Abstract

A video searching method includes: providing a database for storing the data of a video, wherein the data of the video includes the colors of at least a key frame; providing a searching interface for an user uploading a key picture; providing a recording unit for recording the colors of the key picture; providing a performing unit for comparing the colors of the key frame and the key picture to judge whether a similar color exists; the performing unit computing the value of the colors if there exists a similar color; the performing unit sifting the video by comparing a threshold value and the value of the colors; and the performing unit sorting the video by the value of the colors to obtain a result list. By comparing the value of the colors between the key picture and the key frame, the result list is simply and quickly obtained.

Dependent claims

A video searching method, applied in a computer comprising a database, a searching interface, a recording unit, a performing unit, a display interface, an uploading interface, a picking unit and a conversion unit which are electrically connected to each other, the video searching method comprising:

storing in said database at least one video therein, wherein each the video comprises at least one key frame, and each the key frame comprises a first source color;
uploading a key picture via said searching interface, wherein the key picture comprises a second source color;
recording in said recording unit the second source color of the key picture;
in said performing unit comparing the second source color and the first source color, and thereby determining a similar color count between the key picture and each the key frame, and a proportion of the similar color count in each the key frame;
if the similar color count and the proportion of the similar color count are larger than zero, the performing unit generating a statistical list comprising a maximum of the similar color count, a maximum of the proportion of the similar color count, an average value of the similar color count and an average value of the proportion of the similar color count of each the video;
the performing unit sifting out at least a sifted video from the statistical list according to the maximum of the similar color count and the maximum of the proportion of the similar color count;
after sifting out the sifted video from the statistical list, the performing unit sorting the sifted video in order by the average value of the similar color count and the average value of the proportion of the similar color count to obtain a result list;
and
displaying the result list via said display interface.
