Image Processing Addition The operand value (constant or Operand image pixel) is added to the corresponding pixel in the input image. The result is scaled and clipped, and finally written to the output image. Subtraction The operand value (constant or Operand image pixel) is subtracted from the corresponding pixel in the input image. The result is scaled and clipped, and finally written to the output image. Division The input image pixel value is divided by the operand value (constant or corresponding Oper- and image pixel). The result is scaled and clipped, and finally written to the output image.
Multiplication The input image pixel value is multiplied by the operand value (constant or corresponding Operand image pixel). The result is scaled and clipped, and finally written to the output image. Lightest (Maximum) The operand value (constant or Operand image pixel) and corresponding pixel in the input image are compared to find the maximal value. The result is scaled and clipped, and finally written to the output image. Darkest (Minimum) The operand value (constant or Operand image pixel) and corresponding pixel in the input image are compared to find the minimal value. The result is scaled and clipped, and finally written to the output image.
Assignment Operations Assignment operations promote the input values of the source pixels and the Operand values to the more defined type, based on the input image, the Operand image or the desired output image type. This type of operation does not support scaling or clipping. The Image Processing Tool provides the following assignment operations: Initialization, Copy and Inversion. Initialization All the pixels of the output image are set to a specific constant value. The height and width of the output image must be specified. Copy Each input image pixel is copied to the corresponding output image pixel. ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 511
