METHOD AND SYSTEM TO DETECT AND UTILIZE ATTRIBUTES OF FRAMES IN VIDEO SEQUENCES

摘要

The present disclosure relates to a method and a system for determining one or more attributes of each frame of a plurality of frames of a video. The method includes evaluating a first set of pre-defined values for the each frame of the plurality of frames, determining a second set of pre-defined values for the each frame of the plurality of frames based on a second pre-determined criterion, computing a third pre-defined value for the each frame based on a third pre-determined criterion, and identifying the one or more attributes of the each frame. The identified one or more attributes is utilized for stabilizing a rate control model of an encoder. The evaluating is based on a first pre-determined criterion.

1. A method for determining one or more attributes of each frame of a plurality of frames of a video, the method comprising:
evaluating a first set of pre-defined values for said each frame of said plurality of frames, wherein said evaluating being based on a first pre-determined criterion, said first pre-determined criterion comprises:
categorizing one or more pixel values of each macroblock of said each frame based on one or more components of said each frame; andcalculating said first set of pre-defined values from each of said one or more components of said each frame based on a pre-defined criterion. determining a second set of pre-defined values for said each frame of said plurality of frames based on a second pre-determined criterion, said second pre-determined criterion comprises calculation of said second set of pre-defined values for said each frame for a component of said one or more components; computing a third pre-defined value for said each frame based on a third pre-determined criterion, said third pre-determined criterion comprises subtracting said first set of pre-defined values of a previous frame from said first set of pre-defined values of a present frame, and said second set of pre-defined values of a previous frame from said second set of pre-defined values of a present frame; and identifying said one or more attributes of said each frame, said identified one or more attributes being utilized for stabilizing a rate control model of an encoder.
