Abstract: A method for processing image data having noise and information, including: acquiring input raw image data having pixels of an image sensor used to take the image data, processing the input data, and outputting processed image-output data. The step of acquiring input data includes acquiring an input-noise model from the input data, and the step of processing the input raw image data includes a preprocessing operation and determining an output-noise model adapted to reflect noise in the output data, and producing output raw-image data consistent with the output-noise model, and the step of outputting the processed image data includes storing and/or transmitting the output raw image data and the output-noise model, which together form the output data, in a manner linking the output raw image data to the output-noise model, thereby allowing processing of the output data, as input data, such that the processing is adapted for pipeline processing.

Abstract: A method for steganographic processing and compression of image data with negligible information loss, wherein said image data comprises noise and information. The method includes the steps of: acquiring image data to be processed and/or compressed, storing and/or transmitting the image data, and preparing the acquired image data for compression. The preparation step includes determining an input noise model and corresponding parameters adapted to reflect noise created by an image sensor used to capture said image data, and removing, with negligible information loss, noise from the acquired image data by use of the input noise model such as to produce noise-reduced image data.

Abstract: A system and method to compress image data by first identifying the device and settings with which the image data was generated, and then optimizing the compression accordingly. A catalogue that associates imaging devices and settings to compression parameters is generated, so that when an image needs to be compressed, the system will identify the device and settings and extract compression parameters from the catalogue. These parameters are used during compression to achieve higher compression performance and optionally to normalize the compressed data as to make it more homogenous for further processing.

Abstract: A robust gas sensor can be manufactured in a simple manner and at low cost, and have no movable optical components. A measured gas cell (3) has a wall defining a cylindrical space with a measured gas inlet. The measured gas cell (3) is limited in the longitudinal axial direction by a reflective, flat first cover element (1) and by a reflective, flat second cover element (5) arranged at a spaced location from and in parallel to the first cover element (1). The height of the measured gas cell (3) corresponds approximately to 1 to 3 times the diameter of the cover elements (1, 5). The second cover element (5) accommodates a radiation source (6) and two detector elements (23, 24) with at least one measuring detector and one reference detector. The radiation source (6) is arranged displaced by 30% to 60% of the radius of the second cover element (5) from the center of the second cover element (5).

The reflecting measuring cuvette is designed as an annular space (1) between a first, inner cylinder section (6) and a second, outer cylinder section (2) that is concentric thereto. The annular space (1) is limited by a cover element (5) and a bottom element (7) arranged at a spaced location therefrom in the direction of the longitudinal axis. The cover element (5) is permeable to the measuring gas. The bottom element (7) accommodates the radiation source (8).
