Automatic annotation system based on SAM

AutoLabel

This project is developed using PyQt and is inspired by SAM, creating an automatic annotation system based on the concept of LabelImg.

Features

Similar functionalities to LabelImg (although very basic).

Annotate the rect box

Automated annotations with SAM

1. Right mouse on the object you're interested in.

2. Left mouse to exclude the objects you're not interested in.

Saving

You can choose from three formats: YOLO, Pascal VOC and COCO, the default is YOLO.
Notice:

• If you choose the COCO format, it must be consistent from the beginning, otherwise, you will only obtain annotations for a single image.

Visualization

You can place the annotations in the same directory as the images, and the labels file name must be same with image file name.
If it is in COCO format, put annotations.json in the directory.

Hotkeys

Hotkey	Description
