FrameForge adapts video models for diverse conditional image generation with input-adaptive temporal relations
FrameForge leverages pretrained video diffusion models by dynamically selecting temporal positional embeddings and introducing a latent reasoning state, achieving superior results on subject-driven generation, canny-to-image generation, and image editing benchmarks.
Based on the paper FrameForge: Harnessing Priors of Video Foundation Models for Unified Image Generation by Yijing Lin, Zhendong Mao, Mengqi Huang, Yuxin Wang and 1 other
Challenges in unified conditional image generation and temporal modeling
Conditional image generation requires producing a target image that respects a given visual input and textual guidance, but different tasks impose diverse and varying constraints on how the input relates to the output.
Existing unified models often treat conditions as fixed auxiliary inputs without explicitly modeling how much or in what way the target should differ from the condition, limiting their flexibility across heterogeneous tasks.
Pretrained video models encode visual transformations over time and offer a natural prior for modeling condition-target relations, but prior methods fix the temporal positions of condition and target frames, ignoring the wide variation in their relationships across tasks and samples.
This paper observes that the degree of visual change between condition and target images varies similarly to frame intervals in natural videos, motivating an input-adaptive virtual temporal interval to better capture these relations.
Two complementary aspects arise: how far the target lies from the condition (transformation magnitude) and how the condition transforms into the target (transformation process), both needing explicit modeling for unified generation.
