Spk2ImgNet: Learning To Reconstruct Dynamic Scene From Continuous Spike Stream

no code implementations CVPR 2021 Jing Zhao, Ruiqin Xiong, Hangfan Liu, Jian Zhang, Tiejun Huang

Different from the conventional digital cameras that compact the photoelectric information within the exposure interval into a single snapshot, the spike camera produces a continuous spike stream to record the dynamic light intensity variation process.

Image Denoising via Adaptive Soft-Thresholding Based on Non-Local Samples

no code implementations CVPR 2015 Hangfan Liu, Ruiqin Xiong, Jian Zhang, Wen Gao

To estimate the expectation and variance parameters for the transform bands of a particular patch, we exploit the non-local correlation of image and collect a set of similar patches as data samples to form the distribution.
