GIM: Learning Generalizable Image Matcher From Internet Videos

ICLR 2024spotlight

Image matching is a fundamental computer vision problem. While learning-based methods achieve state-of-the-art performance on existing benchmarks, they generalize poorly to in-the-wild images. Such methods typically need to train separate models for different scene types (e.g., indoor vs. outdoor) a…

Harmonic Retrieval for Non-Circular Coherent Signals via Double Decoupled Atomic Norm Minimization

ICASSP 2024accepted

This paper studies super-resolution harmonic retrieval for strictly non-circular coherent signals. We develop gridless sparse representations of both their covariance and pseudo-covariance matrices over a common matrix-form atom set. This enables the decoupled atomic norm minimization (D-ANM) techni…
