Abstract: The invention relates to a method and a device for producing a thermal map of an area, wherein the thermal map is generated by a combination of two thermal images of different properties, and both thermal images comprise pixels associated with the area and have been recorded by satellites. The two thermal images are recorded at different times using different recording devices. Furthermore, a radiometric precision of the first thermal image is higher than that of the second thermal image, and a spatial resolution of the second thermal image is higher than that of the first thermal image. The two thermal images are used to determine a measurement value offset of a first pixel group belonging to the second thermal image and spatially associated with the area, and then corrected absolute measurement values of the pixels belonging to the second thermal image and spatially associated with the area are determined. A precise thermal map of the area is then created on this basis.

Abstract: The coding of a media signal is rendered more efficient by describing the media signal using a sequence of samples and sequentially encoding this sequence by selecting, for a current sample, a set of quantization levels out of a plurality of quantization level sets depending on indices encoded into the data stream for previous samples of the sequence of samples, quantizing the current sample onto one level of the set of quantization levels, and encoding a quantization index to the one level for the current sample into the data stream. In other words, scalar quantization of the individual samples of the sequence of samples is used, but it is rendered dependent on quantization indices encoded into the data stream for previous samples of the sequence of samples.

Abstract: An improved concept for coding sample values of a spectral envelope is obtained by combining spectrotemporal prediction on the one hand and context-based entropy coding the residuals, on the other hand, while particularly determining the context for a current sample value dependent on a measure of a deviation between a pair of already coded/decoded sample values of the spectral envelope in a spectrotemporal neighborhood of the current sample value. The combination of the spectrotemporal prediction on the one hand and the context-based entropy coding of the prediction residuals with selecting the context depending on the deviation measure on the other hand harmonizes with the nature of spectral envelopes.
