+focus-stack is an application for fast and easy focus stacking.
+
+It takes a series of photographs captured from the same location but
+a different focus distances and then combines them to create a single
+photograph so that the complete subject is in focus. This is commonly
+called extended depth of field, or focus stacking. Typical use is for
+microscope photography where it is difficult to obtain large enough
+depth of field to cover the whole subject. The focus stacking
+algorithm used was invented and first described in "Complex Wavelets
+for Extended Depth-of-Field: A New Method for the Fusion of
+Multichannel Microscopy Images" by B. Forster, D. Van De Ville, J.
+Berent, D. Sage and M. Unser. The application also uses multiple
+algorithms from OpenCV library. Most importantly, findTransformECC
+is used to align the source images.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+focus-stack: focus-stack (Fast and easy focus stacking)
+focus-stack:
+focus-stack: focus-stack takes a set of photos taken at different focus settings
+focus-stack: and combines them into one, selecting the sharpest source image for
+focus-stack: each pixel position. This is commonly called extended depth of field,
+focus-stack: or focus stacking. Typical use is for microscope photography where it
+focus-stack: is difficult to obtain large enough depth of field to cover the whole
+focus-stack: subject. This application uses OpenCV library and its OpenCL
+focus-stack: acceleration interface.
