 Abstract. A new concept of implicit (hypothetical) reconstruction of patch pattern dynamics from single date photography is presented, based on gradients in the surface properties reflected by spatial variation in photographic brightness. Changes in the characteristics of patch patterns formed, follow generalized relationships of mutuality and complementarity between fragmentation and shape distribution. Utilizing two images from the beginning and the end of the fragmentation processes may provide a full implicit description of patch pattern dynamics. ALGORITHM: Implicit Patch Pattern Evolution from a single date air photograph is obtained by employing the following simple iterative process of progressive image partitioning: For threshold gray level = 0 to N For all image pixels If pixel gray level <= threshold graylevel then pixel value= 0 else pixel value=1 The result of this process is N+1 binary images that represent a patch pattern's change ranging from the absolute dominance of the background formation (e.g., white ) to the complete covering of the foreground formation (e.g., black) or vice versa. |
