Sample text

A graphical document including written text, logos and drawings, only two values are used to denote the obtained foreground and background, respectively. Alternatively, when the information carried on by graylevels are still necessary to further analyze the foreground components, the resulting image will consist of a foreground, whose pixels have the same gray-levels as their homologous pixels in the original image, superimposed on a homogeneous background. A recent survey of about 40 thresholding methods can be found in [1].

This is an old but important topic in many medical applications. The general goal of segmentation is to group the image primitives having similarity together. The image primitives can be low-dimensional such as pixel gray level, texture, or they can be hyper-dimensional such as a composition of many useful features. There are many histogram based image segmentation articles over the past decade. It is difficult to categorize them because the amount of related studies is too large. We however divide them into two groups: parametric [1,2] and nonparametric method [3].

Either only clockwise or only counter-clockwise, because the counter-clockwise order and the clockwise order can be transformed to each other by a 3D rotation. This is called removing the reflection shape [6]. 2 S. Yang et al. Complex Bingham Distribution After having transformed the BAC-triangles onto the x-y plane, we use the complex Bingham distribution to model the shape distribution. This technique provides an elegant framework for the analysis of 2D shape data [6]. , it indicates whether the shape distribution of triangles has the tendency to be uniform.
