Abstract
Abstract A digital video processing method and an apparatus thereof are provided. The method for processing digital images received in the form of compressed video streams comprising the step of determining a region intensity histogram (RIH) based on information on motion compensation of inter frames. The RIH information is obtained based on the motion compensation values of inter frames, and the RIH information is a good indicator of motion information of a video scene. Also, since the RIH information is quite a good indicator of intensity of the video scene, video streams having similar intensities can be effectively searched by searching for similar video scenes based on the RIH information obtained by the digital video processing method.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
47 words
A method of processing video data comprising: determining motion intensity levels indicating a motion intensity of respective inter frames included in an input video data by using motion compensation information of the respective inter frames; and determining a histogram indicating frequency of the respective motion intensity levels.
Claim 2
Independent Claim
47 words
A method of processing video data comprising: determining motion intensity levels indicating a motion intensity of respective inter frames included in an input video data by using motion compensation information of the respective inter frames; and determining a histogram indicating frequency of the respective motion intensity levels.
Claim 3
Dependent Claim
38 words
The method of claim 1 , wherein determining the histogram comprises calculating a ratio of a number of inter frames having the respective motion intensity levels to a number of all inter frames constituting the input video data.
Claim 4
Dependent Claim
28 words
The method of claim 1 , wherein the motion intensity levels are determined by using motion compensation values of respective predetermined sized blocks included in an inter frame.
Claim 5
Dependent Claim
39 words
The method of claim 1 , wherein determining the motion intensity levels comprises calculating a ratio of a number of blocks whose motion compensation values are zero to a number of all of blocks included in an inter frame.
Claim 6
Dependent Claim
30 words
The method of claim 1 , further comprising: dividing a video stream into at least one video data; selecting the input video data among the at least one video data.
Claim 7
Dependent Claim
40 words
The method of claim 4 , wherein the determining the motion intensity levels comprises quantizing the ratio of the number of blocks whose motion compensation values are zero to the number of all of blocks included in an inter frame.
Claim 8
Dependent Claim
21 words
The method of claim 5 , wherein the dividing a video stream is performed by using a scene cut detection algorithm.
