摘要： A system and method that determines the strength of an edge in a video image using a gradient of the edge in a first direction and a gradient of the edge in a second direction. The system uses the gradient in the first direction and the gradient in the second direction to approximate a distance function to determine the strength of the edge. A programmable threshold may be used in the determination, where an edge is treated like it does not exist if the distance is less than the threshold. The distance function may be an approximation of the Cartesian distance function.

摘要： A system and method that produces a spatial average for interlaced video in a deinterlacer. The system detects edges in the video images and determines the angle at which the edges are oriented based on the gradient in the x-direction and the gradient in the y-direction. The direction of the edge is determined using the angle information of the edge. The system may also determine the strength of the edge. Based on the determined characteristics of the edge a filter may be selected to produce a spatial average of the edge in the image.

摘要： A method and system automatically harmonizes access to a given software application program via different access devices. Through use of the method and system, a financial institution can provide access to a given application (such as, for example, automatic bill payment services) to customers using different access devices such web browsers, screen phones and personal computers. A single application program is all that needs to be written and maintained by the financial institution. Also, the method and system enables financial institutions to “leverage” existing programs because now the institution can automatically “project” its existing stock of program services unto new access devices—devices which may not have even existed at the time the program was created. By receiving information from the user via the user's access device, including information identifying the type of device being used and the application program the user wishes to access, the present invention solves these problems. The application program is then accessed and the information to be displayed to the user is identified. This information is automatically translated into a format which is compatible with the device, including its display, and sent to the device for display. The user, in turn, inputs information in response to the displayed information and this input information is automatically translated into a format which is compatible with the application program and is sent to the application program. The response generated by the application program is automatically translated to be compatible with the device and is sent to the device.

摘要： Provided is an architecture (hardware implementation) for an authentication engine to increase the speed at which multi-loop and/or multi-round authentication algorithms may be performed on data packets transmitted over a computer network. Authentication engines in accordance with the present invention apply a variety of techniques that may include, in various applications, collapsing two multi-round authentication algorithm (e.g., SHA1 or MD5 or variants) processing rounds into one; reducing operational overhead by scheduling the additions required by a multi-round authentication algorithm in such a matter as to reduce the overall critical timing path (“hiding the ads”); and, for a multi-loop (e.g., HMAC) variant of a multi-round authentication algorithm, pipelining the inner and outer loops. In one particular example of applying the invention in an authentication engine using the HMAC-SHA1 algorithm of the IPSec protocol, collapsing of the conventional 80 SHA1 rounds into 40 rounds, hiding the ads, and pipelining the inner and outer loops allows HMAC-SHAl to be conducted in approximately the same time as conventional SHA1.

摘要： Processing video signals may comprise converting interlaced formatted video to progressive scan video by simultaneously performing: color edge detection on a first and second field; temporal filtering on the second field and third field; and 3:2 pull down detecting on the second field and the third field. A bound output may be generated by binding an output from the color edge detecting and are output from the temporal filtering.
