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.
