Differences between Matlab and Python implementations

NoRMCorre is implemented both in Matlab (this package), and in Python as part of the CaImAn package. While the algorithm is the same in both cases and the results almost identical, there are several minor differences in the two implementations and their features. We highlight these differences on the following table

Feature/Property	Matlab	Python
online template updating	YES	NO
available shifts	FFT	FFT, bicubic
handles 3d data	YES	NO
optical flow calculation	NO	YES
overlap included in the size variable	NO	YES
FFT windowing	YES	NO
parallelization method	for each mini batch process different frames in parallel	process different mini batches in parallel
variable for grid size	grid_size	strides
overlap included in grid size	NO	YES
total size of each patch	grid_size + 2*overlap	strides
