Sketch Video Synthesis

Sketch Video Synthesis: A Framework for Dynamic Vector Graphics

Sketch Video Synthesis is an innovative framework designed to generate animated vector graphics from video input. By leveraging the properties of Bezier curves, this system creates smooth and expressive motion traces that maintain temporal consistency across frames. The approach employs advanced loss functions, including semantic preservation and a novel continuity metric, to optimize curve positioning. This enables the creation of impressionistic-style video sketches while preserving spatial and temporal coherence.

Applications

The framework offers versatile applications in various creative domains:

• Video Editing: Transform live-action videos into animated sketch styles for artistic expression or visual enhancement.
• Digital Art: Generate dynamic vector illustrations from source material, such as dance performances or sports events.
• Interactive Design: Create layered animations where strokes can be resized, recolored, and composited over original video backgrounds.

Key Features

The system provides robust tools for creative expression:

• Dynamic Sketch Generation: Automatically generates fluid motion traces from input video sequences.
• Flexible Editing Capabilities: Adjust line thickness, color schemes, and layering to achieve desired artistic effects.
• SVG Rendering Support: Outputs scalable vector graphics that maintain quality across different display resolutions.

Technical Overview

The core technology behind Sketch Video Synthesis involves:

• Bezier Curve Optimization: Utilizes parametric curves to model smooth motion paths between video frames.
• Semantic Loss Function: Ensures that key visual elements are preserved across transformations while allowing artistic interpretation.
• <strong(Temporal Consistency:</strong) Maintains coherent movement patterns over time, ensuring natural-looking animations.

Implementation Highlights

The system supports several advanced features:

• Real-time preview of generated sketches
• Customizable stroke properties
• Layer management for complex compositions
• Export options for various digital formats

Target Audience

This tool is designed for:

• Content Creators: Enhance video content with unique animated overlays.
• Artists and Designers: Generate dynamic vector art from source material.
• Hobbyists: Experiment with creative video transformations without technical expertise.

Use Cases

Some notable applications include:

• Converting sports videos (e.g., snowboarding) into animated sketch styles for visual interest.
• Transforming dance performances into fluid, artistic animations.
• Add dynamic strokes and overlays to live footage for creative video projects.

In summary, Sketch Video Synthesis offers a powerful yet flexible approach to generating animated vector graphics from video input. Its combination of advanced curve modeling, semantic preservation, and customizable rendering options makes it a valuable tool for artists, designers, and content creators alike.
