Polynomial Regression Network for Variable-Number Lane Detection

no code implementations ECCV 2020 Bingke Wang, Zilei Wang, Yixin Zhang

Most of previous methods utilize semantic segmentation to identify the regions of traffic lanes in an image, and then adopt some curve-fitting method to reconstruct the lanes.

Low-confidence Samples Matter for Domain Adaptation

1 code implementation6 Feb 2022 Yixin Zhang, Junjie Li, Zilei Wang

Representing the target data structure in such a way would overlook the huge low-confidence samples, resulting in sub-optimal transferability that is biased towards the samples similar to the source domain.

DualNet: Learn Complementary Features for Image Recognition

1 code implementation ICCV 2017 Saihui Hou, Xu Liu, Zilei Wang

Here two parallel neural networks are coordinated to learn complementary features and thus a wider network is constructed.

VegFru: A Domain-Specific Dataset for Fine-Grained Visual Categorization

2 code implementations ICCV 2017 Saihui Hou, Yushan Feng, Zilei Wang

While the existing datasets for FGVC are mainly focused on animal breeds or man-made objects with limited labelled data, VegFru is a larger dataset consisting of vegetables and fruits which are closely associated with the daily life of everyone.
