-Then, we can get an approximation of <code>x<sub>0</sub></code> by using the one-step estimate, The estimated variance will be computed along with the noise estimate, so we can now compute <code>x<sub>T</sub></code> by using the formula above and obtain the image estimate for the next step. Below are some visualizations for the iterative denoising process:
