Researchers have introduced Sapiens2, a new family of high-resolution transformer models designed for human-centric vision tasks. These models, ranging from 0.4 to 5 billion parameters, support native 1K resolution and hierarchical variants up to 4K. Sapiens2 achieves improved performance through a unified pretraining objective combining masked image reconstruction with self-distilled contrastive learning, training on a dataset of 1 billion human images, and architectural enhancements like windowed attention for longer spatial context.
