Towards Explaining Satellite Based Poverty Predictions with Convolutional Neural Networks

no code implementations1 Dec 2023 Hamid Sarmadi, Thorsteinn Rögnvaldsson, Nils Roger Carlsson, Mattias Ohlsson, Ibrahim Wahab, Ola Hall

Deep convolutional neural networks (CNNs) have been shown to predict poverty and development indicators from satellite images with surprising accuracy.

3D Reconstruction and Alignment by Consumer RGB-D Sensors and Fiducial Planar Markers for Patient Positioning in Radiation Therapy

no code implementations22 Mar 2021 Hamid Sarmadi, Rafael Muñoz-Salinas, M. Álvaro Berbís, Antonio Luna, Rafael Medina-Carnicer

METHODS: The proposed method relies on a 3D reconstruction approach that fuses, in real-time, artificial and natural visual landmarks recorded from a hand-held RGB-D sensor.

Simultaneous Multi-View Camera Pose Estimation and Object Tracking with Square Planar Markers

1 code implementation16 Mar 2021 Hamid Sarmadi, Rafael Muñoz-Salinas, M. A. Berbís, R. Medina-Carnicer

From a video sequence showing a rigid set of planar markers recorded from multiple cameras, the proposed method is able to automatically obtain the three-dimensional configuration of the markers, the extrinsic parameters of the cameras, and the relative pose between the markers and the cameras at each frame.

Detection of Binary Square Fiducial Markers Using an Event Camera

no code implementations11 Dec 2020 Hamid Sarmadi, Rafael Muñoz-Salinas, Miguel A. Olivares-Mendez, Rafael Medina-Carnicer

We detect the edges of the markers by detecting line segments in an image created from events in the current packet.
