摘要： An apparatus and method that provide consistent output across a plurality of different hard copy output devices which may be included in a system comprising an image data source and a hard copy output device. The image data source supplies image data to a printable image data adjusting apparatus. The image data supplied may be in a device-dependent color space or a device-independent color space. If the image data is in a device-dependent color space, the printable image data adjusting apparatus first converts the image data into device-independent image data and stores it in memory as target image data. If the image data is already device-independent image data, the image data are simply stored in the memory of the printable image data adjusting apparatus as target image data. The printable image data adjusting apparatus then uses the target image data to generate printable image data. The hard copy output device uses the printable image data to generate a hard copy image. The hard copy image is then passed within the optical field of a sensor that detects device-independent image data values of the hard copy image. The detected device-independent image data values are then compared against the target image data to generate color adjustment factors. The color adjustment factors are then used to produce a hard copy image having detected device-independent image data values that more closely represent the target image data. The apparatus and method may be implemented in real-time with or without human intervention.

摘要： A mapping system for converting an input signal value to an output value wherein certain outputs are predetermined to be critical. An engine for converting input values to output values is associated with an input value transforming system wherein certain input values corresponding to the critical output values are transformed prior to input to the engine for adjusting the input value so that the engine generates a particularly desired output. The transforming comprises selecting a set of basis functions for effecting a warping of input values near the input value corresponding to the critical output value. The basis functions determine the extent and gradient of input value adjustment for nearby values to the critical value. The basis functions are included within an objective function defining the purpose of the system and the functions are solved to generate the desired adjusted input value. The system has particular applicability to color gamut mapping in a print system wherein output color needs to be accurately printed and colors nearby the critical color can be generated with minimal image artifacts.

摘要： A method for determining a parking violation includes receiving video data as a sequence of frames provided by a camera. The method includes defining a location of an exclusion zone in the video data. The method includes detecting a vehicle located in the defined exclusion zone. The detecting includes determining a background in an initial frame of the video data and determining a background in a select frame by applying a predetermined updating process. The detecting includes subtracting the background of the select frame from the initial frame to obtain an image difference. The detecting includes classifying the pixels in the image difference as foreground or background pixels and classifying the pixels in the foreground image as vehicle or non-vehicle pixels. The method includes determining a duration that the detected vehicle is in the exclusion zone based on a number of the sequence of frames including the detected vehicle.

摘要： What is disclosed is a novel system and method of inheriting intended GCR into a 4-to-4 cascaded LUT to compensate for print engine change which adversely impacts the quality of an output print. The present method uses the device link transform to generate starting LUT nodes for the inverse of the drifted printer model by inputting CMYK or RGB into the device link at a color space resolution sufficient to determine output nodes. Lab and CMYK values are derived from this process, and a “starting LUT” is created at the Lab destination nodes. An iterative control begins with this starting LUT to produce an inverse drifted printer model that contains a close approximation for the intended GCR. The present method captures the intent of the device link transform for a fleet and generates the cascaded LUT for drift, specific printer, side1/side2, and other modes leading to special GCRs.

摘要： What is disclosed is a system and method for post-processing a multi-spectral image which has already been processed for pixel classification. A binary image is received which contains pixels that have been classified using a pixel classification method. Each pixel in the image has an associated intensity value and has a pixel value of 1 or 0 depending on whether the pixel has been classified as a material of interest or not. A block of size m×n is defined. Pixel values in a block are changed according to a threshold-based filtering criteria such that pixels in the same block all have the same binary value. The block is then shifted by k pixels and pixel processing repeats until all pixels have been processed. Once all blocks have been processed, contiguous pixels having the same binary value are grouped to form objects. In such a manner, pixel classification errors are reduced.

摘要： What is disclosed is a system and method which addresses the problem of inheriting color management intent from a fleet color management LUT into a 4-to-4 cascaded LUT. The LUT is updated starting with a set of patches that either form a uniform or non-uniform grid of the LUT or can be projected to a uniform or non-uniform grid in the CMYK space using, e.g., PCA. A set of L*a*b* target as well a variable that serve the purpose of preserving the GCR and other elements of the fleet profile is obtained by passing the set of CMYK values to the fleet printer model. By iterating on the printer (or the printer model of the engine at the moment of the engine change) and converging to the targets, the engine device cmyk set is obtained. The LUT is formed between the uniform or non-uniform gridded CMYK and the device cmyk.
