Abstract
A method of correcting dynamic vision sensor (DVS) events is described. The method generates event data including events representing motion information of an object included in an image. Additionally, the method generates image data capturing an image and generates edge data representing edge information of the image based on the image data. The method also generates omitted events of the event data based on the edge data. Accuracy of the event data and performance of machine vision devices and systems operating based on the event data are enhanced by supplementing the omitted events of the event data provided from the DVS, using the edge information.
