Hello, thanks for sharing this tool. I'm trying to run it on a dataset I have for a dune field in South Brazil. The examples worked fine, but with my data, it crashes:
guano:GPIV-master$ gpiv piv dem_als_bilinear_step_2.tif dem_sfm_bilinear_step_2.tif 200 200 Computing PIV. /usr/local/lib/python3.7/site-packages/skimage/feature/template.py:165: RuntimeWarning: invalid value encountered in greater mask = denominator > np.finfo(np.float64).eps Traceback (most recent call last): File "/usr/local/bin/gpiv", line 10, in <module> sys.exit(cli()) File "/usr/local/lib/python3.7/site-packages/click/core.py", line 764, in __call__ return self.main(*args, **kwargs) File "/usr/local/lib/python3.7/site-packages/click/core.py", line 717, in main rv = self.invoke(ctx) File "/usr/local/lib/python3.7/site-packages/click/core.py", line 1137, in invoke return _process_result(sub_ctx.command.invoke(sub_ctx)) File "/usr/local/lib/python3.7/site-packages/click/core.py", line 956, in invoke return ctx.invoke(self.callback, **ctx.params) File "/usr/local/lib/python3.7/site-packages/click/core.py", line 555, in invoke return callback(*args, **kwargs) File "/usr/local/lib/python3.7/site-packages/gpiv.py", line 45, in piv propagate, output_base_name) File "/usr/local/lib/python3.7/site-packages/piv_functions.py", line 30, in piv False, output_base_name) File "/usr/local/lib/python3.7/site-packages/piv_functions.py", line 135, in run_piv if (correlation_max[0][0]==0 or IndexError: index 0 is out of bounds for axis 0 with size 0 guano:GPIV-master$
image size is 1849 x 3440, would that be the issue?
