  The multifaceted nature of human perception and comprehension indicates that,
when we think, our body can naturally take any combination of senses, a.k.a.,
modalities and form a beautiful picture in our brain. For example, when we see
a cattery and simultaneously perceive the cat's purring sound, our brain can
construct a picture of a cat in the cattery. Intuitively, generative AI models
should hold the versatility of humans and be capable of generating images from
any combination of modalities efficiently and collaboratively. This paper
presents ImgAny, a novel end-to-end multi-modal generative model that can mimic
human reasoning and generate high-quality images. Our method serves as the
first attempt in its capacity of efficiently and flexibly taking any
combination of seven modalities, ranging from language, audio to vision
modalities, including image, point cloud, thermal, depth, and event data. Our
key idea is inspired by human-level cognitive processes and involves the
integration and harmonization of multiple input modalities at both the entity
and attribute levels without specific tuning across modalities. Accordingly,
our method brings two novel training-free technical branches: 1) Entity Fusion
Branch ensures the coherence between inputs and outputs. It extracts entity
features from the multi-modal representations powered by our specially
constructed entity knowledge graph; 2) Attribute Fusion Branch adeptly
preserves and processes the attributes. It efficiently amalgamates distinct
attributes from diverse input modalities via our proposed attribute knowledge
graph. Lastly, the entity and attribute features are adaptively fused as the
conditional inputs to the pre-trained Stable Diffusion model for image
generation. Extensive experiments under diverse modality combinations
demonstrate its exceptional capability for visual content creation.
