View source for NC353L-PHG Post-Processing

==Procedures done at the post-processing stage==
* Applying pixel mapping information
* Aberration correction
* Distortion correction
* Vignetting correction
* Color correction
* Denoising
* Sharpening

==Requirements==
* Linux OS (Kubuntu preferably).
* [[Elphel_Software_Kit_for_Ubuntu#ImageJ_and_Elphel_plugins_for_imageJ|ImageJ and Elphel plugins]].
<!--
* Place [http://eyesisbox.elphel.com/post-processing/ImageJ/plugins/loci_tools.jar loci_tools.jar] into '''ImageJ/plugins/'''.
* Place [http://eyesisbox.elphel.com/post-processing/ImageJ/plugins/tiff_tags.jar tiff_tags.jar] into '''ImageJ/plugins/'''.
-->
* Calibration data (come with camera)
* default-config.corr-xml (comes with camera)

==Instructions==
* Launch ImageJ from Eclipse
* Go to '''Plugins''' -> '''ImageJ-Elphel''' -> '''Eyesis Correction'''
 '''Note''': if plugin needs to be recompiled - '''Plugins''' -> '''Compile & Run'''. Find and select '''Eyesis_Correction.java'''.

* '''Restore''' button -> browse for ''default_config.corr-xml'' (restores parameters for '''Configure correction''')
* '''Configure correction''' button - make sure that the following paths are set correctly (if not - mark the checkboxes - a dialog for each path will pop up):
<font size='2'>
 '''Source files directory'''                - directory with the footage images
 '''Sensor calibration directory'''          - [YOUR-PATH]/calibration/sensors
 '''Aberration kernels (sharp) directory'''  - [YOUR-PATH]/calibration/aberration_kernels/sharp
 '''Aberration kernels (smooth) directory''' - [YOUR-PATH]/calibration/aberration_kernels/smooth
 '''Equirectangular maps directory(may be empty)''' - [YOUR-PATH]/calibration/equirectangular_maps (it should be created automatically if the w/r rights of [YOUR-PATH]/calibration allow)
 
 '''Source file suffix''' - '''.jp4''' if jp4 files are processed
 '''Sensor files prefix''' - the format is '''<prefix>NN.calib-tiff''' - '''<prefix>''' is blank if the files are just ''NN.calib-tiff''. For '''XXX-NN.calib-tiff''' the prefix would be '''XXX-'''
 '''Sensor files suffix''' - default is '''.calib-tiff'''
 '''Kernel files (sharp)/(smooth) prefix - same rule as for the sensor files
 '''Kernel files (sharp)/(smooth) suffix''' - default is '''.kernel-tiff'''
 '''Equirectangular maps prefix''' - same rule as for the sensor files
 '''Equirectangular maps suffix''' - default is '''.eqr-tiff'''

</font>
* '''Configure warping''' (''Skip if the files already exist'') -> rebuild map files - this will create maps in [YOUR-PATH]/calibration/equirectangular_maps. Will take ~5-10 minutes.
* '''Select source files''' -> select all the footage files to be processed.
* '''Process files''' to start the processing.
