Figure 2From: Unsupervised segmentation of noisy electron microscopy images using salient watersheds and region mergingThe Salient Watershed algorithm. A) The original input image. B) Non-local means filter applied to de-noise the image. C) Detecting high-confidence boundary edges. D) Elevating watershed levels where Canny and Pb coincide. E) Final watershed output on the enhanced image. See 3 for full description of each step.Back to article page
