Video processing system including advanced scene break detection methods for fades, dissolves and flashes

A method for detecting a scene transition in digitized video data comprising:

• determining if a hypothesized gradual transition is detected in the video data that ends with a current frame based at least on the current frame and one or more previous frames in the digitized video data, the hypothesized gradual transition having a length, a starting frame and an ending frame;
• generating a synthetically produced gradual transition spanning the length of the hypothesized gradual transition and based on input including the starting frame and ending frame of the hypothesized gradual transition;
• comparing the hypothesized gradual transition to the synthetically produced gradual transition;
• and
• marking the hypothesized gradual transition as a gradual transition only if the hypothesized gradual transition is sufficiently similar to the synthetically produced gradual transition.

A computer program product, tangibly stored on a computer-readable medium for detecting a scene transition in digitized video data, comprising instructions operable to cause a programmable processor to:

• determine if a hypothesized dissolve is detected in the video data that ends with a current frame based at least on the current frame and one or more previous frames in the digitized video data, the hypothesized dissolve having a length, a starting frame and an ending frame;
• generate a synthetic dissolve spanning the length of the hypothesized dissolve and based on input including the starting and ending frames of the hypothesized dissolve;
• compare the hypothesized dissolve to the synthetic dissolve;
• and
• mark the hypothesized dissolve as a dissolve only if the hypothesized dissolve is sufficiently similar to the synthetic dissolve.

A method for detecting a scene transition in digitized video data, comprising:

• detecting that a hypothesized dissolve is present;
• identifying where the hypothesized dissolve starts and ends, including identifying starting and ending frames and a length of the hypothesized dissolve;
• generating a synthetic dissolve using the starting frame, ending frame and length of the hypothesized dissolve;
• comparing one or more frames included in the hypothesized dissolve to frames included in the synthetic dissolve;
• and
• marking the hypothesized dissolve as a dissolve only if the hypothesized dissolve is sufficiently similar to the synthetic dissolve.
