In ICG semantic drone dataset ,

• "train_frames" could be taken from - semantic_drone_dataset_semantics_v1.1\semantic_drone_dataset\training_set\images

• "train_masks" could be taken from - semantic_drone_dataset_semantics_v1.1\semantic_drone_dataset\training_set\gt\semantic\label_images

Please randomly seperate train and val set as you like make sure there are 360 for training and 40 for testing

Train frames

all other images except in val set

Train masks

all other images except in val set
