SIGNO-PERU-FER: A Multimodal RGB-D Dataset of Visuo-Gestural Facial Expressions in Peruvian Sign Language

SIGNO-PERU-FER is a multimodal RGB-D dataset of dynamic Visuo-Gestural Facial Expressions (VGFEs) in Peruvian Sign Language (LSP), designed to support research on non-manual sign language recognition, multimodal facial behavior modeling, and inclusive AI systems. It comprises 1,256 synchronized RGB-D video sequences from 16 native LSP signers across 14 VGFE categories selected for their visual similarity and classification challenges. Each sequence includes RGB video (1920×1080, 30 fps), depth maps (512×512), and 468 3D facial landmark points captured with an Azure Kinect DK under controlled laboratory conditions.#Category#Category1Annoyed8No2Bored9Sad3Crying10Smells bad4Disgust11Surprise5Happy12Thief6I don't know13Tired7Let's see14YesThe SIGNO-PERU-FER dataset is archived in Zenodo under restricted access due to the re-identification risk inherent to audiovisual recordings.
