Questions about .aedat file

[lyhsieh]

Hello, sorry for disturbance. I'm a student studying computer vision. I have some questions related to this repository (https://github.com/SensorsINI/DHP19). Thanks for your reading this letter and I'm desperately looking forward to your reply.

I'm using DHP19 dataset and repository on GitHub(https://github.com/SensorsINI/DHP19). I found that we use matlab to process the original aedat file in DVS_movies, and related h5 files are generated.

I wonder how does the original DVS movies data look like? That is, how can I visualize the aedat file into some video formats that we're familiar with, such as mp4 or avi? In other words, I wonder whether the original .aedat file is RGB video or just gray scale video or it even contains no video, just motion vectors?

Thanks for your reply!

Hi,

the aedat files do not contain videos but event streams. Examples of how to visualize the event stream include using jAER (https://github.com/SensorsINI/jaer) or loading the file, slice the events and plot them in a frame (as done in this repository)
