  DeeperHistReg is a software framework dedicated to registering whole slide
images (WSIs) acquired using multiple stains. It allows one to perform the
preprocessing, initial alignment, and nonrigid registration of WSIs acquired
using multiple stains (e.g. hematoxylin \& eosin, immunochemistry). The
framework implements several state-of-the-art registration algorithms and
provides an interface to operate on arbitrary resolution of the WSIs (up to
200k x 200k). The framework is extensible and new algorithms can be easily
integrated by other researchers. The framework is available both as a PyPI
package and as a Docker container.
