New ImageAdapter Class Supports Custom File Formats for blockproc
The blockproc function, introduced in R2009b, supported file-based block processing for
arbitrarily large images. In R2009b, you could use blockproc to read or write TIFF
images or to read JPEG2000 images. Now, with the addition of the new ImageAdapter
class, you can design your own class to use blockproc with images of arbitrary file
format.
The blockproc Function Now Supports Spatially Varying Operations
Additional fields have been added to the blockproc “block struct” that contain spatial
information. These new fields facilitate operations that depend on location.
Plot Selector Now Generates Plots for imshow and imtool
The Plot Selector workspace tool creates graphs of workspace variables. The imshow
and imtool functions have been added to the list of possible plotting functions available
in the Plot Selector. For more information about the Plot Selector, see Enhanced Plot
Selector Simplifies Data Display.
makecform Now Supports White Point Adaptation
makecform uses the white point specified by the International Color Consortium (ICC)
as the default for the srgb2lab and lab2srgb transform types. You can now adapt to a
white point other than whitepoint('ICC'), the default value, by using a new syntax to
specify the adapted white point:
C = makecform(type, 'AdaptedWhitePoint', WP)
You can also create a linear chromatic-adaptation transform:
C = makecform('adapt', 'WhiteStart', WPS, 'WhiteEnd', WPE, ...
'AdaptModel', modelname)
This transform allows you to adapt XYZ color values from one white point to another.
Intel Integrated Performance Primitives Library Support Extended to
imdilate, imerode, and medfilt2
The functions imdilate and imerode are now hardware optimized for ones(3)
neighborhoods for single, uint8, and uint16 input images.
