SEnSeI: A Deep Learning Module for Creating Sensor Independent Cloud Masks

no code implementations16 Nov 2021 Alistair Francis, John Mrziglod, Panagiotis Sidiropoulos, Jan-Peter Muller

We introduce a novel neural network architecture -- Spectral ENcoder for SEnsor Independence (SEnSeI) -- by which several multispectral instruments, each with different combinations of spectral bands, can be used to train a generalised deep learning model.

Measuring spatial uniformity with the hypersphere chord length distribution

no code implementations12 Apr 2020 Panagiotis Sidiropoulos

Data uniformity is a concept associated with several semantic data characteristics such as lack of features, correlation and sample bias.

Real-time tracker with fast recovery from target loss

no code implementations12 Feb 2019 Alessandro Bay, Panagiotis Sidiropoulos, Eduard Vazquez, Michele Sasdelli

When the confidence is low, we avoid updating the object's position through the feature map; instead, the tracker passes to a single-frame failure mode, during which the patch's low-level visual content is used to swiftly update the object's position, before recovering from the target loss in the next frame.

Hide and Seek tracker: Real-time recovery from target loss

no code implementations20 Jun 2018 Alessandro Bay, Panagiotis Sidiropoulos, Eduard Vazquez, Michele Sasdelli

In the case of a low confidence, the position update is rejected and the tracker passes to a single-frame failure mode, during which the patch low-level visual content is used to swiftly update the object position, before recovering from the target loss in the next frame.

N-sphere chord length distribution

no code implementations20 Nov 2014 Panagiotis Sidiropoulos

This work studies the chord length distribution, in the case where both ends lie on a $N$-dimensional hypersphere ($N \geq 2$).
