SKETCH ANIMATION FROM TEXT: METHODS, CONTROL AND MOBILE DEPLOYMENT

Abstract. This article explores existing approaches and methods for generating animated sketch videos from text descriptions, focusing on the feasibility of on-device deployment and controlled generation mechanisms. The research aims to review and analyze current methods, identify critical challenges, and outline pathways toward fully autonomous on-device sketch animation systems. The key contributions include: a structured taxonomy of methods based on input type, control mechanism, and architecture; a critical analysis of their suitability for mobile deployment; the identification of key technical barriers and future research directions. The study analyzes publications from 2023–2025, covering diffusion-based approaches, controlled video generation frameworks, and mobile optimization techniques, including quantization, pruning, and knowledge distillation. The findings indicate that while current methods achieve high generation quality, they require significant computational resources that exceed mobile device capabilities by a factor of 10–100. Modern mobile neural processing units (NPUs) combined with model compression techniques offer promising paths for acceleration, yet substantial architectural innovations are still needed. Key research gaps include temporal consistency in lightweight models, trade-offs between fine-grained control and efficiency, and multi-object animation limitations.

Keywords: sketch animation, text-to-video generation, video diffusion models, mobile deployment, controllable generation, on-device inference, model compression, NPU.
