摘要： The present invention relates to a method for classifying a signal (S). An intermediate signal (IS) is decimated in order to obtain a processed signal (PS) as a new intermediate signal (IS). A processed signal (PS) is compared with respect to the signal (S) to be classified to thereby generate comparison data (CompDAT). Based on the comparison data (CompDAT) said signal (S) to be classified is classified, thereby classification data (ClassDAT) are generated.

摘要： A method for picture improvement is proposed, comprising the steps of receiving (S1) said image data (ID) as input data (I), classifying and/or identifying (S2) the content of said image data (ID), thereby generating image content classification/identification data (ICCI) from said image data (ID), improving and/or processing (S3) said image data (ID) using said image content classification/identification data (ICCI), thereby generating and/or outputting (S4) improved image data (IID) as output data (O).

摘要： A method for video content classification is proposed, wherein said video comprises a sequence of images (I), each of said images (I) consisting of respective image data (ID), said method comprising:
generating a feature vector (FV) based on said image data (ID), wherein said feature vector is descriptive of temporal and/or spatial features of at least one of said images (I);
generating image content classification/identification data (ICCI) based on said feature vector (FV) and based on a trainable classification method; and
classifying said video content based on said image content classification/identification data (ICCI).摘要翻译： 提出了一种用于视频内容分类的方法，其中所述视频包括一系列图像（I），每个所述图像（I）由各自的图像数据（ID）组成，所述方法包括：基于 所述图像数据（ID），其中所述特征向量描述所述图像（I）中的至少一个的时间和/或空间特征; 基于所述特征向量（FV）生成图像内容分类/识别数据（ICCI），并且基于可训练的分类方法; 以及基于所述图像内容分类/识别数据（ICCI）对所述视频内容进行分类。

摘要： The present invention relates to the field of data compression. More particularly, the present invention relates to the pre-processing which is applied to a signal before it is encoded and to the post-processing of a signal after it is decoded. The present invention provides a pre-processor for signals to be encoded comprising a filtering device for filtering a signal with one or more filters and a providing device for providing information about the filtering process. The present invention further provides a post-processor for previously filtered, encoded and decoded signals comprising an information retrieving device for retrieving information about the filtering process and an inverse filtering device for inverse filtering the decoded signal based on the retrieved information.
摘要翻译： 本发明涉及数据压缩领域。 更具体地说，本发明涉及在其被编码之前应用于信号的预处理和对其进行解码之后的信号的后处理。 本发明提供一种用于要编码的信号的预处理器，包括用于利用一个或多个滤波器对信号进行滤波的滤波装置和用于提供关于滤波处理的信息的提供装置。 本发明还提供了一种用于先前滤波的，编码和解码的信号的后处理器，包括用于检索关于滤波处理的信息的信息检索装置和用于基于检索到的信息对解码信号进行反向滤波的逆滤波装置。
