PCA / SVD Denoise

Apply a PCA/SVD-style denoising workflow to an image.

Learn how to use WaveRay for PCA / SVD Denoise with real, manually matched screenshots. This tutorial covers setup, execution, result interpretation and practical checks.

What this tutorial covers

Apply a PCA/SVD-style denoising workflow to an image.

Before you start：You need access to the product and should ideally follow the tutorial using your own real parameters or data. The screenshots below were manually rematched to avoid the image/topic mismatches seen in the previous version.
PCA / SVD Denoise - Open the relevant module and confirm the starting state.

Step-by-step workflow

1Open the module

Open the PCA / SVD Denoise module. Confirm that the visible page really matches the tutorial topic before changing any settings.

2Configure the input

Prepare and check the input image and denoising-related parameters.

3Run and watch the status

Import the image, run the denoising process and inspect the processed output. Watch the visible status, plot or log area while the workflow is running.

4Inspect the result

Pay special attention to the denoised result and its visual comparison.

5Verify and iterate

Over-aggressive denoising can remove useful detail, so compare smoothness against edge preservation. Change one meaningful parameter and rerun so you can verify whether the output changes in the expected direction.

How to read the result

  • The main output of this workflow is the denoised result and its visual comparison.
  • Read the result together with the exact inputs used for the run; a screenshot alone rarely tells the whole story.
  • Over-aggressive denoising can remove useful detail, so compare smoothness against edge preservation.

Troubleshooting & practical tips

  • If nothing changes, first confirm that the correct module is open.
  • If the output looks unrealistic, check units, field mapping and input scale first.
  • For comparisons, change one key parameter at a time whenever possible.
