Alignment of Similarity-Transformed Images Based on Fourier--Mellin Transform Using Auxiliary Function Method
Shinji Yamashita, Yuma Kinoshita, Hitoshi Kiya
This paper proposes an algorithm for estimating the similarity transformation, namely translation, scale, and rotation, between two images with subpixel accuracy. Image registratio…
Boundary-Continuous Cross-Camera RGB Mapping via Hue-Split Model Trees
Yuma Kinoshita, Hitoshi Kiya
We propose a hue-split model-tree method for boundary-continuous cross-camera RGB mapping. Cross-camera RGB mapping aims to produce consistent color representations across cameras…
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…
Pre-training Autoencoder for Acoustic Event Classification via Blinky
Xiaoyang Liu, Yuma Kinoshita
In the acoustic event classification (AEC) framework that employs Blinkies, audio signals are converted into LED light emissions and subsequently captured by a single video camera.…
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…
