摘要： The method comprises the following steps: detection of non-static pixels in a picture, with respect to a preceding picture, calculation of the number of non-static pixels in the picture, calculation of the variation, in absolute value, of the number of non-static pixels for the picture, corresponding to the difference between the number of non-static pixels of the picture and that of the preceding picture, detection of a peak in the variation, the picture relative to the variation leading to the peak then being the first picture of the new scene. The applications relate to video coding, for example video stream switches.

摘要： The present invention relates to a device and a process for motion-compensated recursive filtering and a corresponding coding system. The device comprises in particular a blockwise motion estimation module [(2)], means [(3)] for determining a recursivity noise level (σrec), a module (4) for calculating a prediction error (ε), a module [(5)] for calculating a recursivity coefficient (α) as a function of the recursivity noise level and of the prediction error, means [(6)] for calculating a motion-compensated image and means of filtering [(7, 8)] producing a weighting, by the recursivity coefficient, of the current input image and of a filtered and motion-compensated image stored previously. The device also comprises means [(3)] for determining an immobility noise level (σimm), and an assembly [(11, 12)] for processing zones constituting partitions of the blocks employed for the motion estimation, zeroing the motion vectors (d) associated with the zones in which the FDs are below a threshold dependent on the immobility noise level.

摘要： The invention relates to a device for pre-processing before encoding of a sequence of images including: means of storing the current frame and at least two preceding frames, means of defining a vicinity for each point of the current frame and for each corresponding point in the two preceding frames, means of measuring the motion of the current point relative to its position in the two preceding frames so as to detect whether the current point is in motion or in a static zone. According to the invention, the device includes: means of performing a spatial smoothing on the current point if the current point is in motion, means of performing a space-time smoothing if the current point is located in a static zone.

摘要： A process for addressing cells of a plasma panel includes the step of coding the grey levels NG1 and NG2 relating to an item of information regarding the luminance of two cells situated in the same column and in two adjacent lines I and I+1. The grey levels NG1 and NG2 are coded as a first control word corresponding to a common value VC and as a second control word and a third control word corresponding to specific values, VS1 and VS2. The coding is such that, NG1=VS1+VC and NG2=VS2+VC. The process further includes the step of transmitting the bits of the first control word on the column inputs by simultaneously addressing the two lines I and I+1 in respect of the selection of the corresponding cells.
