摘要： For time-sequential segment tracing, also of moving regions, a method of segmenting time-sequential images of a picture signal, in which, within an image, the image is split up into regions during its segmentation, and in which adjacent pixels having similar luminance and/or chrominance values are associated with a region is characterized in that it is attempted in time-sequential images to retrace regions of an image I.sub.n in a subsequent image I.sub.n+1 by performing a motion estimation of the regions of the image I.sub.n, in that the new position of the region in the image I.sub.n+1 is determined with reference to the motion vectors determined for each region by means of the motion estimation, in that subsequently the displaced regions are adapted to the image contents of the image I.sub.n+1, and in that pixels of the image I.sub.n+1 not covered by these adapted regions are added to one of these regions or to newly formed regions.

摘要： To achieve an enhanced data reduction, a method of fractal image coding, in which method an image to be encoded is divided into range blocks which do not overlap and jointly cover the image contents completely, in which domain blocks comprising areas of the image contents in their original form or in a transformed form are generated from the image contents, and all areas of the image contents are covered by at least one domain block, for each range block the domain block most similar to the range block being searched, and the addresses of the domain blocks found as the most similar and possibly the transform functions used for their generation being transmitted instead of the data of the range blocks, is characterized in that, in a sequence of images, the fractal image coding performed exclusively within the images is only performed with basic images comprised in the image sequence at selectable time intervals, in that, for intermediate images provided between the basic images, the same range and domain block division is used as for the basic images, and in that, individually for each range block in a search area, that domain block is searched in an intermediate image which was found as the most similar in the previous image for the range block of the same position, and in that, if said domain block is found in the search area, the displacement vectors of this block relative to the domain block found as the most similar in the previous image are transmitted instead of the address and possibly the transform function.

摘要： A method and arrangement for computing values of pixels arranged outside a 2-dimensional scanning raster of pixels having pixel values of a digital picture signal, where at least 3 of 4 reference pixels arranged around the searched pixel are determined for computing a searched pixel value s.sub.i (x.sub.0 +.DELTA.x,y.sub.0 +.DELTA.y). A polynomial p(x,y) in the form c.sub.m-1 x.sup.am-1 y.sup.bm-1 +c.sub.m-2 x.sup.am-2 y.sup.bm-2 + . . . +c.sub.2 x+c.sub.1 y+c.sub.0 is constituted corresponding to their values. Next, k 1st derivatives .delta.s(x,y)/.delta.x in the x-direction and .delta.s(x,y)/.delta.x in the y-direction are formed from at least one of the reference pixel values. Then, a matrix is formed whose elements consist of the values of the basic functions x.sup.am-1 y.sup.bm-1,x.sup.am-2 y.sup.bm-2, . . . x,y,1 of the polynomial at at least 3 of the reference pixels and the k 1st derivatives .delta.p(x,y)/.delta.x in the x-direction and .delta.p(x,y)/.delta.y in the y-direction of the basic functions at at least one of the reference pixel values. The basic functions are allocated to a reference pixel or a 1st derivative of a reference pixel in one matrix row. An inverse or pseudo-inverse matrix is formed from the matrix by means of inversion and multiplied by an observation vector for determining the polynomial coefficients c.sub.m-1 through c.sub.0. The polynomial coefficients are introduced into polynomial p(x,y) and the new pixel value s.sub.i (x.sub.0 +.DELTA.x,y.sub.0 +.DELTA.y) is computed from the function value of the polynomial p(.DELTA.x,.DELTA.y) at the location (.DELTA.x, .DELTA.y).

摘要： A circuit for converting samples of data received at a high sampling rate into data samples at a low sampling rate integrally related to the high sampling rate and with the low rate samples synchronized with the high rate samples without a complex phase control apparatus. A memory stores and transfers data under control of write and read address signals. The read address signals are derived by combining the write address signals with a difference address signal generated by a circuit including a modulo counter with a modulus corresponding to the integral ratio between the high and low sampling rates, a first sample-and-hold circuit for storing the count of the modulo counter and supplying its count to an allocating circuit which generates the difference address signal and supplies same to a combining circuit. A decoder controlled by the modulo counter supplies a clock signal at the low sampling rate to a second sample-and-hold circuit fed with data from the memory. The second sample-and-hold circuit outputs synchronized data at the low sampling rate.

摘要： For fractal image coding optimal scaling factors for the image contents in the domain blocks are searched. Each image is divided into analysis blocks, which jointly represent the whole image. The analysis blocks are embedded in analysis regions, which contain besides the analysis blocks areas with a predetermined signal value. Also, comparison regions are formed, which contain at least parts of the image and which have the same size as the analysis regions. The analysis regions and the comparison regions are Fourier transformed. The transformed signals are converted logarithmically. The logarithmized signals are again Fourier-transformed. One of these signals is converted in its conjugate-complex form before both signals are multiplied. The product is normalized, so that it no longer contains amplitude information. Then the signal is subjected to an inverse Fourier-Transformation. If the signal has been logarithmized then it is de-logarithmized. The maximum of this signal then indicates the optimum frequency factors. By a further inverse Fourier-transformation the maximum of the signal indicates the optimal scaling factor that is searched.
