◆ adaptiveThreshold() [1/2]
|
static |
Finds the optimal binary threshold value and radius of the smallest enclosing circle.
Applies increasing threshold values staring at the median value and finds the
radius of the smallest enclosing circle. Uses a trailing window of specified size
to determine where the radius values start to "level off" (i.e. where the coefficent
of variance of the radius in the window is less than the specified value).
Parameters
----------
image : ndarray
2D image on which to get the threshold
variationLimit: float
The coefficient of variation for the radii in the window at which to accept the
threshold value. For example,a value of 0.005 corresponds to the point where the
standard deviation of the radii in the window is less than 0.5% of the mean.
windowSize: int
The size of the trailing window. i.e. The number of past radii to consider when
determining where the values "level off." Note that this number must be less than
or equal to the thresholdStart value.
Returns
-------
center : tuple of float
The center of the circle. The mean x and y coordinates in the window are returned.
radius : float
The radius of the circle. The mean radius of the window is returned.
imageMask : ndarray
2D mask array for the threshold value.
Raises
------
CcdTrackServiceException

kernelSize : int, optional
If specified, uses a kernel of this size to 'open' then 'close' the image. This may help to reduce noise
and ensure better contour fitting.
Returns
-------
center : tuple of float
Center of the enclosing circle in (x, y) coordinates
radius : float
Radius of the enclosing circle.
imageMask : ndarray
2D mask array used to find the enclosing circle

----------
shift : ndarray
The x, y, z shifts (in pixels) to track.
