Abstract: Presented herein is a method and system for reducing memory requirements in audio signal processing by de-interleaving audio information with at least two static buffers and a dynamic buffer. The method may include writing interleaved audio information to a first static memory device. The method may also include de-interleaving the audio information and writing de-interleaved audio information to a second static memory device. The method may also include writing de-interleaved audio information to a dynamic memory device from the second static memory device and overwriting interleaved audio information with new interleaved audio information in the first static memory device. The method may also include overwriting interleaved audio information in the first static memory device with de-interleaved audio information from the dynamic memory device and decoding the audio information.

Abstract: A system for efficiently converting computer graphics images to film images with accurate color management is described. The system involves the creation of a direct mapping of chromaticity and intensity data from the values used to generate images on a computer monitor to the values used to display the images on projected motion picture film.

Abstract: A method and system for preventing routing maelstrom loops of automatically routed electronic mail which is operational with intelligent agents and computer-processor hardware components, and includes a software based solution comprising a processor readable code of instructions. The code of instructions generally comprise a routine for tagging processed e-mail message with a system generated special identifying tag revealing each source subscriber, a routine for ascertaining whether a received message intended for automatic routing contains any special tag and a corresponding routine for deciding whether any of the special tags contain the current source subscriber's identification before exercising any routing rules against the message. If the subscriber's ID is listed in the particular e-mail being routed, then the system of the invention determines that a complete loop has been made and terminates further transmission since the next target subscriber has already received the message.

Abstract: A template useful in registering an incoming bitmapped image with a master bitmapped image is created by convolving the master with a Gaussian function and computing the gradient of the resulting scalar field. According to the invention, the incoming image is iteratively moved with respect to the template in response to the gradient of the scalar field formed by the convolution operation, i.e., the direction of adjustment is a function of the gradient of the scalar field formed by the convolution operation used to create the template. According to one embodiment of the invention, the registration process is terminated when the error between the master and the image is below a predefined threshold.

Abstract: Character recognition method and system that identifies an input character as being a unique member of a defined character set. Specifically, a character bit-map of an input character is first generated. Thereafter, a character recognition procedure processes the character bit-map to generate a set of confidence measures one for each of the members of the character set. The confidence measures represent the degree of confidence that the input character corresponds to the members of the character set. A test is then made to determine if the confidence measure with the highest degree of confidence is acceptable. If there is an acceptable confidence measure, the member of the character set with the acceptable confidence measure is reported as the output character. If there is no acceptable confidence measure, a number of characters with the highest confidence measures are identified as candidates.

Abstract: A method and apparatus for segmenting a bitmapped image (200). In general, the bitmap image is modeled as a parallel plate capacitor. In so doing, opposing boundaries (302, 304) of the bitmap image are each assigned a voltage value and each pixel (300, 301) within the bitmap image is assigned a charge value. Generally, a positive charge is assigned to the pixels which comprise a pattern in the bitmap image and the remainder of the pixels are assigned a zero charge. A potential distribution field (400) which results from the interaction of the boundary voltages with the pattern of charges is determined by numerically solving a two-dimensional Poison's equation. Each contiguous path (306) of steepest potential gradient from one boundary (304) to opposing boundary (302) forms a demarcation line along which the image is segmented. Each resulting segmented image (500) is stored as an individual file for subsequent processing.
