摘要:
The process of compressing video requires the calculation of a variety data that are used in the process of compression. The invention exploits some or all of these data for purposes of content detection. For example, these data may be leveraged for purposes of commercial detection. The luminance, motion vector field, residual values, quantizer, bit rate, etc. may all be used either directly or in combination, as signatures of content. A process for content detection may employ one or more features as indicators of the start and/or end of a sequence containing a particular type of content and other features as verifiers of the type of content bounded by these start/end indicators. The features may be combined and/or refined to produce higher-level feature data with good computational economy and content-classification utility.
摘要:
A video indexing system analyzes contents of source video and develops a visual table of contents using selected images. A system for detecting significant scenes detects video cuts from one scene to another, and static scenes based on DCT coefficients and macroblocks. A keyframe filtering process filters out less desired frames including, for example, unicolor frames, or those frames having a same object as a primary focus or one primary focuses. Commercials may also be detected and frames of commercials eliminated. The significant scenes and static scenes are detected based on a threshold which is set based on the category of the video.

摘要:
A cleaning composition comprising at least one strong acid, the composition additionally comprising an oily material and at least one electrolyte, the oily material having a viscosity of 100 cSt maximum@20° C., preferably less than 20 cSt maximum@20 C. and a specific gravity less than that of water, the oily material optionally comprising fragrance soluble therein. In such a composition, the strong and often potentially hazardous odor generally characteristic of such cleaners is substantially reduced or even completely eliminated.
摘要:
A malodor counteracting composition comprising at least one compound of formula (A) and at least one compound of formula (B) wherein n, X, Y and R1 to R4 are as defined in the description.
摘要:
Means of disseminating simultaneously into an atmosphere a volatile antifungal fragrance and a non-antifungal fragrance, the two fragrances being disseminated from two different sources such that the non-antifungal fragrance is more olfactively perceptible than the antifungal fragrance. Typically the non-antifungal fragrance is present in the packaging of the antifungal fragrance.
摘要:
An apparatus for disseminating volatile liquid such as fragrance or insecticide into an atmosphere from a reservoir, the transfer to atmosphere being at least partially achieved by means of a transfer member having external capillary channels. The volatile liquid is one in which at least 30% by weight of the materials therein have a molecular weight of 175 maximum, and which has a surface tension of less than 40 dynes/cm. The transfer member is of plastics material having a surface energy of less than 45 dyne/cm. The combination allows for particularly efficient dissemination.
