Abstract: A novel modification to the order statistics filters called the Adaptive Weighted-Local-Difference Order Statistics is shown that will act as a generic framework for the design of adaptive filters suitable for specific signal processing applications. To demonstrate the design of filters using this framework two implementations were defined and evaluated: Edge Orientation Adaptive Weighted-Local-Difference Median Filter (EOAWLDMF) and Luminance-Similarity Adaptive Weighted-Local-Difference Median Filter (LSAWLDMF) for restoration of noisy images.

Abstract: An electronic travel aid (ETA) for visually impaired and blind people (subject) with minimum physical interface adapted to perform real-time navigation without digital camera and complex hardware. Importantly, the electronic travel aid relates to real-time situations with speech messages stored in flash memory for aiding the visually impaired or blind people. The electronic travel aid is provided involving wireless or wired technology and is directed to serve as a low-cost, robust, reliable, and user-friendly solution for blind or visually impaired navigation.

Abstract: Method and apparatus for enhancing representations of micro-calcifications in a digital mammogram image. The method includes smoothing the digital mammogram image using a fuzzy smoothing technique to yield a fuzzy smoothed image. The method includes subtracting the fuzzy smoothed image from the digital mammogram image to yield a micro-calcifications enhanced image. The method includes scaling gray level values of pixels in the micro-calcifications enhanced image by a predetermined amount to provide a digital mammogram image with enhanced representations of the micro-calcifications. Apparatus for enhancing representations of micro-calcifications includes an image processing unit that uses an image acquisition unit to receive an image and a digital signal processor to process the image to provide a digital mammogram image with enhanced representations of micro-calcifications.

Abstract: A digital microscope comprises a housing with an image acquisition, an image processing, and a network communication (APC) module. The APC module can further comprise an image capture unit, coupled to an image sensor with a view to a subject on a slide, the image capture unit receiving an image of the subject. The APC module also comprises an image processing unit, coupled to the image capture unit, the image processing unit enhancing the image with classifications. Also, a network interface of the APC module, coupled to the image processing unit and to a network, the network interface sending the enhanced image across to the network and to receive control commands, the control commands associated with the view of the subject.
