摘要： Method and apparatus for controlling example-based image manipulation A method and apparatus for controlling example-based image manipulation are disclosed where selection of example imagery and workpiece imagery is done with a pointing device (605)and an act of motion thereof. For increasing the efficiency of controlling, selection of an image characteristic to be transferred is derived from an interaction sensed on a second input device(603, 611, 612, 613, 614) during a time interval of the act of motion of the pointing device(605).

摘要： The invention proposes a new motion layer extraction method using reference layer mosaics. One motivation is to work with distant images (whose motion in between is more discriminative) while reducing the number of pairs of images to be handled benefiting from the fact that layer mosaics represent the video sequence in a compact way. In this model, not only extracted layer supports for mosaicing are used but also layer mosaics for motion segmentation. In the proposed approach, instead of linking temporally many images pairs from the sequence, the currently processed original image is linked temporally with two sets of motion layer mosaics only. Thus a new image-to-mosaic data term replaces the usual image-to-image motion data term in the objective classification function.
摘要翻译：本发明提出了使用参考层马赛克的新的运动层提取方法。一个动机是与遥远的图像（其间的运动更具有歧视性）一起工作，同时减少由于层马赛克以紧凑的方式表示视频序列的事实而受益处理的图像对的数量。在该模型中，不仅使用用于镶嵌的提取层支持，而且还使用用于运动分割的层马赛克。在所提出的方法中，代替在时间上链接许多图像对与序列，当前处理的原始图像在时间上与两组运动图层马赛克相关联。因此，新的图像到马赛克数据项替代了客观分类函数中的通常的图像到图像运动数据项。

摘要： The invention relates to a device and method for online storage, to a device and method for searching for similar content, to a transmission device and method, and to a receiving device and method. Encrypted data is recorded at an online service provider. With the encrypted data, encrypted hashing data is recorded with a public key, and the content to be recorded with the encrypted hashing is encrypted, thus making it possible to advantageously prevent data duplication at the online service provider while maintaining the privacy of the users of the service. In order to search for similar content having multimedia reference data, marks are also recorded at the service provider. In order to limit the number of false positives returned, the mark can also contain a search mark and/or an encrypted selection mark.
