For every pixel in source image 1, determine the pixel with the most similar intensity in the local neighborhood with a given radius in source image 2. Write the distance in X and Y in the two corresponding destination images.

particleImageVelocimetryTimelapse (Experimental)

Run particle image velocimetry on a 2D+t timelapse.

paste2D

Pastes an image into another image at a given position.

paste3D

Pastes an image into another image at a given position.

pointIndexListToMesh

Meshes all points in a given point list which are indiced in a corresponding index list.

pointlistToLabelledSpots

Takes a pointlist with dimensions nd with n point coordinates in d dimensions and a touch matrix of size nn to draw lines from all points to points if the corresponding pixel in the touch matrix is 1.

popMetaData (Experimental)

Takes meta data from a stack and assigns it to the current image. The stack implements the Last-In-First-Out (LIFO) principle.

power

Computes all pixels value x to the power of a given exponent a.

powerImages

Calculates x to the power of y pixel wise of two images X and Y.

preloadFromDisc (Experimental)

This plugin takes two image filenames and loads them into RAM. The first image is returned immediately, the second image is loaded in the background and will be returned when the plugin is called again.

presign (Experimental)

Determines the extrema of pixel values:

print

Visualises an image on standard out (console).

pull

Copies an image specified by its name from GPU memory back to ImageJ and shows it.

pullAsROI

Pulls a binary image from the GPU memory and puts it on the currently active ImageJ window as region of interest.

pullBinary

Copies a binary image specified by its name from GPU memory back to ImageJ and shows it. This binary image will have 0 and 255 pixel intensities as needed for ImageJ to interpret it as binary.

pullLabelsToROIList

Pulls all labels in a label map as ROIs to a list.

pullLabelsToROIManager

Pulls all labels in a label map as ROIs to the ROI manager.

pullString

Writes an image into a string.

pullTile (Experimental)

Pushes a tile in an image specified by its name, position and size from GPU memory.
