Overview

ViAiSteady

Real-time video stabilization library

ViAiSteady is a high-performance, real-time video stabilization library written in C++ and optimized for a wide range of hardware platforms. It is designed to reduce camera shake and unwanted jitter in videos captured by smartphones, handheld cameras, airborne imaging systems, and other devices operating under challenging motion conditions.

The library supports both real-time stabilization during video capture and offline post-processing, delivering smoother and more stable video output.

By leveraging hardware-accelerated encoding to extract motion vectors, ViAiSteady reduces the computational overhead associated with traditional motion estimation techniques, making it particularly suitable for embedded systems and resource-constrained devices.

1How ViAiSteady works

Camera motion is taken from the video encoder, smoothed, then compensated in every frame.

  1. 01
    Input video

    Frames from the camera during capture, or a recorded video file.

  2. 02
    Motion vectors

    The hardware-accelerated encoder provides the motion vectors of each frame - no separate motion estimation.

  3. 03
    Camera path smoothing

    The global camera motion is estimated from the vectors; shake and jitter are separated from the intended motion.

  4. 04
    Stabilized output

    Each frame is compensated for the unwanted motion, giving smoother and more stable video.
