Abstract
A method for detecting scene cuts and similar pictures in a video sequence, including receiving pictures in a video sequence, extracting a set of features from two temporally consecutive pictures, computing a sum of square errors for the set of features with respect to the features of the previous picture, determining whether the error exceeds a predefined threshold and in response to the error exceeding the predefined threshold, detecting a scene change, and determining whether the error is less than a certain threshold thus detecting a similar picture has been found.
Claims20
A method for detecting scene cuts in a video sequence, comprising:
- receiving images in a video sequence;
- extracting a set of features from two temporally consecutive images;
- computing a sum of square errors for the set of features with respect to the features of the previous image;
- determining whether the sum of square errors exceeds a predefined threshold;
- and
- in response to the sum of square errors exceeding the predefined threshold, detecting a scene change.
A method for detecting similar images in a video sequence, comprising:
- receiving images in a video sequence;
- determining a plurality of features from two temporally consecutive images;
- determining an error for the plurality of features with respect to the features of the previous image;
- determining whether the error exceeds a predefined threshold;
- and
- in response to the error exceeding the predefined threshold, determining whether the images are similar.
An apparatus, comprising
- a controller for detecting similar images in a video sequence, including receiving images in a video sequence, determining a plurality of features from two temporally consecutive images, determining an error for the plurality of features with respect to the features of the previous image, determining whether the error exceeds a predefined threshold, and in response to the error exceeding the predefined threshold, determining whether the images are similar.
A system, comprising
- a detector to receive images in a video sequence, determine a plurality of features from two temporally consecutive images, determine an error for the plurality of features with respect to the features of the previous image, determine whether the error exceeds a predefined threshold, in response to the error exceeding the predefined threshold determine whether the images are similar and generate a signal indicating scene change;
- and
- a processing device for receiving the signal indicating a scene change.
A machine-accessible medium including instructions that, when executed, cause a machine to:
- receive images in a video sequence;
- determine a plurality of features from two temporally consecutive images;
- determine an error for the plurality of features with respect to the features of the previous image;
- determine whether the error exceeds a predefined threshold;
- and
- in response to the error exceeding the predefined threshold, determine whether the images are similar.
