Detailed Description

Implements ImageJ's Subtract Background command. Based on the NIH Image Pascal version by Michael Castle and Janice Keller of the University of Michigan Mental Health Research Institute. Rolling ball algorithm inspired by Stanley Sternberg's article, "Biomedical Image Processing", IEEE Computer, January 1983.

Member Function Documentation

void run ( ImageProcessor  ip)
inline

Filters use this method to process the image. If the SUPPORTS_STACKS flag was set, it is called for each slice in a stack. ImageJ will lock the image before calling this method and unlock it when the filter is finished.

Implements PlugInFilter.

int setup ( String  arg,
ImagePlus  imp 
)
inline

This method is called once when the filter is loaded. 'arg', which may be blank, is the argument specified for this plugin in IJ_Props.txt. 'imp' is the currently active image. This method should return a flag word that specifies the filters capabilities.

Implements PlugInFilter.

void subtractBackround ( ImageProcessor  ip,
int  ballRadius 
)
inline

Implements a rolling-ball algorithm for the removal of smooth continuous background from a two-dimensional gel image. It rolls the ball (actually a square patch on the top of a sphere) on a low-resolution (by a factor of 'shrinkfactor' times) copy of the original image in order to increase speed with little loss in accuracy. It uses interpolation and extrapolation to blow the shrunk image to full size.
