Simulating events from a video **will not work for any video**. The input video needs to have a sufficiently high framerate: the pixel displacement between successive images needs to be small (i.e. a few pixels at most). Otherwise, the simulated events will be of poor quality. +### Preliminaries (basic knowledge of ROS) + +To follow this tutorial, it will be helpful to have some basic understanding of ROS (i.e. know what ROS nodes, messages and topics are). If you do know ROS yet, we recommend to skim through the [ROS beginner tutorials](http://wiki.ros.org/ROS/Tutorials), in particular [Understanding ROS Nodes](http://wiki.ros.org/ROS/Tutorials/UnderstandingNodes) and [Understanding ROS topics](http://wiki.ros.org/ROS/Tutorials/UnderstandingTopics). + ### Overview An overview of the conversion method is shown in the diagram below. First, we will extract the individual frames from the input video in a folder. Second, we will run ESIM, providing the image folder as an input to simulate events.
