20080232687 | METHOD AND DEVICE FOR SELECTION OF KEY-FRAMES FOR RETRIEVING PICTURE CONTENTS, AND METHOD AND DEVICE FOR TEMPORAL SEGMENTATION OF A SEQUENCE OF SUCCESSIVE VIDEO PICTURES OR A SHOT - Exemplary embodiments are described in which is performed not only a shot detection (continuous recording with a camera) and an association of several key-frames to the shots, it then being possible for a subsequent scene recognition to be based on the grouping of shots into scenes. Rather, it is observed that a scene only relates to one event in a setting. Since both can change within a shot, not every scene boundary is at the same time also a shot boundary. In addition, not every shot is short enough, so that a reliable retrieval of different picture contents is not guaranteed. Therefore, exemplary embodiments are shown which are capable of defining sub-shots so that in principle, scene and shot boundaries are also sub-shot boundaries at the same time. Sub-shots furthermore include only video pictures with a small change in picture content. | 09-25-2008 |
20080316307 | AUTOMATED METHOD FOR TEMPORAL SEGMENTATION OF A VIDEO INTO SCENES WITH TAKING DIFFERENT TYPES OF TRANSITIONS BETWEEN FRAME SEQUENCES INTO ACCOUNT - The automated detection of scene boundaries supports the user in browsing a video. Establishing the similarity between two respective frame sequences is made by choosing and comparing respective key-frames from each frame sequence, which are temporally as far apart from each other as possible but lie outside gradual transitions. Additionally or alternatively, film grammar- and probability-based taking into account of all types of transitions with respect to their separating and/or merging effect on the frame sequences surrounding the transitions and a differently weighted incorporation of the effects of the different types of transitions into uniting frame sequences k into scenes is provided. Thus, all types of transitions are incorporated in determining frame sequence boundaries as scene boundaries with a corresponding weighting, both their separating and merging effect is taken into account, and this knowledge is introduced on a probability basis into the decision in existing scene detection methods. | 12-25-2008 |
20100260425 | Method and Device for the Automated Comparison of Two Sets of Measurement Values - A method and a device are for an automated comparison of at least two sets of measuring values. The measuring values of the two sets are assigned respectively to one class from a finite number of classes defined by indices so that a frequency distribution is defined respectively for each of the two sets, which frequency distribution indicates for each class a frequency of the measuring values assigned to this class. A distance measure reflecting a similarity or dissimilarity between the two sets of measuring values between these frequency distributions is calculated as a function of a final value of a first auxiliary value termed here match by way of example. The first auxiliary value match is calculated by an algorithm using two sets of variables in that, with a given maximum distance d | 10-14-2010 |

20130217748 | COSMETIC CLEANING AGENT - A cosmetic cleaning agent, comprises: in a cosmetic carrier: (a) greater than or equal to 12 wt % of a surfactant mixture comprising (i) at least one anionic surfactant and (ii) at least one zwitterionic/amphoteric surfactant in a weight ratio (i):(ii) of (2,5-3,5):1; (b) at least one cationic copolymer comprising (meth)acrylamide and dialkyldiallylammonium salts as the monomers; and (c) at least one opacifier and/or one pearlizer; wherein the quantities are based on the total weight of the cleaning agent. A method of producing a stable turbid and/or pearlescent cosmetic cleaning agent comprises: combining (a) at least one anionic surfactant and (b) at least one zwitterionic and/or an amphoteric surfactant to produce a surfactant combination; and combining, at room temperature, the surfactant combination with, (c) at least one cationic copolymer comprising (meth)acrylamide and dialkyldiallylammonium salts as the monomers, and (d) at least one opacifier and/or one pearlizer. | 08-22-2013 |
