....our implementation, seeds are defined as foreground regions. Direct evaluation of the signed distance function or a fast marching method may be used to generate . In order to obtain the pixel memberships of different regions from , a modified region labelling algorithm is used (see chapter 8 of [19]) This is step 01 in Section 4. Two modifications are made. The first, is to label foreground regions with positive labels and background regions with negative labels , and the second is to label as foreground those negative pixels immediately adjacent to foreground regions. The first, ....

Original images The entire set of original images from the Exeter PANN database is used for the analysis. Step 2. Convert to .PGM Using the convert command in Linux, each original colour image is converted to a 256 greyscale Portable Grey Map ( pgm) format of size 512x512 pixels. ....

....one can reduce the total asymptotic running time to O(m) see e.g. CKPT92] but the results depend on the random initial splitting which leads to variability in the final clustering. Other algorithms also exist which can also lead to high quality results (e.g. k nearest neighbor or k means) GJJ96] but most suffer from high cost (e.g. nearest neighbor) or depend critically on a good starting point which is often chosen randomly (e.g. k means) Birch [ZRL96] incrementally builds a tree during a single pass over the data, and sweeping over the data in a different order could change the ....

....speed of a circle of radius r # # # ### passing through the same point, i.e. q r 2 # # # ### # r 0 # # # ### # 2 = q r 2 # # # ### 0 2 . If we define P to be the perimeter of the shape and A to be its area, then the dimensionless quantity C =4#A=P 2 is a measure of circularity [8] that varies from 0 to 1. For example, circles achieve a maximum circularity of unity. Squares have circularity equal to 0.7854 and equilateral triangles have circularity 0.6046. An important feature of this measure is its scale invariance: scaling of the shape does not change its circularity ....

....and relatively low computational overhead. Keywords Genetic algorithm; neural network; classification; ionosphere 1 Introduction Feature selection is the process of selecting an optimum subset of features from the enormous set of potentially useful features available in a given problem domain [2]. The optimum subset of features which is the aim of the feature extraction algorithm can be defined as the subset that performs the best under some classification system [4] where performs the best is often interpreted as giving the lowest classification error. The feature selection ....
