Scale and Rotation Estimation of Similarity-Transformed Images via Cross-Correlation Maximization Based on Auxiliary Function Method

Shinji Yamashita, Yuma Kinoshita, Hitoshi Kiya

This paper introduces a highly efficient algorithm capable of jointly estimating scale and rotation between two images with sub-pixel precision. Image alignment serves as a critica…

Scene-Segmentation-Based Exposure Compensation for Tone Mapping of High Dynamic Range Scenes

Yuma Kinoshita, Hitoshi Kiya

We propose a novel scene-segmentation-based exposure compensation method for multi-exposure image fusion (MEF) based tone mapping. The aim of MEF-based tone mapping is to display h…

Fine-Tuning Text-To-Image Diffusion Models for Class-Wise Spurious Feature Generation

AprilPyone MaungMaung, Huy H. Nguyen, Hitoshi Kiya +1

We propose a method for generating spurious features by leveraging large-scale text-to-image diffusion models. Although the previous work detects spurious features in a large-scale…
