Details
- Description
- "Ghosting" is a visual artifact within a set of frames that exposes background information through foreground objects.
The term ghosting is commonly used for the effect that high contrast vertical edges appear horizontally shifted as additional, lower contrast "ghost edges" overlaying the original picture content transparently.
Ghosting may also be present in digital media when frame rates are not properly converted.
Customer experience is negatively affected as on screen motion or visual elements are harder to see or obscured completely due to ghosting. In most situations it is the result of faulty frame rate conversion software or hardware. It rarely is creative intent. - Definition
- Used in Checks, the system shall verify if the video contains material with ghosting within content. Optionally it may report the relevant location(s).
