Below the Enhance sliders are the heavier filters. They process the full-resolution image: you see a quick quarter-resolution preview first, then the full image a moment later.
Multi-scale enhancement
Splits the image into 8 bands by feature size, from 1–2 pixels up to 128–256 pixels (shown in millimetres when the file has pixel spacing). Each band has its own gain from 0 to 400 %. Turn it On, set Amount, and use Detail curve to lift small detail more than large. Boost the small bands for cracks and fine porosity, or the large bands for liquid levels and thickness changes.
Noise & artefacts
- Guided filter noise reduction: fast and keeps edges well. Good general choice.
- Anisotropic diffusion: smooths along edges rather than across them. Good for grainy images with linear features.
- Noise reduction strength sets how much.
- De-stripe removes regular row or column banding from the detector.
Background
Rolling-ball background removal takes away everything larger than the radius you set (shown in px and mm), leaving the detail. Choose Both, Keep light detail or Keep dark detail.
Deconvolution sharpening
Undoes the system blur using the Richardson–Lucy method. Enter the basic spatial resolution in µm (from your duplex wire IQI reading), then set the number of iterations. Without the basic spatial resolution it does nothing, and the panel reminds you to enter it.
Dual window
Shows two densities at once, such as a thin wall and a thick flange. Turn it On, set the Second level and Second width, and the Blend area. Second window from ROI takes the second window from a box drawn on the other density.
WebGPU or CPU
On browsers with WebGPU (current Chrome, Edge and Safari on most devices), these filters run on the graphics card and take a fraction of a second. Elsewhere they run on the CPU and give the same result, more slowly. The image information panel shows which is in use, and the processing description records it.
