摘要:
A method of generating a summary of an audio/visual data stream is provided, the data stream comprising a plurality of consecutive frames having audio and visual properties. A plurality of shots of an audio/visual data stream are detected (step 204). A plurality of segments of the audio/visual data stream are determined (step 206), each segment comprising a plurality of the shots of the data stream having similar visual properties. A segment of the determined plurality of segments is selected (step 208). For each shot of said selected segment of said data stream, the audio in a plurality of consecutive frames which occur after the end of said shot is extracted (step 210). At least one of the shots is selected based on the extracted audio (step 212). A summary is generated to include the selected at least one of the shots (step 214).

A sequence of a plurality of images to be displayed as a slide show whilst accompanied by an audio item is generated by extracting (209) at least one feature of an audio item, such as pace, —extracting (203) at least one feature of each of a plurality of images; and determining (215) the next image to generate a sequence of selected ones of the plurality of images to be displayed whilst accompanied by the audio item on the basis of the extracted at least one feature of the audio item and on the basis of the extracted at least one feature of the image.

A method for controlling a second modality based on a first modality is provided. The method comprises the steps: providing a first modality comprising time-dependent characteristics and a second modality capable of changing its appearance over time; automatically determining changes in the appearance of the second modality based on the time-dependent characteristics of the first modality; adjusting a smoothing degree by means of a user input device; and adapting the determined changes in appearance of the second modality based on the smoothing degree and on boundaries present in the time-dependent characteristics of the first modality to arrive at resulting changes in the appearance of the second modality.
摘要:
A method of selecting at least one representative image from a plurality of images, the method comprising the steps of: dividing (201) the plurality of images into clusters according to a predetermined characteristic of the content of the plurality of images; selecting (203) at least one of the clusters based on the number of images in each of the clusters; and selecting (205) at least one image from the selected at least one cluster as the representative image.
摘要:
A summary comprising a plurality of selected segments of the content item is presented to a user (step 202) and a user input is received (step 204). The non-selected segments located between a previously presented segment and the segment being presented at the time of receiving said user input are determined (step 206) and each non-selected segment is assigned a ranking value (step 208). At least one non-selected segment is presented (step 210). Presentation of the selected segment being presented at the time of receiving the user input is resumed (step 212).
摘要:
A method for determining a value of an attribute to be associated with an image, the method comprising the steps of: determining saturation of each of a plurality of pixels of an image; selecting a set of a plurality of pixels from the pixels of the image having a saturation above a predetermined level; determining a value of an attribute on the basis of the selected set of pixels; and associating the determined value of the attribute with the image.

A system computes a combined dominant color descriptor (DCD) of a plurality of images (IM 1, IM 2, IM n). The system comprises an input 206 for receiving a plurality of respective dominant color descriptors (DCD 1, DCD 2, DCD n) of respective images of the plurality of images (IM 1, IM 2, IM n). The system further comprises means 202 for generating a collection of generated color values (IM) based on dominant colors included in the received dominant color descriptors (DCD 1, DCD 2, DCD n), and means 204 for computing at least one dominant color of the collection of generated color values (IM) for inclusion in the combined dominant color descriptor (DCD). In the collection, at least one generated color value is included representing a dominant color in one of the received dominant color descriptors.
摘要:
A device and a method for playing audio-video content (205) during which loss of attention of a user (192) is detected. Loss of attention of the user generates at least one attention loss marker (255) that is stored in an attention loss storage unit (210). The user may revert playback to a point in time corresponding to the attention loss marker using a user interface unit (190). By storing markers corresponding to points of attention loss by the user and requiring explicit user input, the attention loss detector may detect attention loss with an accuracy lower than would otherwise be the case. Optionally, storing of the attention loss markers may be made conditional upon a content analysis unit (420), such as a commercial block detector. An attention loss marker indication (260) may be made visible to the user to indicate that at least one attention loss marker has been detected.
摘要:
Techniques for guaranteeing payment to a seller of a commodity purchased by a buyer are described. A selection of a sales proposal for purchasing the commodity from the seller is received. The sales proposal specifies the conditions under which the commodity will be delivered to the buyer. The seller is then notified that the sales proposal has been selected by the buyer, and a payment agreement is provided to the seller. The payment agreement specifies financial terms under which a financial institution guarantees payment to the seller on behalf of the buyer for future deliveries of the commodity in accordance with the sales proposal.
摘要:
The present invention relates to a an active pillow system and a method for manipulating a person's resting conditions, wherein the actual resting conditions of the person are determined by a sensor unit, an actigraph, a temperature sensor and/or a humidity sensor for instance, and wherein an acoustic synthetic jet cooling mechanism, is triggered by the determined actual resting conditions for manipulating the person's resting conditions.
