Real images are often corrupted by noise from various sources.Bilateral filtering is a nonlinear filter that considers intensity variations as well as spatial closeness in the noise smoothing process.It has been demonstrated to have a better edge-preserving quality than linear filters in certain applications.This paper presents the new edge detection algorithm with the application of a bilateral filter in Gaussian form in Spiral Architecture.Spiral Architecture is a relatively new concept in the area of image representation and offers distinctive advantages.The approach to edge detection is multi-scale.Edge maps of the original image and its successively smoothed versions are used to produce the final edge map.
