Method Detail

doTransform

protected ImageWritable doTransform(ImageWritable image,
                                    Random random)

Takes an image and executes a pipeline of combined transforms.

Specified by:

doTransform in class BaseImageTransform<org.bytedeco.opencv.opencv_core.Mat>

Parameters:

image - to transform, null == end of stream

random - object to use (or null for deterministic)

Returns:

transformed image

query

public float[] query(float... coordinates)

Description copied from interface: ImageTransform

Transforms the given coordinates using the parameters that were used to transform the last image.

Specified by:

query in interface ImageTransform

Overrides:

query in class BaseImageTransform<org.bytedeco.opencv.opencv_core.Mat>

Parameters:

coordinates - to transforms (x1, y1, x2, y2, ...)

Returns:

transformed coordinates
