Core Algorithms in Digital Image Stabilization

Core algorithms in digital image stabilization are fundamental to reducing motion blur and jitters caused by camera shake or movement. These algorithms analyze consecutive frames to detect unwanted shifts and compensate for them effectively. Techniques such as motion estimation and frame alignment are central to this process.

Commonly used algorithms include optical flow, feature-based tracking, and phase correlation. Optical flow estimates pixel movements between frames by analyzing intensity changes, making it suitable for smooth motion compensation. Feature-based tracking identifies key points in the image and tracks their movement across frames to stabilize the video. Phase correlation determines the shift between images by examining their frequency domain representations, offering high accuracy in alignment.

Implementing these core algorithms involves several steps:
