Edge Preserving Smoothing
- Simple smoothing destroys
the sharpness of images
- The reason is that the
filter treats edge points and area points identical
- HALCON 7.1 offers a new
filter which implements the latest research results of
anisotropic diffusion

|
:: Intelligent noise removal can ease many blob analysis
applications |
| |
Input image with noise
and
blurred edges
|
|
"parabolic" is
proven to be
the best algorithm but returns
the
smoothest edge
|
| |
"perona-malik"
has some
theoretical limitations but
provides
perfect edges in
virtually all practical
applications
|
|
"weickert" can
be used to not
only smooth areas but also
to
sharpen edges
