Sapiens của Meta AI: Nền tảng cho các Mô hình Thị giác Người

In this video we dive into Sapiens, a new family of models for four fundamental human-centric tasks, presented by Meta AI in a recent research paper titled "Sapiens: Foundation for Human Vision Models".

The model's architecture is based on Vision Transformer (ViT), which for the first time pushed to train on 1K resolution images, x5 in size than DINOv2's input images size!

We cover the model's training process, which includes a self-supervised learning pretraining step, based on the masked-autoencoder (MAE) approach, which we also explain here.
