With Bentley Descartes it is possible to create a seamless mosaic from a group of overlapping images representing different part of the a region. The Mosaic tool box contains two tools that will help you create mosaics, making all images look alike by changing the color and by cutting the overlapping sections and applying the feathering tool to hide the seam of the cut.
The Balance Tone tool is used to balance the tone of colors between all images of a mosaic and offers two modes to select from:
In addition to the two modes, the Balance Tone tool also allows you to define the Source Area by selecting the Entire Image, Overlap, Block, Oriented Block, Element or Fence.
The Define Seam tool is used to define the position of a seam between two overlapping images of a mosaic.
And example of this tools usage is shown below.
The following illustrates two overlapping images.
When using the Define Seam tool, dashed lines are drawn to indicate the following:
When processed, the top image is modified to create a seamless mosaic.
