TSGB: Target-Selective Gradient Backprop for Probing CNN Visual Saliency

1 code implementation11 Oct 2021 Lin Cheng, Pengfei Fang, Yanjie Liang, Liao Zhang, Chunhua Shen, Hanzi Wang

Inspired by those observations, we propose a novel visual saliency method, termed Target-Selective Gradient Backprop (TSGB), which leverages rectification operations to effectively emphasize target classes and further efficiently propagate the saliency to the image space, thereby generating target-selective and fine-grained saliency maps.

Robust Visual Tracking via Statistical Positive Sample Generation and Gradient Aware Learning

no code implementations9 Nov 2020 Lijian Lin, Haosheng Chen, Yanjie Liang, Yan Yan, Hanzi Wang

In this paper, we propose a robust tracking method via Statistical Positive sample generation and Gradient Aware learning (SPGA) to address the above two limitations.

Correlation filter tracking with adaptive proposal selection for accurate scale estimation

no code implementations14 Jul 2020 Luo Xiong, Yanjie Liang, Yan Yan, Hanzi Wang

In this paper, we propose an adaptive proposal selection algorithm which can generate a small number of high-quality proposals to handle the problem of scale variations for visual object tracking.

Asynchronous Tracking-by-Detection on Adaptive Time Surfaces for Event-based Object Tracking

no code implementations13 Feb 2020 Haosheng Chen, Qiangqiang Wu, Yanjie Liang, Xinbo Gao, Hanzi Wang

To achieve this goal, we present an Adaptive Time-Surface with Linear Time Decay (ATSLTD) event-to-frame conversion algorithm, which asynchronously and effectively warps the spatio-temporal information of asynchronous retinal events to a sequence of ATSLTD frames with clear object contours.
