0.2.0-RC2

• Added hybrid compare
• Flagged naive RGB compare as useless as it actually is in readme.md :)

0.2.0-RC1

First RC of 0.2.0 featuring:

• RGB image comparison for structure
• Grayscale histogram comparisons using different distance metrics

0.1.1 - Patch-Release for MSSIM

Fixed two flaws in MSSIM:

• smaller border-windows where taken into the mean as full windows given contained border pixels more weight (very small effect < 1e4 in examples / tests).

• sub-windows of the image where not correctly shifted resulting in bordering pixels being used double (small effect ~0.01 in examples/tests)

• Added more tests

• Added a new trait to allow easy conversion of SimilarityImage to grayscale

• Added tests for this (see cucumber-tests for examples :) )

0.1.0

Basic first release
