Description

This feature is suitable for first-timers. But can be picked by any contributor.

Currently imglab supports exporting labelled data in Pascal VOC, COCO format. We want to let users export data in YOLO format as well.

target folder : data formaters

Please check how export feature is implemented for other formats in data formaters

Research direction
The issue is about adding YOLO format export to imglab. Start by examining the existing export implementations in the 'data formaters' folder (https://github.com/NaturalIntelligence/imglab/blob/master/dataformaters). Understand how Pascal VOC and COCO exports are structured, then implement a similar module for YOLO. The YOLO format uses normalized coordinates. Check issue comments for any additional guidance.
