Spike Camera and Its Coding Methods
This addresses the problem of capturing and reconstructing high-speed video for applications in motion analysis or surveillance, but appears incremental as it builds on existing spike-based sensing concepts.
The paper introduces a spike camera that captures luminance intensity variations and fires spikes when thresholds are exceeded, enabling reconstruction of high-speed movement images from spike stream patterns.
This paper introduces a spike camera with a distinct video capture scheme and proposes two methods of decoding the spike stream for texture reconstruction. The spike camera captures light and accumulates the converted luminance intensity at each pixel. A spike is fired when the accumulated intensity exceeds the dispatch threshold. The spike stream generated by the camera indicates the luminance variation. Analyzing the patterns of the spike stream makes it possible to reconstruct the picture of any moment which enables the playback of high speed movement.
