Abstract
A method implemented in an electronic device. The method includes: obtaining two temporally spaced apart images capturing the same scene of a video stream; obtaining a motion map representing differences between the components of the images in at least one video channel; and obtaining at least one geometric shape encompassing a set of moving portions of the motion map. Also provided are the corresponding electronic device, the computer program product and the medium.
Claims20
A motion detection method, implemented in an electronic device, said method comprising:
- obtaining at least two temporally spaced apart images capturing a same scene of a video stream;
- obtaining at least a first motion map divided into portions representing differences between values of at least two video channels for a zone of at least two of said images;
- and
- obtaining at least one geometric shape encompassing a set of moving portions of said first motion map.
An electronic device comprising:
- at least one processor, said at least one processor being configured to:
- obtain at least two temporally spaced apart images capturing a same scene of a video stream;
- obtaining at least a first motion map divided into portions representing differences between values of at least two video channels, for a zone of at least two of said images;
- and
- obtaining at least one geometric shape encompassing a set of moving portions of said first motion map.
A non-transitory computer readable medium comprising a computer program recorded therein comprising instructions for implementing, when the program is executed by a processor of an electronic device, a motion detection method implemented in the electronic device, said method comprising:
- obtaining at least two temporally spaced apart images capturing a same scene of a video stream;
- obtaining at least one first motion map divided into portions representing differences between values of at least two video channels for a zone of at least two of said images;
- and
- obtaining at least one geometric shape encompassing a set of moving portions of said first motion map.
