Remarks

  • For EdgeDetection, the results are the same for opposite angles. For example, angles 0 and 180 have the same result when used with the edge detection mask.
  • When an image undergoes image convolution each pixel of the image is multiplied by a mask to create a new pixel value. The mask is an array of values that describes the weight that should be given to each of the pixels surrounding a specific pixel. The new pixel value is the result of the mask sum being divided by the mask weight. Using different masks result in different alterations of the image. The masks used in this command result in different types of edge detection.
  • As an example of the different masks, consider the following example:
  • To obtain these images, the following settings were used:
    Parameters Emboss Edge ESplotch Splotch
    Angle 0 0 180 0
    Depth 3 3 3 3
    Height 250 250 100 100

  • This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support 32-bit grayscale images.
