Abstract—In real-world images, inhomogeneity in intensities usually occurs and this makes image
segmentation a difficult task. In this paper, an attempt has been made to segment the images
having different level of intensity variations. The major contribution of the proposed paper is to
extract accurate local intensity information using the Gaussian kernel function. This kernel function
is further used to define two spatially varying fitting functions which utilize the neighborhood
intensity information of each centralized pixel and guided the motion of the contour towards the
desired boundary of objects in the presence of inhomogeneity. Also, multi-resolution wavelet
decomposition is incorporated in the proposed method to deal efficiently with noisy images.
Further, an efficient level set method by preserving the distance function has also been
implemented in this paper in order to perform the comparative analysis with the proposed method.
The whole framework has been tested on 15 images obtained from standard Berkeley and
Weizmann databases. The results confirmed that the proposed method outperforms efficient
level set algorithm method by preserving the distance function in terms of Global consistency
error, Probabilistic Rand Index and Variation of Information.
