Research of data representation for event data to improve object detection performance presented at SSII 2023

Research of data representation for event data to improve object detection performance presented at SSII 2023
We had a booth to show our research about event camera data processing for object detection at Symposium on Sensing via Image Information (SSII) 2023, Japan.

The title of this work is "Data representation of event data for object detection". Although event camera can contribute a lot for reducing energy consumption, there are several difficulties in object detection due to its asynchrony, sparsity and much less pixel intensity than conventional imager. In order to overcome these difficulties, we tested several data representation that are specific to event data, concretely, number of accumulated event in each pixel and time stamp information. Thanks to the data representation, we could achieve better object detection performance than SOTA (improved 7 pt in F1 score).
