Hough Transform

The Hough transform is a general technique that allows to detect the flat curves in binary images [Gon93]. The current version of Intel IPP implements the following:
  • Detection of the straight lines that are defined by the parametric equation:
    r
    =
    x
    *cos(
    Θ
    ) +
    y
    *sin(
    Θ
    )
    , where
    r
    and
    Θ
    are the length and angle from the origin of a normal to the line, respectively.
  • Detection of lines using the probabilistic Hough transform algorithm [Matas00].

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
