    • A compact image sequence descriptor (101), used for describing an image sequence, comprises a segment global descriptor (113) for at least one segment within the sequence, which includes global descriptor information for respective images, relating to interest points within the video content of the images. The segment global descriptor (113) includes a base descriptor (121), which is a global descriptor associated with a representative frame (120) of the image sequence, and a number of relative descriptors (125). The relative descriptors contain information of a respective global descriptor relative to the base descriptor allowing to reconstruct an exact or approximated global descriptor associated with a respective image of the image sequence. The image sequence descriptor (101) may further include a segment local descriptor (114) for a segment, comprising a set of encoded local feature descriptors.
    • 用于描述图像序列的紧凑图像序列描述符(101)包括用于该序列内的至少一个分段的分段全局描述符(113),该分段全局描述符包括与视频内容内的兴趣点有关的各个图像的全局描述符信息 的图像。 段全局描述符(113)包括基本描述符(121)和多个相对描述符(125),该基本描述符是与图像序列的代表性帧(120)相关联的全局描述符。 相对描述符包含相对于基本描述符的相应全局描述符的信息,从而允许重建与图像序列的相应图像相关联的精确或近似全局描述符。 图像序列描述符(101)可以进一步包括用于片段的片段局部描述符(114),其包括一组编码的局部特征描述符。

    • The invention relates to a method for producing a homogenous solution of a fluoropolymer, selected from fluoro-homopolymers and fluoro-copolymers and mixtures of various fluoro-homopolymers and/or fluoro-copolymers in a high boiling solvent, whereby (a) the fluoropolymer to be dissolved is dissolved in a mixture of at least two solvents, the first comprising a boiling point of less than 150°C, and/or a vapor pressure of over 5 hPa (at 20°C), and the second being a high boiling solvent comprising a boiling point at least 50 K higher than the first solvent and/or the boiling point thereof being selected so that the solvent mixture comprises a separation factor α of ≥1, and subsequently (b) the first solvent is substantially or completely removed from the mixture. The invention further relates to a method for producing suspensions of inorganic particles of a piezoelectrically and pyroelectrically active or activatable oxide in such fluoropolymer solutions and to the products of said method. The colorless fluoropolymer solutions and opaque white suspensions are suitable for producing laminar piezoelectric and pyroelectric coatings, in particular using doctor blade or screen printing methods.
