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

A device for detecting a presence of a logo in a current picture of a video comprising:

• a memory;
• at least one processor configured to:
• determine a current candidate logo shape in said current picture and a preceding candidate logo shape in a picture preceding said current picture;
• calculate a first score value based at least partially on whether a distance between a center of said current and said preceding candidate logo bounding shapes is below a first threshold or whether an overlap between said current and said preceding candidate logo bounding shapes is above a second threshold;
• calculate a second score value based at least partially on whether an overlap between the current candidate logo bounding shape and a saliency mask of the current picture is above a third threshold, wherein the saliency mask identifies regions around saliency peaks;
• and
• detect the presence of a logo in the current picture based at least partially on a comparison of the first score value and the second score value.

A non-transitory computer readable medium with instructions stored therein which, upon execution, instruct at least one processor to:

• determine a current candidate logo bounding shape in a current picture and a preceding candidate logo bounding shape in a picture preceding said current picture;
• calculate a first score value based at least partially on whether a distance between center of said current and said preceding candidate logo bounding shapes is below a first threshold or whether an overlap between said current and said preceding candidate logo bounding shapes is above a second threshold;
• calculate a second score value based at least partially on whether an overlap between the current candidate logo bounding shape and a saliency mask of the current picture is above a third threshold, wherein the saliency mask identifies regions around saliency peaks;
• and
• detect a presence of a loqo in the current picture based at least partially on a comparison of the first score value and the second score value.
