Intel Integrated Performance Primitives Library Upgraded and Support
Extended to maci64
The Intel
®
Integrated Performance Primitives (Intel IPP) Library has been upgraded
from Version 5.3.1 to Version 6.0 Update 1. Intel IPP Library support has been extended
to 64-bit Intel-based Mac computers.
Expanded hough Function Allows Specification of Arbitrary Theta Search
Space
The hough function now yields faster results for narrower theta ranges due to the
addition of a parameter/value pair for specifying theta values.
Compatibility Considerations
In previous releases, the 'ThetaResolution' parameter controlled the theta values for
the hough function. Now 'ThetaResolution' is being replaced by the new 'Theta'
parameter.

hough(BW,
'ThetaResolution',val)
Still runs hough(BW,'Theta',
-90:val:(90-val))
Input parameter
no longer
recommended.
Use new 'Theta'
parameter.
Note that with the introduction of the 'Theta' parameter, not all abbreviated forms of
'ThetaResolution' will still work. In previous releases, if you entered the following
syntax:
hough(BW, 'T', val)
'T' stood for 'ThetaResolution'. Now if you enter this same syntax, 'T' stands for
the new 'Theta' parameter.
If you have old code that uses the 'ThetaResolution' parameter, please see the
