vertical gradient measure and returns the square-root of the sum of
the two squared signals.
- *%(M_PREWITT)s:* Finds edges using the %(M_PREWITT)s approximation
to the derivative. It returns edges at those points where the
gradient of the image is maximum.
- *%(M_ROBERTS)s:* Finds edges using the Roberts approximation to the
derivative. The %(M_ROBERTS)s method looks for gradients in the
diagonal and anti-diagonal directions and returns the square-root of
the sum of the two squared signals. This method is fast, but it
creates diagonal artifacts that may need to be removed by smoothing.
- *%(M_LOG)s:* Applies a Laplacian of Gaussian filter to the image and
finds zero crossings.
- *%(M_CANNY)s:* Finds edges by looking for local maxima of the
gradient of the image. The gradient is calculated using the
derivative of a Gaussian filter. The method uses two thresholds to
detect strong and weak edges, and includes the weak edges in the
output only if they are connected to strong edges. This method is
therefore less likely than the others to be fooled by noise, and more
likely to detect true weak edges.

compass points (North, North-east, etc.) and selecting the maximum as
the pixel’s value.

- *%(SCHEME_RGB)s*: Each input image determines the intensity of one
of the color channels: red, green, and blue.
- *%(SCHEME_CMYK)s*: Three of the input images are combined to
determine the colors (cyan, magenta, and yellow) and a fourth is used
only for brightness. The cyan image adds equally to the green and
blue intensities. The magenta image adds equally to the red and blue
intensities. The yellow image adds equally to the red and green
intensities.
- *%(SCHEME_STACK)s*: The channels are stacked in the order listed,
from top to bottom. An arbitrary number of channels is allowed.
For example, you could create a 5-channel image by providing
5 grayscale images. The first grayscale image you provide will fill
the first channel, the second grayscale image you provide will fill
the second channel, and so on.
- *%(SCHEME_COMPOSITE)s*: A color is assigned to each grayscale image.
Each grayscale image is converted to color by multiplying the
intensity by the color and the resulting color images are added
together. An arbitrary number of channels can be composited into a
single color image.

guiding objects within that grid compartment. Thus, if a guiding
object lies within a particular grid compartment, that object’s
center will be the center of the created circular object. If no

The final projection image can be created by the following methods:
- *%(P_AVERAGE)s:* Use the average pixel intensity at each pixel
position.
- *%(P_MAXIMUM)s:* Use the maximum pixel value at each pixel position.
- *%(P_MINIMUM)s:* Use the minimum pixel value at each pixel position.
- *%(P_SUM)s:* Add the pixel values at each pixel position.
- *%(P_VARIANCE)s:* Compute the variance at each pixel position.
The variance method is described in Selinummi et al (2009). The
method is designed to operate on a Z-stack of brightfield images
taken at different focus planes. Background pixels will have
relatively uniform illumination whereas cytoplasm pixels will have
higher variance across the Z-stack.
- *%(P_POWER)s:* Compute the power at a given frequency at each pixel
position.
The power method is experimental. The method computes the power at a
given frequency through the Z-stack. It might be used with a phase
contrast image where the signal at a given pixel will vary
sinusoidally with depth. The frequency is measured in Z-stack steps
and pixels that vary with the given frequency will have a higher
score than other pixels with similar variance, but different
frequencies.
- *%(P_BRIGHTFIELD)s:* Perform the brightfield projection at each
pixel position.
Artifacts such as dust appear as black spots that are most strongly
resolved at their focal plane with gradually increasing signals
below. The brightfield method scores these as zero since the dark
appears in the early Z-stacks. These pixels have a high score for the
variance method but have a reduced score when using the brightfield
method.
- *%(P_MASK)s:* Compute a binary image of the pixels that are masked
in any of the input images.
The mask method operates on any masks that might have been applied to
the images in a group. The output is a binary image where the “1”
pixels are those that are not masked in all of the images and the “0”
pixels are those that are masked in one or more of the images.
You can use the output of the mask method to mask or crop all of the
images in a group similarly. Use the mask method to combine all of
the masks in a group, save the image and then use **Crop**,
**MaskImage** or **MaskObjects** in another pipeline to mask all
images or objects in the group similarly.

*(Used only if a grayscale image is to be used as a guide for

You can use one of two methods to determine whether two objects should
merged, assuming they meet the distance criteria (as specified
above):
- *%(CA_CENTROIDS)s:* When the module considers merging two objects,
this method identifies the centroid of each object, records the
intensity value of the dimmer of the two centroids, multiplies this
value by the *minimum intensity fraction* to generate a threshold,
and draws a line between the centroids. The method will merge the two
objects only if the intensity of every point along the line is above
the threshold. For instance, if the intensity of one centroid is 0.75
and the other is 0.50 and the *minimum intensity fraction* has been
chosen to be 0.9, all points along the line would need to have an
intensity of min(0.75, 0.50) \* 0.9 = 0.50 \* 0.9 = 0.45.
This method works well for round cells whose maximum intensity is in
the center of the cell: a single cell that was incorrectly segmented
into two objects will typically not have a dim line between the
centroids of the two halves and will be correctly merged.
- *%(CA_CLOSEST_POINT)s:* This method is useful for unifying
irregularly shaped cells that are connected. It starts by assigning
background pixels in the vicinity of the objects to the nearest
object. Objects are then merged if each object has background pixels
that are:
- Within a distance threshold from each object;
- Above the minimum intensity fraction of the nearest object pixel;
- Adjacent to background pixels assigned to a neighboring object.
An example of a feature that satisfies the above constraints is a
line of pixels that connects two neighboring objects and is roughly
the same intensity as the boundary pixels of both (such as an axon
connecting two neurons' soma).""" % globals(),
