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 library defines basic operation on polynomials, and contains also 3 different roots (zeroes)-finding methods that can handle quite large polynomials (>1000 coefs)
Implemented in ANSI C++ Templates. Handles all real and complex floating point types. Html doc is included.
This section describes the development and extension of a basic power flow program in Matlab. To the extent feasible, complex vector operations are used, even for the calculation of the Jacobian matrix .
The emphasis of this book is on real-time application of Synopsys tools, used
to combat various problems seen at VDSM geometries. Readers will be
exposed to an effective design methodology for handling complex, submicron
ASIC designs. Significance is placed on HDL coding styles,
synthesis and optimization, dynamic simulation, formal verification, DFT
scan insertion, links to layout, physical synthesis, and static timing analysis.
At each step, problems related to each phase of the design flow are identified,
with solutions and work-around described in detail. In addition, crucial issues
related to layout, which includes clock tree synthesis and back-end
integration (links to layout) are also discussed at length. Furthermore, the
book contains in-depth discussions on the basics of Synopsys technology
libraries and HDL coding styles, targeted towards optimal synthesis solution.
Besides enhanced looks and advanced features, one of the best things about Swing is its pluggable look and feel (PLAF). PLAF architecture allows seamless changes in the appearance of an application and the way an application interacts with the user. However, designing and developing a PLAF is much more exhaustive and complex. On the other hand, themes provide a simple alternative to change look and feel of the swing application. Themes are easier to implement and they enhance the visual appeal of the application UI using the default Java look and feel.
Theme mechanism allows a developer to easily specify the default colors, fonts and icons used by the look and feel (L&F). It allows developers to write their own themes giving them a choice to show their application GUI the way they want it, rather than depending on the defaults provided by the system.
Introduction to the RTX51, a multitasking real-time operating system for the 8051 family. RTX51
simplifies system and software design of complex and time-critical projects.
This paper describes a bus mastering implementation of the PCI Express protocol using a Xilinx FPGA. While the theoretical peak performance of PCI Express is quite high, attaining that performance is a complex endeavor on top of an already complex protocol. The implementation is described and its performance is analyzed. Source code is offered for free download via the web.
Quartz is a full-featured, open source job scheduling system that can be integrated with, or used along side virtually any J2EE or J2SE application - from the smallest stand-alone application to the largest e-commerce system. Quartz can be used to create simple or complex schedules for executing tens, hundreds, or even tens-of-thousands of jobs jobs whose tasks are defined as standard Java components or EJBs. The Quartz Scheduler includes many enterprise-class features, such as JTA transactions and clustering.
