Mitigate Target-level Insensitivity of Infrared Small Target Detection via Posterior Distribution Modeling

1 code implementation13 Mar 2024 Haoqing Li, Jinfu Yang, Yifei Xu, Runshi Wang

Infrared Small Target Detection (IRSTD) aims to segment small targets from infrared clutter background.

Click on Mask: A Labor-efficient Annotation Framework with Level Set for Infrared Small Target Detection

1 code implementation19 Oct 2023 Haoqing Li, Jinfu Yang, Yifei Xu, Runshi Wang

Due to the small size of infrared targets, manual annotation consumes more resources and restricts the development of this field.

ILNet: Low-level Matters for Salient Infrared Small Target Detection

1 code implementation24 Sep 2023 Haoqing Li, Jinfu Yang, Runshi Wang, Yifei Xu

Due to the dearth of high-level semantic information, small infrared target features are weakened in the deep layers of the CNN, which underachieves the CNN's representation ability.

Robust Interference Mitigation techniques for Direct Position Estimation

no code implementations9 Aug 2023 Haoqing Li, Shuo Tang, Peng Wu, Pau Closas

Global Navigation Satellite System (GNSS) is pervasive in navigation and positioning applications, where precise position and time referencing estimations are required.

Online Fusion of Multi-resolution Multispectral Images with Weakly Supervised Temporal Dynamics

1 code implementation6 Jan 2023 Haoqing Li, Bhavya Duvvuri, Ricardo Borsoi, Tales Imbiriba, Edward Beighley, Deniz Erdogmus, Pau Closas

To evaluate the proposed methodology we consider a water mapping task where real data acquired by the Landsat and MODIS instruments are fused generating high spatial-temporal resolution image estimates.

Neural Network-based OFDM Receiver for Resource Constrained IoT Devices

no code implementations12 May 2022 Nasim Soltani, Hai Cheng, Mauro Belgiovine, Yanyu Li, Haoqing Li, Bahar Azari, Salvatore D'Oro, Tales Imbiriba, Tommaso Melodia, Pau Closas, Yanzhi Wang, Deniz Erdogmus, Kaushik Chowdhury

Here, ML blocks replace the individual processing blocks of an OFDM receiver, and we specifically describe this swapping for the legacy channel estimation, symbol demapping, and decoding blocks with Neural Networks (NNs).

Quantization

Online multi-resolution fusion of space-borne multispectral images

no code implementations26 Apr 2022 Haoqing Li, Bhavia Duvviri, Ricardo Borsoi, Tales Imbiriba, Edward Beighley, Deniz Erdogmus, Pau Closas

Satellite imaging has a central role in monitoring, detecting and estimating the intensity of key natural phenomena.

Model-Based Deep Autoencoder Networks for Nonlinear Hyperspectral Unmixing

no code implementations17 Apr 2021 Haoqing Li, Ricardo Augusto Borsoi, Tales Imbiriba, Pau Closas, José Carlos Moreira Bermudez, Deniz Erdoğmuş

Autoencoder (AEC) networks have recently emerged as a promising approach to perform unsupervised hyperspectral unmixing (HU) by associating the latent representations with the abundances, the decoder with the mixing model and the encoder with its inverse.
