C code generatio
n and the Simulink Accelerator and Rapid A ccelerator modes
are now support
ed for fixed-point and integer word lengths up to 128 bits.
The few excepti

arefortheAut

ROI support f
or Minimum and Maximum blocks
Full Region o
f Interest (ROI) support is available for the Minimum and
Maximum bloc
ks. Use the ROI type parametertospecifywhethertheROI
is a rectangl
e, line, label matrix, or binary mask. Full ROI processing is
available to
users who have a Video and Image Processing Blockset™ license.
If you only h
ave a Signal Processing Blockse t™ license, you can still use ROI
processing
, but are limited to the ROI type Rectangles.
New and Enha
nced Demos
The Video an
d Image Processing Blockset contain new and enhanced demos.
New Bar Code Recognition Demos
Two new demo
s using the Video and Image Processing Blockset to create
an image pr
ocessing system which can recognize and interpret a GTIN-13
barcode. T
he GTIN-13 barcode, formally known as EAN-13, is an international
barcode st
andard. It is a superset of the widely used UPC standard.
