Merge pull request #1701 from pijyoi/fix_overflow_warning
avoid numpy scalar overflow
2021-04-08 21:54:23 -07:00

3be8cafff4 avoid numpy scalar overflow
the "offset" argument passed into rescaleData() is typically an element
of an ndarray, i.e. it comes from the lower bound value of the "levels"
ndarray. as such, arithmetic operations on it can overflow.

this triggers a runtime warning in the test suite.

the workaround is to convert it to a Python (integer) scalar.

Fix roi get array region (#1700)
* ROI.py, getArrayRegion: Fix return mapped coordinates

The *getArrayRegion* method is defined as returning a tuple of the points
in the selected region and the mapped coordinates if the
*returnMappedCoords* keyword argument is set to True in the parent class
*ROI*.

In the *EllipseROI* class, *getArrayRegion* was overriden, however it
ignores the *returnMappedCoords* keyword argument, leading to unintended
bugs because of the change in interface between the parent class and
the subclass.

This patch fixes the above bug.
If *returnMappedCoords* is set to False, then only *arr* containing the
array region is returned. If *returnMappedCoords* is set to True, a
tuple of the array region and the mapped coordinates is returned.

NB: At the time of this commit, the same bug is present in several classes
extending *ROI*. This commit only fixes the issue for the *EllipseROI* class.

* ROI.py, PolyLineROI.getArrayRegion: Fix return mapped coordinats

points in the selected region and the mapped coordinates if the
*returnMappedCoords* keyword argument is set to True in the parent class

False, then only *arr* containing the array region is returned. If
*returnMappedCoords* is set to True, a tuple of the array region and the
mapped coordinates is returned.

fda8731dab reduce memory usage during data generation
random.normal() generates as float64 and gets converted to a smaller
dtype. generating all the needed data in a single call thus uses a lot
more memory than is necessary.

this changes it such that smaller chunks are generated.
data clipping is also changed to be in-place.

the gaussian filtering which gave the video a washed-out look is also
removed. this also contributed to data generation time.
