Unsupervised Optical Flow Estimation with Dynamic Timing Representation for Spike Camera
Lujie Xia, Ziluo Ding, Rui Zhao +5
Efficiently selecting an appropriate spike stream data length to extract precise information is the key to the spike vision tasks. To address this issue, we propose a dynamic timin…
A Robust Visual Sampling Model Inspired by Receptive Field
Liwen Hu, Lei Ma, Dawei Weng +1
Spike camera mimicking the retina fovea can report per-pixel luminance intensity accumulation by firing spikes. As a bio-inspired vision sensor with high temporal resolution, it ha…
Robust Ellipsoid-specific Fitting via Expectation Maximization
Zhao Mingyang, Jia Xiaohong, Ma Lei +3
Ellipsoid fitting is of general interest in machine vision, such as object detection and shape approximation. Most existing approaches rely on the least-squares fitting of quadrics…
Human Perception-based Evaluation Criterion for Ultra-high Resolution Cell Membrane Segmentation
Ruohua Shi, Wenyao Wang, Zhixuan Li +6
Computer vision technology is widely used in biological and medical data analysis and understanding. However, there are still two major bottlenecks in the field of cell membrane se…
