DirectConvolution (Fiji Javadocs 0-SNAPSHOT API)

java.lang.Object
- mpicbg.imglib.algorithm.ROIAlgorithm<T,S>
- - mpicbg.imglib.algorithm.roi.DirectConvolution<T,R,S>

Type Parameters:

T - input image type

R - kernel type

S - output image type

All Implemented Interfaces:

Algorithm, Benchmark, OutputAlgorithm<S>

Direct Known Subclasses:

DirectCrossCorr
```
public class DirectConvolution<T extends RealType<T>,R extends RealType<R>,S extends RealType<S>>
extends ROIAlgorithm<T,S>
```
DirectConvolution is an ROIAlgorithm designed to do both convolution and cross-correlation by operating on the image and kernel directly, rather than by using such time-saving tricks as FFT.

  Description copied from class: ROIAlgorithm
  
  Performs this algorithm's operation on the patch represented by a RegionOfInterestCursor
  
  Specified by:
  
  patchOperation in class ROIAlgorithm<T extends RealType<T>,S extends RealType<S>>
  
  Parameters:
  
  position - the position in the input image at the center of the patch represented by the RegionOfInterestCursor
  
  roiCursor - a RegionOfInterestCursor that iterates over the given patch-of-interest
  
  Returns:
  
  true if the operation on the given patch was successful, false otherwise. If false is returned by this method, process() will abort.
- checkInput
```
public boolean checkInput()
```
  Specified by:
  
  checkInput in interface Algorithm
  
  Overrides:
  
  checkInput in class ROIAlgorithm<T extends RealType<T>,S extends RealType<S>>
