Abstract: An image sensor comprising an integrated circuit chip that includes both a pixel array and edge detection circuitry hardwired together on the chip. The pixel array provides an addressable, non-destructive readout of the pixel data, with the edge detection circuit providing a hardwired implementation of a pair of n×n masks that are convolved with the pixel array data to thereby generate horizontal and vertical edge data that is combined together and outputted by the image sensor. The masks are implemented as a pair of one-dimensional filters, with one of the filters being a one-dimensional Gaussian filter used to smooth the pixel data along one axis and the other filter providing a first derivative Gaussian function to detect edges along the other, orthogonal axis.

Abstract: A method for concept word management. The method comprises receiving an editing request for a text document from a requestor. The editing request includes an initial phrase located in the text document. An ontology associated with the text document is searched for the initial phrase. The initial phrase is distinguished in the text document in response to the initial phrase being located in the ontology and to the editing request further including a distinguish phrase command. An alternate phrase associated with the initial phrase is presented to the requestor in response to the initial phrase being located in the ontology and to the editing request further including a display alternate phrase command. The initial phrase is replaced in the text document with the alternate phrase in response to the editing request further including a replace phrase command.
