Picture Recognition.
Abstract
The report reviews methods of measuring properties of pictures, and extracting objects from pictures, for purposes of picture recognition and description. Topics covered include: Properties of regions in pictures -- in particular, textural properties; detection of objects in pictures -- template matching, edge detection; properties of detected objects -- projections, cross-sections, moments; object extraction -- thresholding, region growing, tracking; properties of extracted objects -- connectedness and counting, area and perimeter, compactness, convexity, elongatedness; and, object and picture representation -- boundaries, skeletons, relational structures.
