CRFT: Consistent-Recurrent Feature Flow Transformer for Cross-Modal Image Registration

CVPR 2026

We present Consistent-Recurrent Feature Flow Transformer (CRFT), a unified coarse-to-fine framework based on feature flow learning for robust cross-modal image registration. CRFT learns a modality-independent feature flow representation within a transformer-based architecture that jointly performs f

LIRA: Inferring Segmentation in Large Multi-modal Models with Local Interleaved Region Assistance

ICCV 2025poster

While large multi-modal models (LMMs) demonstrate promising capabilities in segmentation and comprehension, they still struggle with two limitations: inaccurate segmentation and hallucinated comprehension. These challenges stem primarily from constraints in weak visual comprehension and a lack of fi…

Monkey: Image Resolution and Text Label Are Important Things for Large Multi-modal Models

CVPR 2024highlight

Large Multimodal Models (LMMs) have shown promise in vision-language tasks but struggle with high-resolution input and detailed scene understanding. Addressing these challenges we introduce Monkey to enhance LMM capabilities. Firstly Monkey processes input images by dividing them into uniform patche…

Minimal Solutions for Relative Pose With a Single Affine Correspondence

CVPR 2020poster

In this paper we present four cases of minimal solutions for two-view relative pose estimation by exploiting the affine transformation between feature points and we demonstrate efficient solvers for these cases. It is shown, that under the planar motion assumption or with knowledge of a vertical dir…
