Edge detection is a image processing technique used to identify boundaries within digital images. By definition, edges are sudden changes in image brightness.
Photoshop uses edge detection algorithms to find these sudden changes and create a mask from them. This mask can then be used to create various effects, like increasing image contrast or creating selective colorization.
There are a few different ways to use edge detection in Photoshop. One is to use the “Find Edges” filter, which can be found under the “Filter” menu.
This filter will automatically find and create a mask from the edges in your image. Another way to use edge detection is to create a “Layer Mask” from the “Select” menu. This will allow you to manually select which areas of your image you want to apply the edge detection effect to.
PRO TIP: This article contains information about how to use edge detection in Photoshop. It is important to note that this technique can result in images that appear to be low quality.
Edge detection can be a useful tool for increasing image contrast or creating interesting effects. However, it is important to remember that this technique will only work on images with sharp boundaries. If your image does not have clearly defined edges, the results may not be as desired.
