Pseudocode Yes Algorithm 1 Color Completion Algorithm
Open Source Code Yes Project page: https://wukailu.github.io/Unique3D/.
Open Datasets Yes Utilizing a subset of the Objaverse dataset as delineated by LGM [53], we apply a rigorous filtration process to exclude scenes containing multiple objects, low-resolution imagery, and unidirectional faces, leading to a refined dataset of approximately 50k objects.
Dataset Splits No The paper uses the Objaverse dataset for training and Google Scanned Objects (GSO) for evaluation, but does not specify train/validation/test splits (e.g., percentages or counts) for its own model training.
Hardware Specification Yes The entire training takes around 4 days on 8 NVIDIA RTX4090 GPUs.
Software Dependencies No The initial level of image generation is initialized with the weight of the Stable Diffusion Image Variations Model [40], while the subsequent level employs an upscaled version fine-tuned from Control Net-Tile [70]. The final stage uses the pre-trained Real-ESRGAN model [58].
Experiment Setup Yes The reconstruction process involves 300 iterations using the SGD optimizer [3], with a learning rate of 0.3. The weight of expansion regularization is set to 0.1. Subsequent refinement takes 100 iterations, maintaining the same optimization parameters.
