Abstract: Methods and systems for image processing are provided. A method for processing images of a scene includes receiving image data of a reference and a current frame; generating N motion vectors that describe motion of the image data within the scene by computing a correlation function on the reference and current frames at each of N registration points; registering the current frame based on the N motion vectors to produce a registered current frame; and updating the image data of the scene based on the registered current frame. Optionally, registered frames may be oversampled. Techniques for generating the N motion vectors according to roll, zoom, shift and optical flow calculations, updating image data of the scene according to switched and intermediate integration approaches, re-introducing smoothed motion into image data of the scene, re-initializing the process, and processing images of a scene and moving target within the scene are provided.

Abstract: The aggregation of platelets on the surface of a foreign body exposed to the flowing blood of a living being (such as plastic tubing, a balloon or the end of a catheter surgically inserted in a blood vessel, a stent implanted therein or synthetic grafts, which surface normal promotes such platelet aggregation to form a coating firmly affixed to that surface which would restrict the flow of blood past that surface or to form a blood clot detachable from that surface), is inhibited by a gas permeable coating on the surface of a physiologically acceptable polymer as which contains dissolved or dispersed therein a nitrosyl-containing organometallic compound, such as sodium nitroprusside, which is protected from diffusion from the coating and from direct contact with the blood and which slowly decomposes at the body temperature within the coating and in so doing releases a platelet aggregation-inhibiting amount of nitric oxide which diffuses from the coating during the period when platelet aggregation by the surfa

Abstract: A surface of a foreign body exposed to the flowing blood of a living being which normally would promote the aggregation of platelets in that blood to form a layer affixed to that surface and thus restrict the flow of blood past that surface or to form a blood clot detachable from that surface which when detached could trigger a stroke, heart attack or partial loss of organ function, such as plastic tubing, a balloon or the end of a catheter surgically inserted in a blood vessel or a stent implanted therein, e.g.
