Lijun Zhu 93ca4bf96d PyCuAmpcor: add sum_area_table based correlation surface normalization to allow arbitrary window size (used to be limited by the 1024 max cuda threads) 2021-04-13 10:08:29 -07:00
Zhang Yunjun d81a98094e cuDenseOffsets: add prepareGeometry()
PyCuAmpcor/examples/cuDenseOffsets:
+ add prepareGeometry() to generate the cooresponding geometry file
+ update file path in xml file to support dir change
+ fix str.decode bug with try/except statement
+ printout used time
+ check --redo before initiate PyCuAmpcor to avoid the long GPU memory error message

PyCuAmpcor/README.md: fix typos for ROIPAC

Lijun Zhu 7c40da5a74 PyCuAmpcor: offer an option to add gross offset to output offset image 2021-02-16 13:02:04 -08:00
Lijun Zhu 4ddee2fdaf PyCuAmpcor: fix the help string in cuDenseOffsets.py 2021-02-06 12:02:34 -08:00
Lijun Zhu 7e9c86910a PyCuAmcpor: set default gpu id to 0 in cuDenseOffsets.py; the auto seek with a negative value is now disabled 2020-12-15 13:33:34 -08:00
Lijun Zhu 6d9f088975 PyCuAmpcor: cuDenseOffsets.py towork with input varying gross offsets 2020-11-30 10:30:23 -08:00
Lijun Zhu a393282b69 PyCuAmpcor updates:
* added a README.md for installation/user guide/procedures

  * modified the cuDenseOffsets.py
     * expose more options from the CUDA/C++ program
     * add an option for varying gross offset input
     * clarify the parameter definitions

  * removed old SlcImage implementation and cublas dependence

  * modified cuSincOversampler
    * to be consistent with cpu version
    * fix an issue when the extraction of the search window is not around the center

  * added a debug mode to output intermediate results

  * enable cuda error checking for both Debug/Release build types

  * corrected the code to extract raw images when the correlation surface peak is close to edges

  * Move utf-8 decoding step inside cython extension

    The cython setters take python strings, but the getters return
    python bytes, so this makes the types match up. I went with regular
    python strings for the interface since they are more common at the
    python level, so the encoding/decoding is now an implementation detail
    of the cython extension.

Paul A Rosen e03042f4e5 diversity: replaced oppressive language with neutral definitions of the images that comprise an interferogram through the entire repository 2020-07-02 12:40:49 -07:00
Zhang Yunjun c642ab2e9a cuDenseOffset: check across oversample win size 2020-06-28 19:24:09 -07:00
Zhang Yunjun 90d578fa5d cuDenseOffsets: expose --raw-osf and --corr-win-size option
contrib/PyCuAmpcor/cuDenseOffsets.py:
+ expose --raw-over-samp-factor option to change the raw data oversampling factor with default of 2
+ expose --corr-win-size option, which by default, is calculated automatically based on the search window size and raw oversampling factor
+ change the namespace key for the oversampling factor of correlation surface from 'oversample' to 'corr_oversample' to avoid ambiguity, the cmd option name is still the same, thus no different in the user side.
+ use vrt file for master / slave slc data loading folllowing https://github.com/isce-framework/isce2/pull/78
+ re-organize createParse() for readability
+ add example to argparse help

stripmapStack/MaskAndFilter.py:
+ fix a bug introduced in #https://github.com/isce-framework/isce2/pull/112
+ add example usage to help message
+ mask pixels with SNR == 0, for plotting only without touching data files
+ show input parameter in the figure title
+ show percentage after SNR thresholding
+ add interpolation for matplotlib while plotting

topsStack/grossOffsets: move obsolete basemap import from the top to the related commented code block
