A symmetric discrete-time square-root-raised-cosine filter may be utilized to process a serial input signal and to produce an output square in each clock cycle. The filter may be adapted to decrease the computational complexity of the resulting calculations, making the filter amenable to use in power sensitive applications and in those situations where the available processor's performance is relatively limited.

Disclosed is a method and apparatus to provide for fingerprint minutiae matching using scoring techniques. A plurality of minutiae in a fingerprint image is defined. A score associated with each minutia corresponding to the validity of each minutia is estimated. The fingerprint image is then matched against one or more sample fingerprint images utilizing a partial point set pattern matching (PSPM) algorithm.

Fingerprint minutiae matching using scoring techniques

In one embodiment, the present invention includes a method to use active contours to detect image boundaries of a first view and a second view of a human face, and mark a first set of fiducial points on the first view and a second set of fiducial points on the second view. Using the fiducial points, feature vectors may be calculated and stored in a database for later comparison with a query image.

A sensor for color and depth information capture is disclosed. A filter passes selected wavelengths according to a predetermined pattern to the sensor. The sensor measures light intensities passed by the filter. In one embodiment, the wavelengths passed by the filter correspond to red, green, blue and infrared light. The intensity values can be used for interpolation operations to provide intensity values for areas not captured by the sensor. For example, in an area corresponding to a pixel for which an intensity of red light is captured, interpolation operations using neighboring intensity values can be used to provide an estimation of blue, green and infrared intensities. Red, green and blue intensity values, whether captured or interpolated, are used to provide visible color image information. Infrared intensity values, whether captured or interpolated, are used to provide depth and/or surface texture information.

A method, apparatus,and system for performing motion estimation using a logarithmic search are described. One or more image signal processing engines including a plurality of processing elements are employed. The one or more image signal processing engines are mutually coupled by a register file switch, and the one or more image signal processing engines perform a block matching calculation that includes a sum of absolute differences. The plurality of processing elements is further mutually coupled such that, during the block matching calculation, parallel processing and pixel data sharing of reference block pixel locations is employed by the plurality of processing elements.

A dual mode filter for mobile communication may implement two disparate cellular systems such as GSM and W-CDMA. The same transceiver may be utilized to selectively receive and transmit in either of the two systems. When the system is in a GSM area, the system sends and receives GSM signals using programmable filters. Two cascaded digital decimation filters may substitute for one narrow band digital decimation filter in conventional designs. One of the filters is a multi-band digital decimation filter with N bands and the other of the digital filters is used to reject the N&#x2212;1 multi-band of the system. The number of taps on each filter may selectively be set to implement either GSM or W-CDMA. In addition, the output for the system may be set to be the output of the first filter, in the case of a W-CDMA system, or the combination of the two cascaded filters in a GSM system.

In one embodiment, the present invention includes a method to obtain a query image and search a database corresponding to object images for a solution set having a maximum similarity to the query image using fuzzy logic. Also in certain embodiments, based on fuzzy logic, the database may be partitioned into multiple sets based on a fuzzy similarity analysis of a measure of the object images to various thresholds.

A method of converting from a sub-sampled color image in a first color space format to a full color image in a second color space format includes the following. A sub-sampled color image in a first color space format is transformed to a second color space format. At least one color plane of the transformed image is upscaled, the one color plane corresponding to one of the color space dimensions of the second color space format, to provide the full color image in the second color space format. Of course, many other embodiments other than the preceding embodiment are also within the scope of the present invention.

Embodiments of a color image matching scheme are disclosed. In one embodiment, a pixel intensity count is determined for color components of color images in a database and for a query color image. A fuzzy similarity and/or a fuzzy dissimilarity between the query image and the database images is computed based at least in part on the pixel intensities counts. An image is selected from the database based at least in part on the computed fuzzy similarity and/or dissimilarity, where computing a fuzzy similarity and/or dissimilarity includes computing the matching intensity. Other embodiments are described and claimed.
