Abstract

Character animation production faces significant efficiency challenges due to labor-intensive keyframe interpolation processes that require extensive manual intervention. This paper presents a novel intelligent keyframe in-betweening technology based on generative adversarial networks (GANs) to automate intermediate frame generation while preserving character consistency and motion quality. The proposed framework incorporates a multi-scale temporal feature extraction mechanism that captures complex motion patterns through residual connections and attention-based aggregation. An improved GAN architecture employs dual-path processing streams combining spatial and temporal information, enhanced with spectral normalization and adaptive instance normalization for stable training dynamics. The character consistency preservation algorithm integrates deep feature matching with geometric constraint enforcement to maintain visual coherence across generated sequences. Experimental validation on a comprehensive dataset of 55,000 animation sequences demonstrates superior performance with SSIM scores reaching 0.923 and temporal consistency measures achieving 0.856, representing substantial improvements over existing methodologies. User studies involving 165 participants confirm practical applicability, with professional animators rating the generated sequences at 4.19/5.00 for overall quality. The technology enables significant productivity gains in animation production workflows, achieving 30-45% cost reductions while maintaining professional quality standards, making high-quality animation more accessible across diverse commercial applications.
