3D reconstruction of typhoon Trami 2018 eye and eyewall clouds from airborne imaging

Meryl Algodon, Yukihiro Takahashi, Hisayuki Kubota, Mitsuteru Sato

Typhoons cause significant damage and casualties worldwide, making accurate intensity estimation essential for risk mitigation. However, analyzing typhoons-particularly their size, cloud formations, and development rate-is challenging due to their unpredictable nature and various environmental influences. Cloud morphology, particularly the cloud-top altitude difference …

Association between parental decisions regarding abortion and severity of fetal heart disease

Masahiro Nakao, Masanari Kuwabara, Mika Saito, Chinami Horiuchi et autres

The prenatal diagnosis of fetal heart disease potentially influences parental decision-making regarding pregnancy termination. Existing literature indicates that the severity, whether in complexity or lethality, significantly influences parental decisions concerning abortion. However, questions remain as to how fetal heart disease severity impacts …

Robust Perspective-n-Crater for Crater-based Camera Pose Estimation

Sofia McLeod, Chee Kheng Chng, Tatsuharu Ono, Yuta Shimizu et autres

Lunar survey missions require accurate estimation of satellite and/or sensor pose (position and attitude) to achieve precise surface measurement. Crater-based pose estimation (CBPE) holds promise to achieve the desired accuracy. However, current pose estimation methods suffer from one or more weaknesses, such …
