Class PixelProcessor<S,T,U>

java.lang.Object

qupath.lib.experimental.pixels.PixelProcessor<S,T,U>

Type Parameters:

S - The type of image to process

T - The type of mask to use; often the same as S

U - The type of output to generate

public class PixelProcessor<S,T,U>
extends Object

A class for tiled image processing.

The aim of this class is to make it easy to write pixel-based processing algorithms using a variety of different image representations, and also to run these in parallel.

There are four main components:

• An ImageSupplier that provides the image data
• A MaskSupplier that can generate binary masks that correspond to the image
• A Processor that processes the image data
• An OutputHandler that handles the output of the Processor

The idea is that the Processor is the only component that needs to be written for a specific task... and it is usually the fun bit to work on.

The other components are often very tedious to write and hard to get working correctly; also, there is much overlap in the functionality required for different tasks. For these reasons, we provide several default implementations here, written to support different image representations.

Since:

v0.5.0
