To turn raw landmarks into a feature vector for a model (like a Transformer or LSTM), apply the following:
: Normalize all points relative to a "root" point (e.g., the base of the neck or center of the face) to make the features invariant to where the person is standing in the frame. latasha1_02mp4
To "prepare features" for this video in a machine learning or computer vision context, you should focus on extracting . Below is a breakdown of the standard features typically extracted for this specific dataset: 1. Pose and Landmark Extraction To turn raw landmarks into a feature vector
: 21 points per hand to capture finger articulation and "handshape". Pose and Landmark Extraction : 21 points per
: If "latasha1_02.mp4" has missing frames or variable frame rates, use linear interpolation to fill gaps in the landmark coordinates. 3. Feature Encoding
: Detailed mesh points to capture "non-manual markers" (facial expressions essential for ASL grammar).
The ASL 1000 dataset is pre-annotated with 2D landmarks, but for custom feature preparation, you can use frameworks like MediaPipe or OpenPose to generate:
