PR Title

YOLO Data Cleaning

Summary

Deletes the empty labels, labels with no image and images with no labels to improve model training and make the data clean and organised.

Description

During the handling of labeled images some labels gets missing. Feeding this data to the model will result in poor training and accuracy. Each image has a corresponding text file (containing the cordinates for the bounding box in the image) with same name as the image. This script deletes the label with missing images vice versa. It also deletes a label file with no content in it which is equivalent to missing label. User has the option to select what he wants to do.

The changes are as follows:

• created check_label.py script
• added a readme file
• added a test data folder
