    Abstract: Methods and apparatus for digital data array edge enhancement are disclosed. A local data window containing a data sample s is selected. Minimum and maximum sample values, max and min, are located within the window, and an edge deflection value ed is defined to have a value between max and min. A diffusion quantity is then calculated to move the value of s towards max, if s is greater than ed, or towards min, if s is smaller than ed. This approach has advantages over gradient-based edge-enhancement, including simplicity, convergence speed, and stability.

    CPC classification number: G06T9/005

    Abstract: A method for compression of compound images. The method determines a classification for a current pixel based upon its causal neighbors and codes the pixel according to a mode determined by the classification. This coding results in production of a symbol for the pixel and the symbol is then mapped to the output stream.

    Abstract: Systems and methods for performing a task via a simple code. Combination of a unique marker and a simple code represents a task. A simple code is submitted manually or by a voice input. Voice recognition and gesture recognition are used. In an aspect, a task is executed when a voice input comprises a predetermined name and a simple code. In another aspect, a task is executed when a voice input comprises a simple code and a user gazes or gestures at a device.

    Abstract: Provided herein are methods and apparatuses for determining a level of cellular metabolic activity for a region of interest in order to detect and map on-going gliovascular unit metabolic activity using high-resolution 1H2O MRI. In one example approach, a computer-implemented method includes receiving a first set of DCE-MRI time-course data for a region, wherein a contrast agent is administered prior to imaging, identifying a region of interest from the first set of DCE-MRI time-course data for further analysis, performing shutter-speed pharmacokinetic analysis of the time-course data associated with the region of interest using computer-implemented software to obtain a finite and non-zero mean water molecule capillary lifetime in the region of interest, and indicating a level of cellular metabolic activity in the brain based on the mean water molecule capillary lifetime.
