Abstract: By sequentially scanning pixel lines of an image signal that has been received as input linear interpolation application regions, which are regions in which gray-level changes are to be smoothed, are detected for each line of the input signal, and the detected linear interpolation application regions are then subjected to an gray-level extension process. The regions that have been subjected to the gray-level extension process are further subjected to a process of limiting, to within prescribed values, gray-level changes in a second direction that differs from the direction in which the linear interpolation application region detection process was carried out.

Abstract: A method for automated selection of image regions (“tiles”) in an overall image includes computing a gray-level co-occurrence matrix and entropy of a green plane of the overall image, applying morphological closing to the matrix and thresholding the matrix and entropy image to provide binary masks. The matrix and entropy masks are combined with a vignette mask, the combination indicating areas of acceptable tissue from which tiles are selected randomly. For cancer grading; image data is transformed to Hue, Saturation and Value; for steroid/protein expression analysis it is transformed to cyan and a Sobel of cyan is computed. A feature measure is computed for each tile based on color and texture, and is carried out randomly but influenced by feature measure. Finally, from the further selection, tiles are chosen which combine high feature measure with low overlap.

Abstract: There is provided a real-time tracking system and a method associated therewith for identifying and tracking objects moving in a physical region, typically for producing a physical effect, in real-time, in response to the movement of each object. The system scans a plane, which intersects a physical space, in order to collect reflection-distance data as a function of position along the plane. The reflection-distance data is then processed by a shape-analysis subsystem in order to locate among the reflection-distance data, a plurality of discontinuities, which are in turn associated to one or more detected objects. Each detected object is identified and stored in an identified-object structure. The scanning and processing is repeated for a number of iterations, wherein each detected object is identified with respect to the previously scanned objects, through matching with the identified-object structures, in order to follow the course of each particular object.

Abstract: A system identifies a change in a position of an object from a first frame to a second frame from a plurality of frames. The video is comprised of a plurality of frames. In one embodiment, the plurality is at least three frames. The image stability measuring process identifies a change in direction of the change in the position of the object. The change in direction is determined by utilizing a plurality of adjacent frames located near the first frame and the second frame. The image stability measuring process determines an image stability value for a subset of the plurality of frames. The image stability value is calculated based on the change in direction. The image stability measuring process renders a portion of the video within an automatic editing script. The portion of the video is selected based on a preferred image stability value identified within the automatic editing script.
