Video painting with space-time-varying style parameters

Area of Science:

• Computer Graphics
• Digital Art
• Image Processing

Background:

• Traditional painterly rendering systems often apply a single, fixed style across entire videos.
• This lack of adaptable stylization limits artistic control over object emphasis and abstraction.
• Existing methods typically assume continuous brush stroke orientation, neglecting object boundaries.

Purpose of the Study:

• To develop an object-based painterly rendering system for videos.
• To enable space-time-varying style parameters for enhanced artistic control.
• To allow for dynamic emphasis, de-emphasis, and abstraction of objects within video scenes.

Main Methods:

• The system identifies and segments objects within video frames.
• It utilizes object spatial information to define localized style parameters.
• Brush stroke orientation and style parameters are adapted based on object properties and temporal coherence.

Main Results:

• The proposed system achieves coherent, space-time-varying stylization.
• It provides greater artistic freedom in controlling object appearance and emphasis.
• Demonstrates temporally coherent variations in contrast and abstraction for individual objects.

Conclusions:

• Object-based painterly rendering significantly enhances artistic control in video stylization.
• Space-time-varying parameters allow for nuanced and dynamic artistic expression.
• The approach offers a novel method for achieving sophisticated painterly effects in videos.
