摘要： The invention is related to non-volatile storage devices.The invention proposes a non-volatile storage device comprising a storage unit, means for receiving an access change indication and means for changing access to said storage unit in response to said access change indication wherein access prior to reception of said access change indication is such that data can be stored in said storage unit and already stored data can be altered and access after said access change is such that at least some of the already stored data is unalterable but still can be read wherein access to said at least some of the already stored data is irreversible after access change in response to receiving said access change indication.This combines the advantages of permanent, forgery-proof storage with the advantages of erasable storage.

摘要： Wavelet thresholding using discrete wavelet transforms is a sophisticated and effective approach for noise reduction. However, usage of integer arithmetic implies that not the full range of input values can be used. A method for selectively reducing noise in a digital signal having a first range of values comprises steps of decomposing the digital signal to a plurality of frequency sub-bands, wherein before, during or after the decomposing the digital signal or at least one sub-band is expanded by one or more bits to a second range of integer values, removing in at least one of the frequency sub-bands values that are below a threshold, re-combining the frequency sub-bands, after removing said values that are below a threshold, into an expanded output signal, and de-expanding the expanded output signal, wherein a signal having the first range of values is obtained.

摘要： A method and an apparatus for recovering a component of a distortion field of an image of a set of multi-view images are described. Also described are a method and an apparatus for determining a disparity field of an image of a set of multi-view images, which makes use of such method.In a first step pixel correspondences between the image and another image of the set of multi-view images are determined. A disparity field is then determined from at least a subset of the determined pixel correspondences. The disparity field is smoothed and the component of the distortion field is estimated from the smoothed disparity field. When determining a second disparity field the estimated component of the distortion field is taken into account when determining pixel correspondences between the image and another image of the set of multi-view images.

摘要： A method and an apparatus for determining a confidence value of a disparity estimate for a pixel or a group of pixels of a selected image of at least two stereo images are described, the confidence value being a measure for an improved reliability value of the disparity estimate for the pixel or the group of pixels. First an initial reliability value of the disparity estimate for the pixel or the group of pixels is determined, wherein the reliability is one of at least reliable and unreliable. Then a distance of the pixel or the group of pixels to a nearest pixel or group of pixels with an unreliable disparity estimate is determined. Finally, the confidence value of the disparity estimate for the pixel or the group of pixels is obtained from the determined distance.

摘要： For NAND flash devices, two specific bounds for the program time are defined in the data sheets: a typical program time, during which more than 50% of all pages are programmed, and a maximum program time. Reduction of the maximum program time to an effective program time is possible using the following method for writing to a flash memory, comprising the steps of specifying an effective program time that is between typical and maximum program time, writing first data to the flash memory, after the effective program time checking if the programming cycle is finished, if it is finished writing second data to the flash memory, and if it is not finished writing the at least second data to a buffer memory and marking them as not to be overwritten, repeating the previous steps as long as further data are to be stored, determining a free location in a flash memory, and copying the at least second data from the buffer memory to the determined location in the flash memory.
