Abstract

Disclosed is a system that includes a two-dimensional user interface for relevance-based instantaneous preview of retrieved videos. In the two-dimensional user interface, the vertical position of the mouse pointer determines the minimum relevance of interest (i.e., the threshold that determines which frames are to be retrieved), and the horizontal position along the time bar corresponds to the time in the video (as in a conventional instantaneous preview). It provides an intuitive and time-efficient way to review the search results interactively, and also enables the user to adaptively determine the minimum relevance of interest for each retrieved video according to the quality of the search results.

A two- retrieved videos

Disclosed is a system that includes a two-dimensional user interface for relevance-based instantaneous preview of retrieved videos. It provides an intuitive and time-efficient way to review the search results interactively, and also enables the user to adaptively determine the minimum relevance of interest for each retrieved video according to the quality of the search results.

    In a video retrieval system, a query-based search typically returns multiple results, which then need to be reviewed by the user. Typically, the results are returned as a ranked list (of either the videos themselves or the relevant frames within the videos) that is sorted in order of decreasing relevance, and reviewing the results one by one is time-consuming and inefficient.

    The disclosed system uses a two-dimensional user interface that provides an efficient way to review the search results. In this user interface, the vertical axis corresponds to the relevance score, and the horizontal axis corresponds to the time in the video. In one embodiment, the user first sets the desired minimum relevance score of interest (i.e., the threshold that determines which frames are to be retrieved) by fixing the vertical coordinate of the mouse (e.g., with a mouse click). The user can then move the mouse in the horizontal direction (e.g., from left to right) to preview all video frames

with relevance score above the threshold. For instance, with a very low threshold (i.e., a lo...
