摘要： The invention concerns a method of compressing and transmitting digital data, in particular images, at a constant bit rate, the method comprising the following steps: splitting input data into blocks of data, applying an orthogonal or bi-orthogonal transform (12) to each block, quantizing (14) the coefficients obtained by applying the transform, entropically coding (20) the quantized coefficients, temporarily saving the data resulting from coding in a buffer memory (18), removing a particular number of bits from the memory for each block of digital data, and adjusting the quantizing step by applying a control function (50) to obtain, after coding, a number of bits close to the number of bits removed from the memory for each block of data. The control function (50) takes account of the data bit rate measured for at least the preceding block.

摘要： The invention concerns a method for compressing data, in particular images, by transform, in which method this data is projected onto a base of localized orthogonal or biorthogonal functions, such as wavelets. To quantize each of the localized functions with a quantization step that enables an overall set rate Rc to be satisfied, the method includes the following steps: a probability density model of coefficients in the form of a generalized Gaussian is associated with each subband, the parameters α and β of this density model are estimated, while minimizing the relative entropy, or Kullback-Leibler distance, between this model and the empirical distribution of coefficients of each subband, and from this model, for each subband, an optimum quantization step is determined such that the rate allocated is distributed in the various subbands and such that the total distortion is minimal. As a preference, for each subband, the graphs of rate R and distortion D are deduced, from the parameters α and β, as a function of the quantization step and these graphs are tabulated to determine said optimum quantization step.

摘要： A scanning multispectral telescope comprises an optical architecture arranged so as to focus the image of an object in the vicinity of a photodetection assembly, the area of focus being an image plane. The photodetection assembly comprises a number of parallel rows of photodetectors, each row being dedicated to a particular spectral band, each spectral band being centred on a mean wavelength. The telescope comprises means for acquiring and analyzing the images obtained from the rows of photodetectors using a phase diversity algorithm. Finally, the telescope comprises optical or mechanical means arranged in such a way that at least one of the rows of photodetectors is offset by a fraction of the mean wavelength which corresponds to it on an axis perpendicular to the image plane.
