Preatmospheric Detection of a Meter-sized Earth Impactor
The Planetary Science Journal, 2023 On 2020 September 18 U.S. Government (USG) sensors detected a bolide with peak bolometric magnitude of −19 over the Western Pacific. The impact was also detected by the Geostationary Lightning Mapper instrument on the GOES-17 satellite and infrasound ...

Detecting out-of-context objects using contextual cues [PDF]
IJCAI-ECAI 2022, 2022 This paper presents an approach to detect out-of-context (OOC) objects in an image. Given an image with a set of objects, our goal is to determine if an object is inconsistent with the scene context and detect the OOC object with a bounding box. In this work, we consider commonly explored contextual relations such as co-occurrence relations, the ...

Debiased albedo distribution for Near Earth Objects
Icarus, 2020 We extend the most recent orbital and absolute magnitude Near Earth Object (NEO) model (Granvik et al., 2018) to provide a statistical description of NEO geometric albedos. Our model is calibrated on NEOWISE albedo data for the NEO population and reproduces these data very well once a simple model for the NEOWISE observational biases is applied.

PROB: Probabilistic Objectness for Open World Object Detection [PDF]
arXiv, 2022 Open World Object Detection (OWOD) is a new and challenging computer vision task that bridges the gap between classic object detection (OD) benchmarks and object detection in the real world. In addition to detecting and classifying seen/labeled objects, OWOD algorithms are expected to detect novel/unknown objects - which can be classified and ...

Construction of Latent Descriptor Space and Inference Model of Hand-Object Interactions [PDF]
IEICE Trans. on Info. and Sys., Vol.E100-D, No.6, pp.1350-1359,
2017, 2017 Appearance-based generic object recognition is a challenging problem because all possible appearances of objects cannot be registered, especially as new objects are produced every day. Function of objects, however, has a comparatively small number of prototypes.
