Joint COCO and Mapillary Workshop at ICCV 2019: COCO Instance Segmentation Challenge Track

no code implementations • 6 Oct 2020 • Zeming Li, Yuchen Ma, Yukang Chen, Xiangyu Zhang, Jian Sun

In this report, we present our object detection/instance segmentation system, MegDetV2, which works in a two-pass fashion, first to detect instances then to obtain segmentation.

BorderDet: Border Feature for Dense Object Detection

2 code implementations • ECCV 2020 • Han Qiu, Yuchen Ma, Zeming Li, Songtao Liu, Jian Sun

In this paper, We propose a simple and efficient operator called Border-Align to extract "border features" from the extreme point of the border to enhance the point feature.

A Novel Artificial Fish Swarm Algorithm for Pattern Recognition with Convex Optimization

no code implementations • 1 Dec 2016 • Lei Shi, Rui Guo, Yuchen Ma

Among these parameters, visual and step are very significant in view of the fact that artificial fish basically move based on these parameters.
