 ### + **kook\*** / Hough transform
 
-Two `pp.kook*(...)` functions are included with this program, which fit circles to features in the image using the Hough transform and the pre-processing steps described by [Kook et al. (2015)][kook]. 
+Two `pp.hough_kook**(...)` functions are included with this program, which fit circles to features in the image using the Hough transform and the pre-processing steps described by [Kook et al. (2015)][kook]. 
 
-The first function, `pp.kook(...)`, contains a copy of the code provided by [Kook et al. (2015)][kook], with minor modifications to match the input/output of some of the other packages — namely to take a single image, `img`, and a pixel size, `pixsize` — and to output a `Pp` structure, which contains information for each circle. Note that the original function acts on images without trying to assign primary particles to an aggregate, something resolved in the second function below. This causes some compatibility issues in terms of comparing the output from this function to the other methods contained in this program.

-The `pp.kook2(...)` function contains a modified version of the method proposed by [Kook et al. (2015)][kook] that excludes circles in the background and assigns primary particles to aggregates. This is done rather simply:  by checking if the center of the circles from the preceding procedure lie within the binary for a given aggregate. A sample output is as follows.
