Abstract: A local adaptive method is proposed for automatic detection of microaneurysms in a digital ocular fundus image. Multiple subregions of the image are automatically analyzed and adapted to local intensity variation and properties. A priori region and location information about structural features such as vessels, optic disk and hard exudates are incorporated to further improve the detection accuracy. The method effectively improves the specificity of microaneurysms detection, without sacrificing sensitivity. The method may be used in automatic level-one grading of diabetic retinopathy screening.

Abstract: A method for optic disk detection in retinal images, includes: extracting a vessel tree from a retinal image; locating an optic disk in the retinal image using the vessel tree; enhancing a contrast of the optic disk; removing vessels from the contrast enhanced optic disk; detecting a boundary of the optic disk with vessels removed by generating an edge map; projecting the edge map at a plurality of angles by using a radon transform; and estimating a radius and center of the optic disk using the projections.

Abstract: This invention is related to remote document access. More specifically, mobile device users are provided with the ability to easily access remote documents over a network such as the Internet, and to quickly view the content without resorting to a local download. By introducing streaming-on-demand and dividing the page into smaller segments, the invention significantly reduces bandwidth usage and speeds up the complete viewing process, since only data corresponding to the active viewing window is transmitted. As a result, resources are effectively utilized, and users seamlessly view documents. Moreover, users are able to easily identify documents by viewing thumbnails of original layouts and/or reading document content with an image quality that is very close to what is on their desktop. Without downloading the complete document onto a mobile device, this invention allows a mobile user to approve or forward the document to coworkers, and to print or fax the document on a nearby printer or fax machine.

Abstract: A multimedia collaboration system combines unique multimedia communications and media processing mechanisms with off-the-shelf components that support information sharing and distribution. More specifically, the system provides an asynchronous multimedia collaboration whiteboard that enables the creation of messages containing synchronized voice, graphics and mouse gestures to describe conditions associated with an underlying multimedia object. On the server side, the system includes a delayed conference manager connected to a conference database, an email server, a newsgroup server and a web server. On the client side, the system includes a dynamic annotation editor which enables the use of synchronized voice, graphics and mouse gestures in the discussion. The client side also includes a newsgroup and email reader and a web browser.
