Images Encoded as Gaussian Mixture Models

Comparison of different upscaling methods

2D gaussian mixture model was fitted to images with a similar method as proposed by GaussianImage. The decoding or rendering resolution can be changed dynamically and upscaling methods can be compared. Our method spline utilizes analytical gradients and is able to upscale images with higher quality. The images are decoded / rendered in real time with WebGPU.
