摘要： An image retrieval method includes reading from a first database a first image group mapped to an object as a retrieval target, and extracting an image feature quantity of a plurality of images of the first image group. A second image group mapped to an object as a search key is read from a second database and an image feature quantity of a plurality of images of the second image group is extracted. Similarity is determined between the first image group and the second image group, based on the image feature quantity of the plurality of images of the first image group and the image feature quantity of the plurality of images of the second image group. On an output device, as retrieval results, the plurality of images of the first image group are displayed in order of similarity of the object as the retrieval target based on determined similarity.

摘要： Embodiments disclose a method and apparatus for detecting a camera motion type in a video, the method including: estimating a first zoom motion parameter between adjacent frames in the video; estimating a second zoom motion parameter between frames having an interval of a preset number in a corresponding video segment when the first zoom motion parameter meets a first preset condition; and identifying the camera motion type of the video segment as slow zoom when the second zoom motion parameter meets a second preset condition. With the embodiments of the invention, the motion type of a camera in the video can be detected more effectively and accurately.
