RCNet: Reverse Feature Pyramid and Cross-scale Shift Network for Object Detection

no code implementations23 Oct 2021 Zhuofan Zong, Qianggang Cao, Biao Leng

Moreover, semantics from non-adjacent levels are diluted in the feature pyramid since only features at adjacent pyramid levels are merged by the local fusion operation in a sequence manner.

Beyond Trade-off: Accelerate FCN-based Face Detector with Higher Accuracy

no code implementations CVPR 2018 Guanglu Song, Yu Liu, Ming Jiang, Yujie Wang, Junjie Yan, Biao Leng

Fully convolutional neural network (FCN) has been dominating the game of face detection task for a few years with its congenital capability of sliding-window-searching with shared kernels, which boiled down all the redundant calculation, and most recent state-of-the-art methods such as Faster-RCNN, SSD, YOLO and FPN use FCN as their backbone.

Weakly-supervised Learning of Mid-level Features for Pedestrian Attribute Recognition and Localization

no code implementations17 Nov 2016 Kai Yu, Biao Leng, Zhang Zhang, Dangwei Li, Kaiqi Huang

Based on GoogLeNet, firstly, a set of mid-level attribute features are discovered by novelly designed detection layers, where a max-pooling based weakly-supervised object detection technique is used to train these layers with only image-level labels without the need of bounding box annotations of pedestrian attributes.
