    Remarks
    Here is a "good" sequence of operations for image processing:
    1. Despeckle an image (Despeckle method)
    2. Deskew an image (Deskew method)
    3. Detect image border (DetectBorder method)

    Possible values for scanIntervalX and scanIntervalY parameters: 1 - every column (row) will be scanned, 2 - every second column (row) will be scanned, 3 - every third column (row) will be scanned, and so on. Big values of these parameters may speed up deskewing process, but may worsen results.
