Video comparison using color histograms

摘要

Methods, apparatus and articles of manufacture for video comparison using color histograms are disclosed. Example methods disclosed herein to compare video sequences include determining a color histogram corresponding to an input video sequence based on color values of pixels sampled from a plurality of video frames of the input video sequence. Such disclosed example methods also include adjusting the color histogram corresponding to the input video sequence based on a first reference color histogram corresponding to a first reference video sequence different from the input video sequence to determine an adjusted color histogram corresponding to the input video sequence. Such disclosed example methods further include comparing the adjusted color histogram and the first reference color histogram to determine whether the first reference video sequence matches the input video sequence.

1. A method to compare video sequences, the method comprising:
determining, by executing an instruction with a processor, a color histogram corresponding to an input video sequence based on color values of pixels sampled from a plurality of video frames of the input video sequence; adjusting, by executing an instruction with the processor, the color histogram corresponding to the input video sequence based on a first reference color histogram corresponding to a first reference video sequence different from the input video sequence to determine an adjusted color histogram corresponding to the input video sequence; and comparing, by executing an instruction with the processor, the adjusted color histogram and the first reference color histogram to determine whether the first reference video sequence matches the input video sequence.
