Kyoung Mu Lee
Differentiable vector graphics have enabled powerful gradient-based optimization of vector primitives directly from raster images. However, existing frameworks formulate this as a…
Auto-regressive transformation for image alignment
Kanggeon Lee, Soochahn Lee, Kyoung Mu Lee
Existing methods for image alignment struggle in cases involving feature-sparse regions, extreme scale and field-of-view differences, and large deformations, often resulting in sub…
Particle Diffusion Matching: Random Walk Correspondence Search for the Alignment of Standard and Ultra-Widefield Fundus Images
Kanggeon Lee, Soochahn Lee, Kyoung Mu Lee
We propose a robust alignment technique for Standard Fundus Images (SFIs) and Ultra-Widefield Fundus Images (UWFIs), which are challenging to align due to differences in scale, app…
Active Diffusion Matching: Score-based Iterative Alignment of Cross-Modal Retinal Images
Kanggeon Lee, Su Jeong Song, Soochahn Lee +1
Objective: The study aims to address the challenge of aligning Standard Fundus Images (SFIs) and Ultra-Widefield Fundus Images (UWFIs), which is difficult due to their substantial…
MatRes: Zero-Shot Test-Time Model Adaptation for Simultaneous Matching and Restoration
Kanggeon Lee, Soochahn Lee, Kyoung Mu Lee
Real-world image pairs often exhibit both severe degradations and large viewpoint changes, making image restoration and geometric matching mutually interfering tasks when treated i…
