摘要:
A contexture dependent dynamic range remapping system utilizes background estimation, mask generation, parameter estimation and dynamic range remapping of an original image to provide an optimum output image. The dynamic range remapping includes an additive algorithm or a multiplicative algorithm or a combination of both algorithms. The output from the algorithms could be filtered by an edge-preserving filter to provide a filtered output image. The system adaptively compresses the dynamic range of the DC and slow-varying signals in the original image significantly while preserving and enhancing fine structures.

The present invention discloses a method for the catalytic reduction of sulfur dioxide, for example in flue gas, by carbon monoxide using lanthanum oxysulfide as the active catalyst. The catalyst is prepared from lanthanum oxide by hydration and sulfidization, the latter step being carried out in the gas stream itself. This method of preparation has more general applicability and can also be used as a method for the preparation of lanthanum, yttrium, gadolinium and lutetium oxysulfides generally.

A detection system identifies a person by rapidly analyzing an image frame from a video camera for the presence of a face by reducing the image in resolution and normalizing the image to compensate for lighting changes and compares the normalized image with a background image to produce a binary interest mask. The most likely position of a face is then determined by identifying a top, bottom and sides of a possible head region to define a bounding box, normalizing the pixel data within the bounding box to further compensate for lighting variations, and resizing the box to match identification templates stored in memory. The best match from the identification templates is provided with a score indicative of the degree of the match. If the score does not exceed a first score threshold, then no face is assumed present. If the score exceeds a first and second score threshold, then a face is assumed present. If the first score threshold is exceeded but the second is not, a further eye location procedure is performed on the data to determine if a face is present.

An apparatus for examining tissue in vivo by means of the optical properties of the tissue generates a measuring chirp signal which is introduced into a tissue-containing subject as a coherent optical chirp signal. The parts of the measuring chirp signal emerging from the subject are superimposed with a reference chirp signal to form a superposition signal that is supplied to a filter that only allows those parts of the superposition signal to pass that represent those parts of the measuring chirp signal emerging from the subject which have traversed a defined, optical path length within the subject.

A method of manufacturing microstructures, such as MEMS or NEMS devices, including forming a protective layer on a surface of a moveable component of the microstructure. For example, a silicide layer may be formed on one or more surfaces of a poly-silicon mass that is moveable with respect to a substrate of the microstructure. The process may be self-aligning.

A method includes forming a recess in a first surface of a substrate, the recess having a width, depth, and height selected to correspond to a width, depth, and height of a fluid chamber, forming a sacrificial material in the recess, forming a first heater element, forming a metal layer overlying the first heater element, and forming a nozzle opening in the metal layer to expose the sacrificial material. The method also includes forming a path from a second surface of the substrate to expose the sacrificial material and removing the sacrificial material from the recess to expose the chamber with the selected width, depth, and height, the chamber in fluid communication with the path, the nozzle opening, and a surrounding environment.

A thin film power transistor includes a plurality of first doped regions over a substrate and a second doped region forming a body. At least a portion of the body is disposed between the plurality of first doped regions. The thin film power transistor also includes a gate over the substrate. The thin film power transistor further includes a dielectric layer, at least a portion of which is disposed between (i) the gate and (ii) the first and second doped regions. In addition, the thin film power transistor includes a plurality of contacts contacting the plurality of first doped regions, where the plurality of first doped regions forms a source and a drain of the thin film power transistor. The first doped regions could represent n-type regions (such as N− regions), and the second doped region could represent a p-type region (such as a P− region). The first doped regions could also represent p-type regions, and the second doped region could represent an n-type region.
