OTSU Gray-level image segmentation using Otsu s method. Iseg = OTSU(I,n) computes a segmented image (Iseg) containing n classes by means of Otsu s n-thresholding method (Otsu N, A Threshold Selection Method from Gray-Level Histograms, IEEE Trans. Syst. Man Cybern. 9:62-66 1979). Thresholds are computed to maximize a separability criterion of the resultant classes in gray levels. OTSU(I) is equivalent to OTSU(I,2). By default, n=2 and the corresponding Iseg is therefore a binary image. The pixel values for Iseg are [0 1] if n=2, [0 0.5 1] if n=3, [0 0.333 0.666 1] if n=4, ... [Iseg,sep] = OTSU(I,n) returns the value (sep) of the separability criterion within the range [0 1]. Zero is obtained only with images having less than n gray level, whereas one (optimal value) is obtained only with n-valued images.

This is a PSO toolbox implementing Common, Clerc 1", and Trelea types along with an alpha version of tracking changing environments. It can search for min, max, or distance of user developed cost function. Very easy to use and hack with reasonably good documentation (type help for any function and it should tell you what you need) and will take advantage of vectorized cost functions. It uses similar syntax to Matlab s optimization toolbox. Includes a suite of static and dynamic test functions. It also includes a dedicated PSO based neural
