Invsr
Overview :
InvSR is a diffusion inversion-based image super-resolution technology that leverages the rich image priors from large pre-trained diffusion models to enhance super-resolution performance. This technology constructs intermediate states of the diffusion model through a partial noise prediction strategy, serving as starting sampling points, while employing a deep noise predictor to estimate an optimal noise map, thus initializing sampling during the forward diffusion process to generate high-resolution results. InvSR supports any number of sampling steps, ranging from one to five, and even demonstrates performance superior to or comparable with existing state-of-the-art methods when using just a single sampling step.
Target Users :
The target audience for InvSR primarily includes researchers and developers in the field of image processing, particularly those specialized in image super-resolution reconstruction. Given that InvSR offers high-quality image enhancement effects, it is also suitable for photographers, designers, and any average user needing to improve image quality.
Use Cases
Using InvSR to repair and enhance old photographs.
Enhancing the clarity of surveillance images using InvSR in the field of monitoring.
Utilizing InvSR to improve the resolution of MRI or CT scan images in medical image analysis.
