Gran Turismo 4 Multiplayer Data - Upsampler

This dataset contains video and action labels of 1v1 races in the PS2 game Gran Turismo 4 for upsampling purposes.

It was used to train the multiplayer world model Multiverse.

Note: this code is only used to train an upsampler model to increase the frame resolution and details from 35x53 to 350x530.

The dataset is comprised 1v1 races footage at 1 fps, split into .hdf5 files.

Each frame has a shpae of (350, 530, 6), representing 2 RGB frames stacked together along the channel axis. As can be seen in the following figure:

And the two player action is an array of size (66) in the following structure:

Player	Range	Control	Meaning
Player 1	0–10	Gas	0 = no gas, 10 = max gas
Player 1	11–21	Brake	11 = no brake, 21 = max brake
Player 1	22–32	Steering	22 = max left, 27 = straight, 32 = max right
Player 2	33–43	Gas	33 = no gas, 43 = max gas
Player 2	44–54	Brake	44 = no brake, 54 = max brake
Player 2	55–65	Steering	55 = max left, 60 = straight, 65 = max right
