A processing and user interface system supports Internet application and web page navigation for sequential task oriented processes, workflow management and user specific, customizable, interactive and other organizable processes. A network (Internet, Intranet or other network) compatible user interface system supports a process including a sequence of subtasks. The system initiates display of a composite window representing a plurality of overlaid tabbed web page (or application) windows each including a visible tab incorporating an identifier identifying a function provided by a web page or application window associated with a particular subtask of the sequence of subtasks. The visible tabs and corresponding overlaid tabbed windows are sequentially ordered in accordance with the sequence of subtasks. The system initiates display of a subtask web page or application window in the foreground of the composite window in response to user selection of a visible tab corresponding to the subtask web page or application window.

A system for monitoring eyes of an individual includes a human interface for obtaining images of the individual and for providing feedback to the individual and a processor for analyzing the images. The processor transforms an image sequence into a one dimensional signal by extracting relevant features from the images. Analysis of the signal generated then occurs to detect sleepiness. Transformation of the image sequence includes eye localization, eye tracking and eye motion signal generation. The system takes advantage of the relatively high horizontal-contrast density of the eye region to determine eye positions in a greyscale image of a human face.

A method for automatically editing a plurality of CT image slices to provide a three dimensional view of a selected object located within a patient's body comprises providing at least one slab of CT image slices produced by CT scanning system and computing a top MIP image of the slab. An undesirable object is automatically removed from the top MIP image by first detecting all the pixels having illuminating intensity values which represent the undesirable object. Then all the pixels of the object to be removed are set to a substantially zero illuminating intensity value in order to remove the object from the top MIP image of the slab. After the undesirable object is removed from the top MIP image, the edits made thereto are applied to each CT image slice in the slab. The present invention also includes apparatus for performing a 3D reconstruction of CT angiographic images to visualize a selected object located within a patient's body. The apparatus comprises an x-ray tube for projecting energy into a layer of interest in the patient's body and a detector for detecting changes in the projected energy as it exits the layer of interest. The changes detected in the projected energy are indicative of various objects including the selected object that are located within the layer of interest of the patient's body. Moreover, the x-ray tube and detector operate in conjunction to provide at least one slab of CT image slices.

The present invention apparatus and method uses a recursive filter to estimate the instantaneous intensity and temporal rate of change in intensity for object points in consecutive images of an image-sequence. The estimates of the intensity and its temporal rate of change are updated for each new image in the image sequence. The amount of smoothing introduced by the recursive filter is dependant upon the estimates computed for the intensity and temporal rate of change. As such, the recursive filter corrects the image sequence in accordance with each new set of estimates. Since motion in an image-sequence is implicit in the rate of change of intensity, the recursive filter is able to achieve motion compensated enhancements.
