Wizard Page 2 - Segmentation interface
- Type - Choose the method of segmentation and set the
specific
parameters required.
- Region Growing
- Minimum segment size: A positive minimum segment
size (pixels number ).
- Similarity Threshold: Use lower values to merge
only those segments that are more similar - Higher values will allow
more segments to be merged - valid values range: positive values -
default: 0.1.
- Baatz
- Minimum segment size: A positive minimum segment
size (pixels number ).
- Similarity Threshold: Use lower values to merge
only those segments that are more similar -
Higher values will allow more segments to be merged - valid values
range: positive values - default: 0.1.
- Color Weight: The weight given to the color component,
default: 0.75, valid range: [0,1].
- Compactness Weight: The weight given to the
compactness component, default : 0.5, valid range: [0,1].
- Common Parameters:
- No Data: If checked, no
data value will be used as the no-data value for input rasters.
- Select the Input Bands to be segmented by checking its
box. For Baatz method, its is also possible to change Weight
(The weight given to each band (note: the bands weights sum must always
be 1) or an empty vector indicating that all bands have the same
weight.)
- Preview - optionally click on
to check
the segmentation of a small box of the image.
- Press Next
to go to next step, Back to check the previous wizard page or Cancel
to close the
dialog.
Wizard Page 3 - Segmentation Advanced parameters interface.
Optionally, use this page to change default values
of advanced parameters related with performance.
- Block options:
- Enable block processing:
If checked, the original raster will be split into small blocks,
each one will be segmented independently and the result will be merged
(if possible) at the end.
- Enable block merging:
If checked, a block merging procedure will be performed
- Thread options:
- Maximum block size: The
input image
will be split into blocks with this width for processing, this
parameter tells the maximum block lateral size (width or height). The
default behavior, the size will be defined following the current system
resources and physical processors number.
- Maximum threads
number: The maximum number of concurrent threads. The
default behavior is: automatically found.
Wizard Page 4 - Output
Raster information
- Raster Info
- First press
and inform the folder where the resulting
file will be saved.
- Name - inform
the raster name.
- Extra
Parameters - if there are some, see the details on how to inform
then here.
- Press Finish
to save the resulting segmented raster or Back
to go to the previous wizard page.
