Abstract: In conducting multiple repetitions of MS/MS analysis on the same test sample for which a precursor ion whose m/z is known (m/z=M) has been established, MS/MS analysis is conducted under a dissociation condition in which CID is less prone to occur in part of the analysis. When an MS/MS spectrum is created by summing up spectral data thus obtained, a known precursor ion is observed at m/z=M without exception. Thus, a peak corresponding to the precursor ion is detected on the MS/MS spectrum, a mass deviation between an actual measured value and theoretical value M of m/z at the peak is determined, and a spectrum is created by correcting other peaks for mass shifts based on the mass deviation. This makes it possible to mass-calibrate the MS/MS spectrum in substantially the same manner as an internal standard method and improve mass accuracy over conventional methods.

Abstract: In a Phase Plane Correlation (PPC) process, using adaptive frequency domain filtering to aid in generating candidate motion vectors. It is determined when it is beneficial to pre-filter an input image, prior to a PPC process. This results in more reliable and consistent PPC surfaces than otherwise. The filter is applied in the frequency domain where time-domain convolution becomes a much more efficient component-wise multiplication with an in-place window. An energy measure of the high-frequency content in the computed Fourier surfaces gauges the degree of high frequency content in the image. First, the Fourier transform of the two images is computed. Then, the high-frequency content is estimated from the Fourier surfaces. A window function is computed as a function of the high-frequency energy. The window is applied to the Fourier surfaces. Then, the modified Fourier surfaces are fed into the PPC process.

Specifically, a white point of a display may be calibrated using subtractive color measurements rather than merely additive color measurements.

Thus, any crosstalk effect between channels may be accounted for, even though the same crosstalk effect might not be apparent using additive color measurements in which only a single channel color channel were measured.

The method describes a means by which this double indication artifact may be removed by an appropriate processing of RFEC measurements performed by an apparatus specifically designed for this purpose. The invention is particularly well designed for applications in the oilfield industry.
