AtomoVideo: An Approach to High Fidelity Image-to-Video Generation
Overview of AtomoVideo
AtomoVideo represents a novel framework geared towards image-to-video (I2V) generation that ensures a high degree of fidelity of the video to an input image. The framework leverages multi-granularity image injection to achieve a remarkable balance between motion intensity and temporal consistency. The architecture facilitates long video sequence prediction and supports integration with personalized models for customized video generation. In their comparison against existing methods, AtomoVideo demonstrates superior performance across several metrics.
