Version 2.3 (R2007a ) Video and Image Processing Blockset™
Block Parameter
s Support Additional Data Types
Previously, the
Video and Image Proces sing Blockset block dialog box
parameters supp
orted only double-precision, floating-point data types. They
now support addi
tional data types. For more information about Sim ulink data
types, see “Spe
cifying Numeric Parameter Val ues” and “Working with Data
Types” in the Si
mulink documentation.
Color Data Mana
gement Simplified Using 3-D Array
Representati
on
Video and Imag
e P rocess ing Blockset enables you to work with color images
and video sign
als as multidimensional arrays. This change improves the
usability of t
he blockset. For more information, see “Color Image Processing”
in the Video a
nd Image Processing Blockset User’s Guide.
Compatibility Considerations
If you open an
old model that links to a block that now supports
multidimens
ional arrays, an asterisk appears next to the model name, and
you are prom
pted to sav e the model before y ou close it. After y ou save the
model, you w
on’t experience this behavior again.
