Compression Network with Transformer for Approximate Nearest Neighbor Search

no code implementations30 Jul 2021 Haokui Zhang, Wenze Hu, Buzhou Tang, Xiaoyu Wang

Specifically, we propose a new network structure called Compression Network with Transformer (CNT) to compress the feature into a low dimensional space, and an inhomogeneous neighborhood relationship preserving (INRP) loss that aims to maintain high search accuracy.

Pseudo-LiDAR Based Road Detection

no code implementations28 Jul 2021 Libo Sun, Haokui Zhang, Wei Yin

Specifically, we exploit pseudo-LiDAR using depth estimation, and propose a feature fusion network where RGB and learned depth information are fused for improved road detection.

3D-ANAS: 3D Asymmetric Neural Architecture Search for Fast Hyperspectral Image Classification

1 code implementation12 Jan 2021 Haokui Zhang, Chengrong Gong, Yunpeng Bai, Zongwen Bai, Ying Li

Correspondingly, different models need to be designed for different datasets, which further increases the workload of designing architectures; 2) the mainstream framework is a patch-to-pixel framework.

Memory-Efficient Hierarchical Neural Architecture Search for Image Restoration

no code implementations24 Dec 2020 Haokui Zhang, Ying Li, Chengrong Gong, Hao Chen, Zongwen Bai, Chunhua Shen

For outer search space, we propose cell sharing strategy to save memory, and considerably accelerate the search speed.

Hyperspectral Classification Based on Lightweight 3-D-CNN With Transfer Learning

no code implementations7 Dec 2020 Haokui Zhang, Ying Li, Yenan Jiang, Peng Wang, Qiang Shen, Chunhua Shen

In contrast to previous approaches, we do not impose restrictions over the source data sets, in which they do not have to be collected by the same sensors as the target data sets.

Hyperspectral Image Classification with Spatial Consistence Using Fully Convolutional Spatial Propagation Network

no code implementations4 Aug 2020 Yenan Jiang, Ying Li, Shanrong Zou, Haokui Zhang, Yunpeng Bai

However, the existing CNN-based models operate at the patch-level, in which pixel is separately classified into classes using a patch of images around it.

Gradient Information Guided Deraining with A Novel Network and Adversarial Training

no code implementations9 Oct 2019 Yinglong Wang, Haokui Zhang, Yu Liu, Qinfeng Shi, Bing Zeng

However, the existing methods usually do not have good generalization ability, which leads to the fact that almost all of existing methods have a satisfied performance on removing a specific type of rain streaks, but may have a relatively poor performance on other types of rain streaks.

RGB-D Based Action Recognition with Light-weight 3D Convolutional Networks

no code implementations24 Nov 2018 Haokui Zhang, Ying Li, Peng Wang, Yu Liu, Chunhua Shen

Different from RGB videos, depth data in RGB-D videos provide key complementary information for tristimulus visual data which potentially could achieve accuracy improvement for action recognition.
