Tech/Engineering - Patents / (in a patent) TRANSFORMATION OF 3-D OBJECT SEGMENTATION IN 3-D MEDICAL IMAGE
English term or phrase: a multi-scale Laplacian-of Gaussian filter
wherein the means for obtaining the scale estimation of the object is configured to:
obtain a scale estimation of the object in three dimensions;
obtain a further scale estimation by applying a multi-scale Laplacian-of Gaussian filter with a one dimensional kernel in each of the three dimensions.

a Laplacian filter (second derivative filter) is applied to the Gaussian-smoothed image.

In the preferred embodiments, a Laplacian-of-Gaussian (LoG) filter is used for estimating the scale of the lymph node.
