Method Details

deconvolve

public static ImageOp deconvolve(ColorDeconvolutionStains stains)

Apply the (fixed) color deconvolution stains to an image. The input must be a 3-channel image, with values in the range 0-255.

Parameters:

stains -

Returns:

extract

public static ImageOp extract(int... channels)

Extract or rearrange channels by index.

Parameters:

channels -

Returns:

repeat

public static ImageOp repeat(int numRepeats)

Repeat the channels a specified number of times. This is useful when wishing to apply arithmetic between a single channel and a multi-channel image.

Parameters:

numRepeats -

Returns:

sum

public static ImageOp sum()

Add all channels together, to give a single-channel output.

Returns:

mean

public static ImageOp mean()

Average all channels together using the mean, to give a single-channel output.

Returns:

minimum

public static ImageOp minimum()

Calculate the minimum value along all channels, to give a single-channel output.

Returns:

maximum

public static ImageOp maximum()

Calculate the maximum value along all channels, to give a single-channel output.

Returns:
