What-Where Transformer: A Slot-Centric Visual Backbone for Concurrent Representation and Localization

Ryota Yoshihashi, Masahiro Kada, Satoshi Ikehata +2

Many image understanding tasks involve identifying what is present and where it appears. However, tasks that address where, such as object discovery, detection, and segmentation, a…

Finding a Needle in a Haystack: Tiny Flying Object Detection in 4K Videos using a Joint Detection-and-Tracking Approach

Ryota Yoshihashi, Rei Kawakami, Shaodi You +3

Detecting tiny objects in a high-resolution video is challenging because the visual information is little and unreliable. Specifically, the challenge includes very low resolution o…

Hybrid Loss for Learning Single-Image-based HDR Reconstruction

Kenta Moriwaki, Ryota Yoshihashi, Rei Kawakami +2

This paper tackles high-dynamic-range (HDR) image reconstruction given only a single low-dynamic-range (LDR) image as input. While the existing methods focus on minimizing the mean…

Classification-Reconstruction Learning for Open-Set Recognition

Ryota Yoshihashi, Wen Shao, Rei Kawakami +3

Open-set classification is a problem of handling `unknown' classes that are not contained in the training dataset, whereas traditional classifiers assume that only known classes ap…
