4.7 Image Filters
Filters Toolbox with 3-D (contour) selected
AlphaEaseFC™ includes a variety of enhancement filters that can improve the
appearance of an image. Some filters sharpen detail, others smooth and reduce random
noise. Still others help visualize edges and separate closely spaced bands or objects.
Depending upon the unique characteristics of an image, the results of each filtering
operation vary. Assess the characteristics of the image and then select the filter designed
to minimize its imperfections.
When an image is filtered, the original image information is replaced with the results of
the filtering operation. As a result, the original image information is altered. To avoid
losing the original image, save it as an original TIFF file before applying a filter.
When the FILTERS button in ToolBox, Enhancement Tools is selected, a pop-up box
appears. If the desired filter is not shown, choose MORE to display more filters. One or
many filters can be applied to a single image.
