LST-Net: Learning a Convolutional Neural Network with a Learnable Sparse Transform

no code implementations ECCV 2020 Lida Li, Kun Wang, Shuai Li, Xiangchu Feng, Lei Zhang

The 2D convolutional (Conv2d) layer is the fundamental element to a deep convolutional neural network (CNN).

SimAM: A Simple, Parameter-Free Attention Module for Convolutional Neural Networks

2 code implementations Proceedings of Machine Learning Research 2022 Lingxiao Yang, Ru-Yuan Zhang, Lida Li, Xiaohua Xie

Another advantage of the module is that most of the operators are selected based on the solution to the defined energy function, avoiding too many efforts for structure tuning.

Towards Robust 2D Convolution for Reliable Visual Recognition

no code implementations18 Mar 2022 Lida Li, Shuai Li, Kun Wang, Xiangchu Feng, Lei Zhang

2D convolution (Conv2d), which is responsible for extracting features from the input image, is one of the key modules of a convolutional neural network (CNN).

Spatial Feature Calibration and Temporal Fusion for Effective One-stage Video Instance Segmentation

1 code implementation CVPR 2021 Minghan Li, Shuai Li, Lida Li, Lei Zhang

To further explore temporal correlation among video frames, we aggregate a temporal fusion module to infer instance masks from each frame to its adjacent frames, which helps our framework to handle challenging videos such as motion blur, partial occlusion and unusual object-to-camera poses.

Learning Image-adaptive 3D Lookup Tables for High Performance Photo Enhancement in Real-time

1 code implementation30 Sep 2020 Hui Zeng, Jianrui Cai, Lida Li, Zisheng Cao, Lei Zhang

The small CNN works on the down-sampled version of the input image to predict content-dependent weights to fuse the multiple basis 3D LUTs into an image-adaptive one, which is employed to transform the color and tone of source images efficiently.

Grid Anchor based Image Cropping: A New Benchmark and An Efficient Model

1 code implementation18 Sep 2019 Hui Zeng, Lida Li, Zisheng Cao, Lei Zhang

The employed evaluation metrics such as intersection-over-union cannot reliably reflect the real performance of a cropping model, either.

Reliable and Efficient Image Cropping: A Grid Anchor based Approach

1 code implementation CVPR 2019 Hui Zeng, Lida Li, Zisheng Cao, Lei Zhang

Consequently, a grid anchor based cropping benchmark is constructed, where all crops of each image are annotated and more reliable evaluation metrics are defined.
