    • It is an object of this invention to detect a similar picture at high speed with high accuracy from a large-scale picture archive. Previously, a frame is extracted from each picture in a picture archive at fixed time intervals, an image feature quantity is extracted from each extracted frame, and the extracted image feature quantities are clustered, thereby constructing a clustered feature quantity database. A frames search section performs a similar frame search not only for a leading frame of a query picture but also for a subsequent frame, by using the database. A search result integration section checks whether there is a sequence across a plurality of search results and outputs, as a picture similar to the query picture, a segment which is confirmed to be continuous for a certain length or more.
    • 本发明的目的是从大规模的图像存档中以高精度从高速度检测相似的图像。 以前,以固定的时间间隔从图像存档中的每个图像提取帧,从每个提取的帧中提取图像特征量,并且提取的图像特征量被聚类,从而构建聚类特征量数据库。 通过使用数据库,帧搜索部分不仅对查询图像的前导帧进行类似的帧搜索,而且对后续的帧执行类似的帧搜索。 搜索结果集成部分检查在多个搜索结果中是否存在序列,并且作为类似于查询图像的图像输出被确认为连续一段或多于一个的段。
