GPU acceleration for more than 20 functions, including bwmorph, edge,
imresize, and medfilt2
This release introduces GPU acceleration for a group of toolbox functions, listed below.
GPU acceleration for these functions requires Parallel Computing Toolbox software and
meeting the GPU computing requirements detailed here.

edge im2uint16 imlincomb rgb2ycbcr

Additional 2D geometric transformations: piecewise linear, local
weighted mean, and polynomial
The toolbox includes several new classes for representing 2D geometric transformations,
listed below.
images.geotrans.PiecewiseLinearTransformation2d2D piecewise linear geometric transformation
images.geotrans.PolynomialTransformation2d2D polynomial geometric transformation
images.geotrans.LocalWeightedMeanTransformation2d2D local weighted mean geometric transformation
Additional parameter in imregister and imregtform to specify
initial transformation
The imregister and imregtform functions both support a new parameter,
InitialTransformation, that enables you to specify the starting point for the
transformation. Specifying an initial geometric transformation as a starting point, the
functions can return better results.
