Device and method for detecting the presence of a logo in a picture

摘要

A method for detecting the presence of a logo in a current picture of a video is disclosed. The method comprises:
- determining (10) a current candidate logo bounding box in the current picture and a preceding candidate logo bounding box in a picture preceding the current picture ;
- detecting (16) the presence of a logo in the current picture if at least one of the following conditions (12) is fulfilled:
- the distance between the centers of the current and the preceding candidate logo bounding boxes is below a first threshold or an overlap between the current and the preceding candidate logo bounding boxes is above a second threshold; or
- an overlap between the current candidate logo bounding box and a saliency mask of the current picture is above a third, wherein the saliency mask identifies regions around saliency peaks.
