What is InvSR?
InvSR is an innovative approach to image super-resolution that leverages diffusion inversion techniques on the SD-Turbo model. It stands out for its ability to perform arbitrary-step image upscaling, offering a flexible solution for enhancing image resolution.
Implementation Details
The model implements a sophisticated noise estimation network trained specifically for SD-Turbo, with the primary checkpoint being noise_predictor_sd_turbo_v5.pth. The implementation utilizes a tiled operation approach for generating high-resolution images, though this can impact processing time.
