Method Details

applyRankFilter

public static Channel applyRankFilter(Channel channel,
 int radius,
 int filterType)
                               throws OperationFailedException

Applies a 2D rank-filter to each slice independently of a Channel.

Parameters:

channel - the channel to apply the filter to

radius - the radius of the filter

filterType - the type of rank filter to apply

Returns:

the filtered channel

Throws:

OperationFailedException - if channel contains an unsupported data-type

processEachSlice

public static void processEachSlice(Channel channel,
 Consumer<ij.process.ImageProcessor> consumer)
                             throws ImageJConversionException

Applies a Consumer to each slice independently of a Channel.

The slice is exposed as a ImageProcessor.

Parameters:

channel - the channel whose slices will be processed

consumer - successively applied to the ImageProcessor derived from each slice

Throws:

ImageJConversionException - if the voxels are neither unsigned byte nor unsigned short (the only two supported types)

processEachSlice

public static void processEachSlice(BinaryVoxels<UnsignedByteBuffer> voxels,
 Consumer<ij.process.ImageProcessor> consumer)

Applies a Consumer to each slice independently of a BinaryVoxels with UnsignedByteBuffer.

The slice is exposed as a ImageProcessor.

Parameters:

voxels - the voxels whose slices will be processed

consumer - successively applied to the ImageProcessor derived from each slice
