A content-adaptive video preview system (100) allows to go faster through a video than existing video skimming techniques. Thereby, a user can interactively adapt (S1) the speed of browsing and/or the abstraction level of presentation.

According to one embodiment of the invention, this adaptation procedure (S1) is realized by the following steps: First, differences between precalculated spatial color histograms associated with chronologically subsequent pairs of video frames said video file is composed of are calculated (S1a). Then, these differences and/or a cumulative difference value representing the sum of these differences are compared (S1b) to a predefined redundancy threshold (S(t)). In case differences in the color histograms of particular video frames (302a-c) and/or said cumulative difference value exceed this redundancy threshold (S(t)), these video frames are selected (S1c) for the preview. Intermediate video frames (304a-d) are removed and/or inserted (S1d) between each pair of selected chronologically subsequent video frames depending on the selected abstraction level of presentation. Thereby, said redundancy threshold value (S(t)) can be adapted (S1b′) for changing the speed of browsing and/or the abstraction level of presentation.

In a similar face retrieval system for retrieving an image photographing a face similar to a face detected from a retrieval query image from a retrieval target image group by using an image photographing a human face as the retrieval query image, whole image features as features representative of background information are extracted from each whole area of an each image of a retrieval target image group, to calculate a degree of similarity through comparison with each set of whole image features, and an image having a degree of similarity not lower than a certain value and having a lower retrieval result order from retrieval results. It is possible to efficiently retrieve the same person playing in different scenes by utilizing different features for a retrieval process and a filtering process.

A system and process for navigating unstructured or loosely structured image sets on a display screen is presented. These image sets are navigated by grouping each image thereof into clusters and arranging the clusters in a left-to-right or up-and-down manner. A set number of the clusters are displayed to a viewer. The viewer can then scroll through and select another cluster in the arrangement as desired. Within a cluster, images are arranged in a grid in a sequence order based on a sequence number assigned to each in the clustering procedure. The viewer is also able to zoom into a selected cluster to, in effect, successively form smaller sub-clusters until only a single image is displayed in a cluster under consideration. In addition, the viewer can zoom out again in a similar manner.

An image processing apparatus capable of automatically adjusting the enlargement ratio and the position of images and to display the noticed areas of all selected images is disclosed. When a two image display mode is selected, an image previously displayed (a first image) and an image to be displayed in the two image display mode (a second image) are loaded from a memory into a display controlling unit and a correction value calculating unit. The display controlling unit performs enlarging and moving operations with respect to the first image and the second image simultaneously. The correction value calculating unit searches for an area in the second image (a corrected area) most resembling an enlarged area in the first image so as to enlarge the corrected area in the second image. The images processed by the display controlling unit are transmitted to an image display memory.

The invention discloses a ship monitoring video key frame extraction method based on a two-way GRU and an attention mechanism, comprising the following steps: step S1: training a two-way GRU and an attention mechanism model by using a large number of seaside ship monitoring video data sets. Step S2, extracting key frames from ship monitoring video by using trained two-way GRU and attention mechanism model, and providing a set of key frames for quickly retrieving ship. By adopting the technical proposal of the invention, the key frames are extracted and applied to the ship monitoring video, a large number of redundant video frames are eliminated, efficient search and browsing of ship events are provided, and the overhead of video storage is saved. At the same time, two-way GRU and attentionmechanism are used to model the relationship between the video frames, and the temporal information is fused into the model, and the information at each time is given different weight, that is, eachtime gives different attention degree, so that the key frame set which is more consistent with human semantics can be obtained.

Method and system for bartering between trade parties each having one or more items available for barter, via a communications network. Items available for trade are listed and the parties can browse and search the lists to locate items they want to acquire and items they have available to trade, and create a barter listing or link between items, each link including one or more items a party wants to acquire, and one or more items the party has available to trade. The links are analyzed to determine when a potential trade can be completed between multiple parties to provide each party with one or more items they want from another party involved in the potential trade. If so, the parties involved in the potential trade are notified of the possibility of realizing the trade to enable the parties to approve or reject the potential trade.

For courses that deal with media content, such as sound, music, photographic images, hand sketches, video, conventional techniques for automatically evaluating and grading assignments are generally ill-suited to direct evaluation of coursework submitted in media-rich form. Likewise, for courses whose subject includes programming, signal processing or other functionally-expressed designs that operate on, or are used to produce media content, conventional techniques are also ill-suited. Instead, it has been discovered that media-rich, indeed even expressive, content can be accommodated as, or as derivatives of, submissions using feature extraction and machine learning techniques. In this way, e.g., in on-line course offerings, even large numbers of students and student submissions may be accommodated in a scalable and uniform grading or scoring scheme. Likewise, large collections of coursework submissions (whether or not graded or scored) or media content more generally, may be efficiently browsed and grouped using techniques described herein.
