问题:没有基于spiking camera的光流方法,可行的策略:一是转成rgb帧,计算光流,但是会浪费时间;二是简单方法存在运动模糊,复杂的方法又太复杂,所以,需要一种定制的方法。另一个挑战是没有基于spiking camera的光流数据集,建立真实数据集很困难,合成数据集是更好的选择。 主要内容:本文提出了SCFlow,一种可以直
Optical Flow Estimation for Spiking Camera As a bio-inspired sensor with high temporal resolution, the spiking camera has an enormous potential in real applications, especially for motion estimation in high-speed scenes. However, frame-based and event-based methods are not well suited to spike ...
Second, we describe the optical flow estimation from spiking cameras. 2.1 Optical flow estimation from RGB camera The fundamental theory of optical flow based on RGB cameras was first proposed by Gibson [24] until Horn and Schunck [25] proposed the first seminal variational framework that ensures...

Then, the feature descriptor is formed based on the joint entropy of difference in flow magnitude and orientation collected from the regular grid of each frame in the action sequence. Finally, in order to incorporate long-term temporal dependency, a spiking neural network is embedded to aggregate...
We monitored the behavior of the fly in the chamber using a monochrome board camera operating at 30 fps and equipped with an IR-transmitting lens (DMM 22BUC03-ML, Imaging Source). A custom-built olfactometer delivered a constant flow of air (100 mL/min) and switched between clean ...
our results demonstrate that ORCHID allows high-throughput, dynamic estimation of DFGABAAin a cell-type-specific manner. This will assist in the study of inhibitory synaptic transmission and Cl−homoeostasis in the nervous system and establish a precedent for using all-optical methods to assess io...
