Tagged images with LEGO bricks moving on the conveyor belt

Description

The data set conatins tagged images conatining LEGO bricks used for traning LEGO bricks detecting network. The dataset contains frames taken from video recordings of lego bricks moving on a conveyor belt. The images conatin from 0 to 7 bricks. In total there are 5459 tagged lego bricks in 4340 images and 3390 images without any bricks in them. The images are in FullHD resolution (1920x1080) and were taken from videos recorded with a Huawei p20 Pro camera (1920x1080 resolution, H.264 high profile codec, 15 frames per second).

The immages were tagged with coordinates of LEGO bricks bounding boxes. The label are stored in text files named as the image. The label were generated using labeImg software (https://github.com/tzutalin/labelImg) and are stored in YOLO format. The classes names are stored in classes.txt file inside the dataset. The content of the classes.txt file is as follows:
