Revisiting the Encoding of Satellite Image Time Series

1 code implementation3 May 2023 Xin Cai, Yaxin Bi, Peter Nicholl, Roy Sterritt

Satellite Image Time Series (SITS) representation learning is complex due to high spatiotemporal resolutions, irregular acquisition times, and intricate spatiotemporal interactions.

Source-Free Adaptive Gaze Estimation by Uncertainty Reduction

1 code implementation CVPR 2023 Xin Cai, Jiabei Zeng, Shiguang Shan, Xilin Chen

In light of this, we present an unsupervised source-free domain adaptation approach for gaze estimation, which adapts a source-trained gaze estimator to unlabeled target domains without source data.

Tampered VAE for Improved Satellite Image Time Series Classification

no code implementations30 Mar 2022 Xin Cai, Yaxin Bi, Peter Nicholl

We hope the proposed framework can serve as a baseline for crop classification with SITS for its modularity and simplicity.

FlatteNet: A Simple Versatile Framework for Dense Pixelwise Prediction

1 code implementation22 Sep 2019 Xin Cai, Yi-Fei PU

In this paper, we focus on devising a versatile framework for dense pixelwise prediction whose goal is to assign a discrete or continuous label to each pixel for an image.

An overlapping-free leaf segmentation method for plant point clouds

no code implementations12 Aug 2019 Dawei Li, Yan Cao, Guoliang Shi, Xin Cai, Yang Chen, Sifan Wang, Siyuan Yan

The proposed method can also facilitate the automatic traits estimation of each single leaf (such as the leaf area, length, and width), which has potential to become a highly effective tool for plant research and agricultural engineering.

An Integrated Image Filter for Enhancing Change Detection Results

no code implementations2 Jul 2019 Dawei Li, Siyuan Yan, Xin Cai, Yan Cao, Sifan Wang

In this paper, we present an integrated filter which comprises a weighted local guided image filter and a weighted spatiotemporal tree filter.

Bayesian inverse regression for dimension reduction with small datasets

no code implementations19 Jun 2019 Xin Cai, Guang Lin, Jinglai Li

We consider supervised dimension reduction problems, namely to identify a low dimensional projection of the predictors $\-x$ which can retain the statistical relationship between $\-x$ and the response variable $y$.
