Abstract: The present disclosure relates to a method for transporting and distributing data (2) between a baseband, BB, unit (3) and two or more radio units (4) comprised in a communications network (1) arranged to cover a service area (6). The method comprises defining (S1) a logical grid of beams matrix, GoB, (5) associated with a carrier frequency band (B0, B1, B2, B3, B4, B5, B6, B7) of the communications network (1), wherein the GoB (5) comprises a set (S) of beam indices (BI), and partitioning (S2) the set (S) of beam indices into disjoint subsets (DS1, DS2, DS3, DS4) of at least one beam index (BI) each.

Abstract: Method and apparatus for demosaicing a mosaic pattern of a color picture. To improve the picture quality, especially in case of a non-uniform mosaic pattern, a kernel of the mosaic pattern is selected, and the pixel values of the kernel are multiplied by coefficients that comply with a non-linear bi-dimensional interpolation algorithm. Additionally the pixels of the selected kernel may be multiplied by sharpening coefficients that comply with a derivative of the non-linear bi-dimensional interpolation algorithm.

Abstract: The method of reducing the size of an initial image into a final image, each image being formed by a matrix of ordered pixels, each pixel being characterised by a characteristic quantity (Cn), the reduction being effected by a ratio P/Q with P and Q integers and Q not a multiple of P, comprising a pixel decimation step, in which the following steps are implemented: —effecting a partitioning of the initial image into groups of pixels; —allocating, successively to each group of pixels n of the initial image, a coefficient ?n the coefficients of the groups of pixels forming an arithmetic sequence of ratio P in Z/QZ defined by the recurrence relationship ?n+1??n+P(Q); —selecting only the groups of pixels whose coefficient allocated is a number less than P?1; —decimating the groups of pixels not selected: and—forming the final image of reduced size solely from the groups of pixels selected, each pixel in the groups of pixels selected being characterised by the filtered characteristic quantity (C?n).

Abstract: The method provides the identification, in a succession of acquired images each formed from a matrix of pixels, of a following sub-image extracted from a following acquired image corresponding to a prior sub-image extracted from a prior acquired image. The method comprises the steps of: —calculating, for the prior sub-image, at least one distribution of a characteristic quantity of each pixel for blocks forming a predefined partitioning of the sub-image; —calculating the same distribution for at least two would-be sub-images of the second format extracted from the following acquired image; and—determining the corresponding following sub-image from among the would-be sub-images, as the sub-image where the or each calculated distribution has the highest correlation with the same calculated distribution for the prior sub-image.
