Overlay Detection

The process of automatically identifying graphical or textual elements overlaid on top of video content, such as pop-up graphics, watermarks, banners, subtitles, logos, and text annotations. Overlay detection uses computer vision techniques including edge detection, shape recognition, and optical character recognition to locate and classify overlays so they can be selectively removed or modified. Accurate overlay detection is essential for video customization systems that aim to reduce visual distractions while preserving important content.
