 ## Example 
 
-Let us take a look at a simple example where the BRIEF descriptor is used to match two images where one has been translated by `(10, 20)` pixels. We will use the `lena_gray` image from the [TestImages](https://github.com/timholy/TestImages.jl) package for this example.

 First, let us define a warping function to transform the image.
