Learning to utilize image second-order derivative information for crisp edge detection

no code implementations9 Jun 2024 Changsong Liu, Wei zhang, Yanyan Liu, Yimeng Fan, Mingyang Li, Wenlin Li

In the end, we propose a U-shape network named LUS-Net which is based on the SDMCM and BRM for crisp edge detection.

SFOD: Spiking Fusion Object Detector

1 code implementation CVPR 2024 Yimeng Fan, Wei zhang, Changsong Liu, Mingyang Li, Wenrui Lu

Thereby, we establish state-of-the-art classification results based on SNNs, achieving 93. 7\% accuracy on the NCAR dataset.

Learning with Rethinking: Recurrently Improving Convolutional Neural Networks through Feedback

no code implementations15 Aug 2017 Xin Li, Zequn Jie, Jiashi Feng, Changsong Liu, Shuicheng Yan

However, most of the existing CNN models only learn features through a feedforward structure and no feedback information from top to bottom layers is exploited to enable the networks to refine themselves.

FoveaNet: Perspective-aware Urban Scene Parsing

no code implementations ICCV 2017 Xin Li, Zequn Jie, Wei Wang, Changsong Liu, Jimei Yang, Xiaohui Shen, Zhe Lin, Qiang Chen, Shuicheng Yan, Jiashi Feng

Thus, they suffer from heterogeneous object scales caused by perspective projection of cameras on actual scenes and inevitably encounter parsing failures on distant objects as well as other boundary and recognition errors.

Prune the Convolutional Neural Networks with Sparse Shrink

no code implementations8 Aug 2017 Xin Li, Changsong Liu

These results have demonstrated the effectiveness of our "Sparse Shrink" algorithm.

Heteroscedastic Max-Min Distance Analysis

no code implementations CVPR 2015 Bing Su, Xiaoqing Ding, Changsong Liu, Ying Wu

Many discriminant analysis methods such as LDA and HLDA actually maximize the average pairwise distances between classes, which often causes the class separation problem.
