|step 1: prepare image and shapefiles|
|step 2: learn about PCIDSK database structure |
|step 3: the 4SM command line|
|step 4: the AutoCAL script|
Compute glint regressions
Write the special effects mask in channel 4
Extract the calibration data text file
Perform an automatic calibration
Display a preliminary calibration diagram
Write the 4sm.def defaults file
Write and display the 4SM command line for the next step
|step 6: about the segmentation of the image|
|step 7: things you can do|
|next to Deglint-and-Investigate-your-image|
|Activity in directory ./data. |
Your script is ready.
Now you need to prepare your image.
LINE 1 prepapre your image
|Your work directory content should look like this |
Export from tarawa-full.tif to PCIDSK tarawa-full.pix
Raw data is stored in data/tarawa-full.tif
Now you draw several shapefiles inside your import areaand save them in the work directory, ready for use in the AutoCAL process.
you don't need to do anything here,
as all shapefiles are provided for you in this tutorial,
-unless/until you want to try your own shapefiles-
Relative path for shapefiles
Absolute paths in OpenEV projects are a pain!
|The PCIDSK file structure is specified in the -DB... commandline argument |
./data/tarawa-full.pix and ./shapefiles.shp are now available.
FILE interleaving is most handy
|Upon execution of 4SM, |
|./tarawa_subset.mcd text file |
|Learn about the special effect mask mSE |
