sketchkit.ordering.orderer module

class sketchkit.ordering.orderer.Orderer(method: str = 'LineDrawer', device: str = 'cuda')

Bases: object

Main interface for sketch ordering. Determines the stroke drawing sequence for a static sketch.

method

The ordering method instance (e.g., LineDrawer or Fu).

static create(method: Literal['LineDrawer'], device: str = 'cuda') → LineDrawer

static create(method: Literal['Fu'], device: str = 'cpu') → Orderer

Create an instance of the specified ordering method.

Parameters:

• method – Backend name. Supported values are “Fu”, “LineDrawer” (case-sensitive).

• device – Device to use for computation. For Fu, “cpu” is sufficient. For LineDrawer, “cuda” is recommended.

Returns:

An instance of the selected ordering method.

Raises:

ValueError – If an unknown method is specified.

run(*args, **kwargs) → Sketch

Run the ordering process using the selected method.

Parameters:

• *args – Arguments passed to the selected method’s run method.

• **kwargs – Keyword arguments passed to the selected method’s run method.

• method (For LineDrawer) – sketch: Sketch object containing the static sketch to animate.

• method – img: numpy array of the sketch image (grayscale). ref_video_path: path to the reference video file.

Returns:

A Sketch object with ordered paths, where the order of paths corresponds to the drawing sequence.

Return type:

Sketch

sketchkit.ordering.Fu

alias of AnimatedDrawer

class sketchkit.ordering.LineDrawer(method='CNNVE', device='cpu')

Bases: Orderer

Implementation of LineDrawer: Stroke-Level Process Reconstruction of Complex Line Art Based on Human Perception.

This method uses a reference video to recover the drawing order of a vector sketch by matching static vector strokes to the video frames where they first appear.

run(img: ndarray, ref_video_path: str) → Sketch

Run LineDrawer to determine the drawing order using the reference video.

Parameters:

• img – numpy array of the sketch image (grayscale).

• ref_video_path – Path to the reference video file.

Returns:

A Sketch object with ordered paths, where the order of paths corresponds to the drawing sequence.

Return type:

Sketch
