摘要: A method for reducing audio noise in an audio signal acquisition is described herein. The method includes: receiving an input audio signal; separating the input audio signal into a high-frequency portion and a low-frequency portion based on a threshold frequency; synthesizing the low-frequency portion to at least reduce any audio noise therein to generate a new low-frequency portion; combining the high-frequency portion and the new low-frequency portion to form a new audio signal representing the input audio signal; and outputting the new audio signal for the audio signal acquisition.

摘要: Methods, machines, systems and machine-readable instructions for processing an image are described. In one aspect, the image is divided into a population of image blocks. Frequency domain vectors are generated from respective ones of the image blocks. Each of the frequency domain vectors includes a respective set of values corresponding to a set of transform coefficients. Preliminary estimates of quantization parameter values are determined from frequency distributions of the transform coefficient values in a set of the frequency domain vectors corresponding to a variable sample of the population. The variable sample is determined at least in part by at least one threshold. Values of quantization parameters are estimated from the preliminary estimates.

摘要: A method and apparatus for improving the quality of MPEG video are disclosed. In a preferred embodiment, a group of pictures (GOP) is obtained and decompressed, producing an initial decompressed GOP. This initial decompressed GOP is spatially shifted to at least two shift positions. At each shift position, MPEG compression and decompression are applied, producing a resulting decompressed GOP for each shift position. The resulting decompressed GOPs are shifted back to their initial position and combined, preferably by averaging, to form an improved GOP.

摘要: A “path-enhanced” presentation is automatically generated from previously recorded “path-enhanced” multimedia based on time and location information associated with the multimedia. The path based on the time and location information is rendered over a two-dimensional map. The presentation indicates position and progress along the path, and at the same time, previously recorded multimedia corresponding to points or segments of that path are automatically played. When the moving icon reaches a location that is associated with multimedia, that multimedia is automatically played.

摘要: Methods, machines, systems and machine-readable instructions for processing input audio signals are described. In one aspect, an input audio signal has a noise period that includes a targeted noise signal and a noise-free period free of the targeted noise signal. The input audio signal in the noise-free period is divided into spectral time slices each having a respective spectrum. Ones of the spectral time slices of the input audio signal are selected based on the respective spectra of the spectral time slices. An output audio signal is composed for the noise period based at least in part on the selected ones of the spectral time slices of the input audio signal in the noise-free period.

摘要: A calibration apparatus and method for a color printer that allows a user to calibrate a printer without the use of expensive measuring instruments and prior user training is provided. The calibration process prints out two target layouts. On the first target the user selects the primary inks start and end points (highlights and shadows), and the black ink only input value that generates a 30% gray. The primary inks are the device-dependent colorants, cyan, magenta and yellow. The second target compares the 30% black ink with grays made of a combination of cyan, magenta and yellow inks. The user selects the best match in an iterative process. Using this data, calculations are made of the corrections to the original input signal values for the printer. A look up table is updated with corrected input values to compensate for the printer deviation from its standard behavior.
