[LEADERG APP] Annotation

[Introduction]

 

This APP is an application with multiple image annotation tools. It mainly includes the common LabelImg, Labelme, the Annotation tool developed by LEADERG, and supports PASCAL VOC XML, YOLO, labelme, VIA JSON and other common label formats.

 

So what is image annotation? Image annotation is often used to mark objects in the image, marking the [location] and [name] of the object in the image. When we have these annotations, we can use them for the input data set of machine learning, and then the machine can use these images and annotations to obtain the objects it needs to learn.
