In this tutorial, we'll cover the advantages and disadvantages of using the extraction filter in Photoshop, as well as how to use it. To begin, open the Filter menu and select Extract.

But there is a time difference between extraction and Refine Edges, so Extract is often the best choice for still photo editors. The extraction filter works by using 2D convolution. This is a filtering operation that uses two images: one as an input image and the other, called the core, serves as a filter. The mathematics of many filters can be expressed primarily using 2D convolution, such as smoothing and focusing images and detecting edges.

The moving average filter is one example of a 2D convolution filter. It replaces each pixel with the average pixel value thereof and a neighborhood window of adjacent pixels. Correlation is another type of filtering operation that measures the similarity of two signals, comparing them as they move relative to each other. Now that you know how to use the extraction filter in Photoshop CS3, you can easily remove an image from its background with just a few clicks.
