Detailed Description

Represents a selector for regions based on various criteria.

ids_peak_icv 1.1

Constructor & Destructor Documentation

__init__()

None __init__	(		self,
		RegionArray	regions )

Creates a region selector.

It is possible to provide an empty numpy array (no regions), but it does not make sense, because in this case no regions can be selected.

Parameters

regions

List of Region objects to select from.

Exceptions

NotSupportedException

If regions is not a numpy array.

Member Function Documentation

_select_by()

RegionSelector _select_by ( self, Callable select_by_get_count_function, Callable select_by_function, ctypes.Structure c_interval )

protected

regions()

RegionArray regions

(

self

)

Get the selected regions.

Returns

List[Region]: List of selected Region objects.

Since

ids_peak_icv 1.1

select_by_area()

RegionSelector select_by_area	(		self,
		Interval	interval )

Select regions based on their area.

Parameters

interval

Interval to select by. Only positive values are allowed.

Returns

RegionSelector: New RegionSelector object with selected regions.

Exceptions

NotSupportedException	If interval has a wrong type or the interval is not valid for this function.
NotPossibleException	If interval has atleast one negative component.

RegionSelector select_by_center_of_gravity_rect	(		self,
		Union[ Rectangle, Tuple[float, float, float, float], List[float], Tuple[int, int, int, int], List[ int]]	rect )

Select regions based in the center of gravity's position within a rectangle.

Parameters

rect	Rectangle to select by.

Returns

RegionSelector: New RegionSelector object with selected regions.

Exceptions

NotSupportedException

If interval has a wrong type or the interval is not valid for this function.

Select regions based on the center of gravity's x coordinate.

Parameters

interval

Interval to select by.

Returns

select_by_center_of_gravity_y()

RegionSelector select_by_center_of_gravity_y	(		self,
		Union[ Interval, Tuple[float, float], List[float], Tuple[int, int], List[int]]	interval )

Select regions based in the center of gravity's y coordinate.

Parameters
