Abstract
A method of processing images to determine at least one signature of a film. The method includes a step of selecting chronologically a series of images from said film, a step of evaluating shifts relating to at least one descriptor corresponding to a physical property between consecutive images in order to obtain primary visual shifts, a step of calculating differences between said primary visual shifts to determine secondary visual shifts, a step of calculating differences between said secondary visual shifts to determine tertiary visual shifts, and a step of determining a mean value and a standard deviation of the primary, secondary, and tertiary visual shifts to obtain the signature of the film.
Claims11
A method of processing images to determine at least one signature of a film, comprising the steps of:
- selecting chronologically a series of images from the film;
- obtaining primary visual shifts as shifts of at least one descriptor of a physical property between consecutive images of the series;
- calculating secondary visual shifts as differences between said primary visual shifts;
- calculating tertiary visual shifts as differences between said secondary visual shifts;
- and
- determining a signature of the film as a mean value and a standard deviation of the primary, secondary, and tertiary visual shifts.
An image processing device for determining at least one signature of a film, comprising:
- selection means, for selecting chronologically a series of images from said film;
- obtaining means for obtaining primary visual shifts as shifts of at least one descriptor of a physical property between consecutive images of the series;
- calculation means for calculating secondary visual shifts as differences between said primary visual shifts;
- calculation means for calculating tertiary visual shifts as differences between said secondary visual shifts;
- and
- determination means for determining a signature of the film as a mean value and a standard deviation of the primary, secondary, and tertiary visual shifts.
An image processing device for determining at least one signature of a film, the device being configured to:
- select chronologically a series of images from said film;
- obtain primary visual shifts as shifts of at least one descriptor of a physical property between consecutive images;
- calculate secondary visual shifts as differences between said primary visual shifts;
- calculate tertiary visual shifts as differences between said secondary visual shifts;
- and
- determine a signature of the film as a mean value and a standard deviation of the primary, secondary, and tertiary visual shifts.
