: Calculate the first and second derivatives of the landmark coordinates to capture the speed and fluidity of the signs.

The file appears to be a specific clip from the ASL 1000 Dataset , a high-fidelity collection of American Sign Language (ASL) videos designed for research in gesture analysis and sign recognition. latasha1_02mp4

Once extracted, these features are usually saved in structured formats such as: : Calculate the first and second derivatives of

: 21 points per hand to capture finger articulation and "handshape". : Tracking the shoulders, elbows, and wrists to

: Tracking the shoulders, elbows, and wrists to define the "signing space." 2. Temporal Normalization

: If "latasha1_02.mp4" has missing frames or variable frame rates, use linear interpolation to fill gaps in the landmark coordinates. 3. Feature Encoding

To turn raw landmarks into a feature vector for a model (like a Transformer or LSTM), apply the following:
