Inferring causal relations from observational long-term carbon and water fluxes records

open access: yesScientific Reports, 2022
Land, atmosphere and climate interact constantly and at different spatial and temporal scales. In this paper we rely on causal discovery methods to infer spatial patterns of causal relations between several key variables of the carbon and water cycles ...

Video Object Detection Guided by Object Blur Evaluation

open access: yesIEEE Access, 2020
In recent years, the excellent image-based object detection algorithms are transferred to the video object detection directly. These frame-by-frame processing methods are suboptimal owing to the degenerate object appearance such as motion blur, defocus ...

Hypercomplex Image- to- Image Translation

open access: yes2022 International Joint Conference on Neural Networks (IJCNN), 2022
Image-to-image translation (I2I) aims at transferring the content representation from an input domain to an output one, bouncing along different target domains. Recent I2I generative models, which gain outstanding results in this task, comprise a set of diverse deep networks each with tens of million parameters.
