The SSF is a critical component of the StreamDiffusion architecture, designed to enhance real-time interactive generation systems such as those used in the Metaverse, video streaming, and gaming applications. By calculating the cosine similarity between successive input images, the SSF determines the likelihood of processing redundancy based on minimal changes between frames. This approach allows for a dynamic allocation of computational resources, particularly GPU processing power, by pausing unnecessary processing activities. It employs a probabilistic method to decide whether subsequent processing steps, including VAE Encoding, U-Net transformation, and VAE Decoding, should be bypassed, ensuring smoother video generation and preventing the visual perception of "stuck" frames due to excessive processing of near-identical images oai_citation:1,StreamDiffusion: A Pipeline-level Solution for Real-time Interactive Generation - Unite.AI oai_citation:2,[2312.12491] StreamDiffusion: A Pipeline-level Solution for Real-time Interactive Generation.
