 After that a slower one-to-all image comparison package [images4](https://github.com/vitali-fedulov/images4) should be used on the resulting image set produced with the approximate algorithm of package imagehash. This filtering sequence is necessary, because direct one-to-all comparison with Eucledian approach of images4 is not scalable for very large image sets.
 
-An alternative to using hashes4 package are generating multiple hash sets on different pixel sub-sets of the icon, so that search results of one hash set can be intersected with another, or several hash sets. Each intersection will improve the result. Look at var `HyperPoints10` description to understand how to create such different pixel sub-sets.
