Abstract: According to one embodiment, a pattern inspection apparatus includes a first inspection data creation section, a first delay section, a first recognition section, a first extraction section, a first and a second level difference calculation section, a first and a second determination section, and a first logic OR calculation section. The first extraction section extracts data of a sub-resolution pattern from the first inspection data and the first delay data. The first and second level difference calculation section calculate differences between an average output level of a surrounding region for a target pixel of the extracted data from the first inspection data or the first delay data and an output level of the extracted data. The first and second determination sections determine presence or absence of a defect. The first logic OR calculation section calculates logic OR of determination results of the first and second determination sections.

Abstract: A method and system for image suppression and digital-to-analog conversion (DAC) of a radio frequency (RF) signal is disclosed. In one embodiment, a digital input signal having undesired image spectra is input to two paths. In one path, the digital input signal is phase shifted so that an output of each path are out of phase by substantially 180 degrees at a frequency of the undesired image spectra, so that the undesired image spectra are substantially suppressed.

Abstract: An erosion image is generated from an original digital image utilizing a processing image (b) and a target image (T), where each pixel in the target image is processed in parallel. The process entails, for each target pixel, i) determining coordinate values for the target pixel, ii) determining a surrounding pixel area for the target pixel, iii) and processing each pixel in the surrounding pixel area to determine whether or not to updated the value of the target pixel. In processing each surrounding pixel, a determination is made whether the pixel has a value of 1. If not, then the next surrounding pixel is processed. If so, then a determination is made which pixel element of a structuring element overlays the target pixel, and whether that SE pixel has a value of 1. If so, then the value of the target pixel is updated. If not, then the next pixel in the surrounding pixel area is processed. Once the target pixel has been updated a set number of times to a predetermined value (e.g.

Abstract: A method of displaying a time sequence of 2-dimensional data represents each data set in the time sequence as a normalized figure based upon a reference set of data. The perimeter of the normalized figure is color coded to represent deviations from a data standard that corresponds to the 2-dimensional data. For subsequent data sets in the time sequence each normalized figure is sized to form a series of concentric figures for display representing all the data sets in the time sequence so that patterns of both rotational and magnitude changes are visually apparent.

Abstract: Automatic detection and tracking of multiple individuals includes receiving a frame of video and/or audio content and identifying a candidate area for a new face region in the frame. One or more hierarchical verification levels are used to verify whether a human face is in the candidate area, and an indication made that the candidate area includes a face if the one or more hierarchical verification levels verify that a human face is in the candidate area. A plurality of audio and/or video cues are used to track each verified face in the video content from frame to frame.

Abstract: Disclosed is method of controlling an asymmetric waveform generator including the steps of providing a reference timer signal, and generating an asymmetric waveform as a combination of a first sinusoidal wave having a first frequency and a second sinusoidal wave having a second frequency approximately twice the first frequency. The generated asymmetric waveform is sampled to obtain a set of data points, which set of data points is indicative of the generated asymmetric waveform. The method includes analyzing the set of data points in terms of at least a first function relating to an ideal sinusoidal wave of the first frequency, to determine a first set of resultant values relating to the first sinusoidal wave, and analyzing the set of data points in terms of at least a second function relating to an ideal sinusoidal wave of the second frequency, to determine a second set of resultant values relating to the second sinusoidal wave.

Abstract: A method to determine the probability of detection, P(t), of targets within infrared-imaged, pixelated scenes includes dividing the scenes into tar blocks and background blocks. A plurality of .DELTA.T metrics are applied to the blocked scenes to derive various .DELTA.T values for each scene. Factor analysis is then used on the various .DELTA.T values to derive a relative .DELTA.T for each scene. The scenes are divided again, into cells of pixels, in accordance with a plurality of clutter metrics. These clutter metrics are used to derive various clutter values for each scene. Factor analysis is used on the various clutter values to derive relative clutter values for each scene. The relative .DELTA.T values and the relative clutter values are used in determining the probabilities of detection of the targets in the scenes. Based on the probabilities of detection, the optimum scene or set of scenes is selected.

Abstract: A reflective array compressor for a fast pattern recognition system. The system includes a combination of digital and analog processing circuitry which allows the system to achieve super computing processing speeds within an open personal computer architecture. The system receives a bit map which is representative of the unknown pattern, such as a picture of an unknown person. The bit map could have multiple people in it--no other system has "faces in the crowd" ability. The bit map associated with the unknown pattern is then pre-processed and compared against a plurality of known patterns in a database to determine how well the unknown pattern correlates with the known patterns. The reflective array compressor employs concave input and output transducers, and curved reflectors.
