Package com.openinventor.imageviz.engines.imagefiltering.smoothinganddenoising
The Smoothing And Denoising category contains lowpass filters to reduce the contrast and soften the edges of objects in an image.
A lowpass filter lets low frequencies go through but attenuates high frequencies and noise. It reduces contrast but tends also to defocus the image.
For an introduction to image filters, see section Image Filters.
