    摘要: A method for decomposing a digital image at resolution R and MR into a set of spatial sub-bands of resolution R and MR where MR>R and where the high-band at resolution MR is calculated by subtracting the filtered and up-sampled image at resolution R from the image at resolution MR and where the spatial low-band at resolution R is calculated by adding the filtered and down-sampled spatial high-band to the image at resolution R and where a rational factor for up-and down-sampling M is determined by the resolution ratio.

    摘要: A method is disclosed for decomposing a set of even and odd pictures into low-band and high-band pictures respectively in a image decomposing unit, in which the even picture is used by at least two prediction motion compensators on which the output signal of each prediction motion compensator is scaled according to the number of prediction motion compensators. The method includes calculating the high-band picture by subtracting from the odd picture the scaled motion-compensated signals and using the high-band picture in the at least two update motion compensators, the output signal of each update motion compensator being scaled according to the number of update motion compensators. Finally, the low-band picture is calculated by adding the scaled update motion-compensated signals to the even picture.

    摘要: A multi-frequency microwave antenna (1) of the microwave image reconstruction system senses a signal which passes through an analogue connection (6) to a Dicke null-balancing radiometer (7) which detects sequentially the signal contributions at the different frequencies of the multi-frequency antenna of the system. The resulting sequential analogue signals from the radiometer are directly related to the brightness temperatures at the corresponding frequencies, and these brightness temperatures are directly related to a real intra-body temperature distribution. The system uses a PC (5) and comprises a mean to reconstruct a one-dimensional profile of real intra-body temperatures from the brightness temperatures via the outputs from the analogue-to-digital converter (15). The algorithm of this system uses “large” over-complete dictionaries which, on the one hand reflect the variability of potential temperature profiles and on the other hand incorporate as much a-priory information as possible, in order to provide reliable image reconstruction.

    摘要: The invention relates to a video coding method of exploiting the temporal redundancy between successive frames in a video sequence. A reference frame, called I-frame, is first approximated by a collection of geometric features, called atoms. The following predicted frames called, P-frames, are approximated by the geometric transformations of the geometric features (atoms) describing the previous frame. Preferably, the I-frame is approximated by a linear combination of N atoms (formula), selected in a redundant, structured library. They are indexed by a string of parameters representing the geometric transformations applied to the generating mother function g(x,y) and the cn are weighting coefficients.
