  • Publication number: 20150039532
    Abstract: An improved volatility index and related futures contracts are provided. An index in accordance with the principals of the present invention estimates expected volatility from the prices of stock index options in a wide range of strike prices, not just at-the-money strikes. Also, an index in accordance with the principals of the present invention is not calculated from the Black/Scholes or any other option pricing model: the index of the present invention uses a newly developed formula to derive expected volatility by averaging the weighted prices of out-of-the money put and call options. In accordance with another aspect of the present invention, derivative contracts such as futures and options based on the volatility index of the present invention are provided.

  • Patent number: 7889512
    Abstract: A technique for observing signaling on the traces between ICs on a PC board without introducing significant signal degradation is provided. A route-through connector footprint allows the use of a standard connector without the use of stub traces. The route-through connector footprint allows a standard connector to be introduced directly into the line traces routed between ICs. Because stub traces are not used, this technique for mechanical interconnection into the line traces on a PC board allows for a single board layout to be used for both test and production. Additionally, because stub traces are not used, signal quality is minimally impacted and testing can be performed at operational speeds improving the reliability of the test function. The use of a route-through connector footprint additionally saves PC board space and cost.

  • Publication number: 20070103707
    Abstract: Colors similar to those which would be used in calibrating a target printer are printed on a printer of the same model and with the same materials set as anticipated for the printer calibration. These all lie within a substantially reduced portion of the gamuts of both the printer and scanner. A scanner characterization is derived only for those portions of color space corresponding to the printed colors. This may be done using spline fitting in one or more dimensions. While generic scanner calibrations generally have errors in excess of ?E=7, with these techniques values generally less than 1.7 were obtained. This is sufficient for printer calibration.

  • Publication number: 20070103743
    Abstract: In one form, the method comprises obtaining scanned values of the image, scaling the scanned values to obtain scaled values, applying a non-linear correction function to the scaled values to obtain a first approximation of corrected reflectance values, filtering the corrected reflectance values by applying a piecewise Gaussian filter, applying the non-linear correction function to obtain a successive approximation of the corrected reflectance values, determining whether the successive approximation of the crrected reflectance values are sufficiently converged, selectively repeating the filtering and applying if the corrected reflectance values are insuffciently converged and selecting the corrected reflectance values for subsequent processing if the corrected reflectance values are sufficiently converged.

  • Publication number: 20070002344
    Abstract: A calibration or characterization system is provided wherein the number of repeated patches or the size of a patch of a given color is printed to be approximately proportional to the square of the expected noise level. In that way, when multiple measurements for a given patch are averaged, all patch averages have approximately the same reliability.

  • Publication number: 20060227148
    Abstract: Provided herein are teachings directed to calibrating an output device such as a color display, using a visual method of determining the gamma for the blue primary that is easier to perform and more consistent than methodologies employing a luminance-matching task. The methodology is based on the insight that accurate gamma estimation for blue is important not for luminance reproduction, but for proper color-balance, and most importantly grey-balance. Thus, it follows to use grey-balancing, rather than luminance-matching, as the criterion for selecting the blue gamma value. One variant as taught herein is to provide a user visual task to find a patch best representing neutral, given previously determined calibrated digital values for the red and green primaries that produce 50% fractional luminance. A large patch is displayed within a larger surround containing both a white border and either a checkerboard or a line pattern, so as to establish a reference for the neutral axis.

  • Publication number: 20060109514
    Abstract: In an image-on-image (IOI) color processing system, which superimposes toner images of different color separation toners onto a photoreceptor, a method for determining composite toner coverage on a page includes determining the order in which the color separations will be printed; determining an attenuation factor for each individual color separation and for all combinations of the color separations; determining a fractional amount of toner that is requested for each separation; and summing the fractional amounts of toner requested for each separation times the fraction of the substrate that is not yet covered by prior separations, and the amounts of toner that are deposited on each of the prior separations times the attenuation factor corresponding to that combination of prior separations, in all combinations. These revised coverages can be used to adjust the input values of an image before it is used in a reload detection method.

  • Publication number: 20060109499
    Abstract: An image rendering system includes a digital front end to electronically analyze image data to generate geometry dependent image content information. A print engine, operatively connected to the digital front end, renders the image data. A print engine controller, operatively connected to the digital front end and the print engine, controls various parameters of the print engine. The digital front end transmits the image content information to the print engine controller. The print engine controller adjusts a parameter of the print engine based on the transmitted image content information. The transmitted image content information may be coverage information, reload information, and/or toner pile height information. The parameter of the print engine adjusted based upon the transmitted image content information may be fuser temperature and/or process speed of a developer housing and/or flow rate of toner into a developer housing.

  • Publication number: 20060110009
    Abstract: Systems and methods for detecting image quality defects in images rendered by a rendering device. Original image data is rendered by an image rendering device, and the rendered image is captured by an image capturing device. Regions of interest may be identified to provide information indicating where image quality defects of the rendering device, may be identified. At each region of interest, the original image data may be compared to the captured image data of a corresponding region of interest to determine color difference of the captured image at the region of interest. The color difference may be subsequently converted from a device independent color space to a device dependent color space. Based on the converted color difference and input intensity of the original image data at the region of interest, a colorant error may be determined for the region of interest, and/or a scan line and a row line including the region of interest.

  • Publication number: 20060109487
    Abstract: A method for determining if an image to be printed is subject to reload artifact, includes providing an image (which may be a low resolution version of the image) to be printed; locating within the image a first area to be printed requiring toner of sufficient quantity to cause reload of the donor roll; locating within the image a second area substantially one rotation of the donor roll subsequent to the first area; determining if the second region is a region of high area toner coverage, wherein high area toner coverage comprises toner coverage exceeding a predetermined threshold value; if the second region is a region of high area toner coverage, determining if the second region contains high frequency content; if the second region contains high frequency content, the second region is not subject to reload artifact; else the second region is subject to reload artifact.

  • Publication number: 20060103861
    Abstract: Systems and methods preserve the information lost in gamut-mapping during marking (e.g., printing) such that the lost information survives the marking and recapture (e.g. scanning) process. Generally, an encoding method may include gamut-mapping and image for a particular device; determining a residual image; and embedding the information needed to recover the residual image within the pixels of the gamut-mapped image. Generally, a decoding method may include extracting the embedded information from the image; and using the residual image to restore the gamut-mapped image to the original image.

  • Publication number: 20060038828
    Abstract: Color error associated with an image rendered by a rendering device is calculated in the no more than N?1 dimensions of an associated color sensor color space. The color error is assumed to be small. A differential of a mapping from an N dimensional rendering device color space to the associated color sensor color space is used to calculate a colorant error in the N dimensions of the rendering device color space. Where necessary, appropriate assumptions are used to constrain an underdetermined system of equations. Where calculated colorant error is unreasonable, the calculated colorant error is clipped and colorant error is recalculated based on the clipped value.
