Abstract: The present invention relates to molecular markers for detection, prognosis and follow up of Parkinson's disease (PD), wherein said molecular markers are one or more genes with altered expression pattern, or gene products thereof (RNA or protein). Genes which expression is upregulated or downregulated in PD patients are tools for early diagnosis of PD, for monitoring the progress of the disease and can serve as targets for screening new agents for treatment of PD.

Abstract: The invention relates to a method for interpolating a pixel from an intermediate line of a first field of a sequence of interlaced fields.

Abstract: An image to be interpolated is subdivided into a number of image blocks and a motion estimation technique is implemented to provide at least one initial motion vector for each of the image blocks. A modified motion vector is generated for each image block based on the initial motion vectors assigned to the individual image blocks. At least one additional image block is determined through which the motion vector assigned to the given image block passes at least partially, and the modified motion vector is generated as a function of the initial motion vector that is assigned to this at least one additional image block.

Abstract: A time-discrete picture signal is formed from an analog picture signal, such as a luminance signal or a chrominance signal. Corresponding to the time-discrete picture signal, a time-discrete filter signal is formed, specifically a so-called “peaking signal,” which has a sequence of peaking signal values, of which one value each is associated with one signal value of the time-discrete picture signal. The discrete peaking signal is formed by a digital peaking filter from the discrete picture signal or by an analog peaking filter from the analog picture signal during subsequent sampling of the analog peaking signal. The peaking filter increases the amplitude of selected frequency components of the picture signal.

Abstract: A device for processing a first video signal and a second video signal that contain image data which overlap within a combined picture includes a processing element and a controller. The processing element receives the first video signal containing first image pixel data and receives the second video signal containing second image pixel data, and processes the first video signal and the second video signal to generate a third video signal indicative of an overlap region of images formed by the first and second video signals.

Abstract: The invention relates to a method for rendering an image sequence. wherein an individual image is rendered by rendering monochromatic subimages in temporal succession. A subimage sequence obtained by temporal sequencing of the subimages is generated in motion-compensated fashion.

Abstract: A method for encoding first and second data words, which may represent differential data values (e.g., luminance and chrominance difference data values), onto an encoded data word includes determining a first approximation value, to which a first code word is assigned, for a first data value, and determining a second approximation value, to which a second code word is assigned, for a second data value; mapping the first and second code words onto first and second data segments, respectively, of the encoded data word; determining a first difference value between the first data value and the first approximation value and determining a second difference value between the second data value and the second approximation value; and at least partial mapping of a first difference data word representing the first difference value and/or a second difference data word representing the second difference value onto at least one additional data segment of the encoded data word.

Abstract: The present invention relates to methods of detecting neurodegenerative diseases or disorders, particularly to methods for early detection of neurodegenerative diseases, such as Parkinson's disease. The present invention provides a method for detecting a neurodegenerative disease in a subject, the method comprising testing the subject for an indicator of release of neuromelanin from cells in the brain, wherein a positive test is indicative of death of brain cells containing neuromelanin and is characterised by an elevated level of the indicator of release of neuromelanin compared to control values.

Abstract: The invention relates to a method and a device for determining the spacing between a first sequence of signal values and a second sequence of signal values, wherein a third signal value of the second sequence lying temporally or spatially between the first and second signal values is assigned to one first signal value and second signal value each of the first sequence, which values follow each other in succession, wherein the method comprises the determination of at least one first spacing value based on the following method steps: a) determining a mixing value from the first and second signal values by weighting these signal values; b) determining a mathematical spacing between the mixing value and the third signal value in order to provide a second spacing value; c) determining an interval width value which is dependent on the interval width of an interval defined by the first and second signal values; d) mapping the first spacing value onto the second spacing value using the interval width value as the map

Abstract: Method for motion-vector-aided interpolation of a pixel of an intermediate image lying between two input images includes a first pixel being selected from a first field and a second pixel being selected from a second field using a first motion vector, and a third pixel being selected from the first field and a fourth pixel being selected from the second field using a second motion vector. Next, an interval specified by video information values of the first pixel and the second pixel or an interval specified by video information values of the third pixel and the fourth pixel is determined and the video information values are mixed such that the video information value of the pixel to be interpolated lies within this interval.

Abstract: An improved device for controlled illumination of a cavity such as in endoscopy or inspection of machinery within a housing; the device comprises a light source and a fiber optics for feeding light into the cavity, and a control means arranged between the light source and the entrance plane of the fiber optics for controlling the luminous density at the exit plane of the fiber optics; the control means is in the form of a diaphragm disc arranged between the light source and the entrance plane of the fiber optics and is capable of linear or rotational displacement or motion; the disc has an opening having a width that varies cross-wise to the direction of displacement or motion of the disc-shaped diaphragm so as to provide a variable aperture; the luminous density at the exit plane will, in general, be determined by the light flux that impinges upon the entry plane, and that flux is controlled by the variable aperture.
