This research proposes and implements a novel approach that integrates region and edge
information for segmenting 2D Computed Tomography Image sequence. Subsequent to
operation by Gaussian Filter and Edge Detection, the seed value is then calculated by
transforming the image from spatial domain to frequency domain. The region is then grown
from the seed value by appending each pixel into its region at successive iterations. The
speed is increased by parallel region growing process. This approach is fully automatic and …
