摘要： The present invention includes a method for analyzing an image wherein elements defining a path within a two-dimensional image are received from a prescreener. A Sobel operator may be applied to the region around each of the elements of the chain to obtain a corresponding array of gradient directions. An angle correction may be applied to any of the gradient directions that goes beyond the highest value (in radian measure; the Pi −Pi transition), to obtain an array of gradient directions free of any artificial jumps in value. The gradient direction array (Sobel chaincode) can have its bandwidth taken to determine a single number of straightness so as to identify extremely straight edges, (manmade objects) from less straight edges (natural objects). A similar process can be used to analyze contours for straight sections, which are also parallel. These two and other filters applied to the gradient array can be part of a feature suite, for feature space analysis.

摘要： A computerized method, system for, and computer-readable medium operable to: determine a set of coordinates corresponding to a user's gaze; determine a user interface (UI) element corresponding to the set of coordinates; return that UI element as being detected and again repeating the determination of the set of coordinates corresponding to the user's gaze; determine if the UI element being returned is the same for a predetermined threshold of time according to a started timer; if the UI element is not the same, reset the started timer and again repeating the determination of the set of coordinates corresponding to the user's gaze; and if the UI element is the same, making the UI element active without requiring any additional action from the user and currently selecting the UI element to receive input.
