feature-preserving diffusion of gradient information. It was originally introduced by Xu and Prince to drive snakes‚ or active contours‚ towards edges of interest in image segmentation. But GVF is also used for detection of tubular structures and skeletonization. In this post I present a simple Matlab implementation of GVF for 3D images which I made because I could not find any online. The implementation is a simple extension of Xu and Prince original 2D implementation found at their website. GVF

Natural Language Processing Natural language processing (NLP) is a field of computer science‚ artificial intelligence‚ and linguistics concerned with the interactions between computers and human (natural) languages. As such‚ NLP is related to the area of human–computer interaction. Many challenges in NLP involve natural language understanding -- that is‚ enabling computers to derive meaning from human or natural language input. An automated online assistant providing customer

The Central Processing Unit Microprocessors‚ also called central processing units (CPUs)‚ are frequently described as the "brains" of a computer‚ because they act as the central control for the processing of data in personal computers (PCs) and other computers. Chipsets perform logic functions in computers based on Intel processors. Motherboards combine Intel microprocessors and chipsets to form the basic subsystem of a PC. Because it’s part of every one of your computer’s functions‚ it

What is an OLTP System? Online Transaction Processing (OLTP) systems are one of the most common data processing systems in today’s enterprises. Classical examples of OLTP systems are order entry‚ retail sales‚ and financial transaction systems. OLTP systems are primarily characterized through a specific data usage that is different from data warehousing environments‚ yet some of the characteristics‚ such as having large volumes of data and lifecycle-related data usage and importance‚ are identical

Online Transaction Processing (OLTP) The following is partially extracted from GC33-0754-00. 1. Overview An application is a particular use to which a data processing system is put‚ for example‚ a payroll application or an order entry application. Commercial applications typically process many similar items‚ for example‚ an order in an order processing system‚ a seat reservation in an airline booking system‚ or a credit query in a credit control system. The processing of one of these items is a

Humans are processors of information and can process things in different ways. Serial and parallel processing are two ways. Serial is the way the mind processes things sequentially‚ one thing at a time. For example‚ when reading a book‚ you cannot process all the words in one glance or even reading the sentences of this forum. Instead‚ you have read in a sequence‚ from left to right and process each word. Parallel is when the mind processes things simultaneously‚ more than one thing at a time (Schmidt

Theories of Staining Techniques Staining bacteria with different dyes via staining techniques‚ allows in distinguishing the microorganism from its backgrounds. Also‚ helps in studying different internal structures such as vacuoles‚ cell walls and spores in details (Seeley and others 1991). Some staining techniques such as Gram staining‚ endospore stain and capsule stain are some of the theories of stains used in bacteriology today. Also‚ these staining procedures help in determining properties

Premium Image processing Function
A CPU processor or central processing unit controls the functions of most electronic products. The CPU accepts the input data‚ processes the information and sends it to the component that is in charge of executing the action. CPUs are also known as microprocessors and are at the center of any computer system. Although CPUs are most often thought of as a computer chip‚ they can also be found in many other electronic devices including cell phones‚ hand held devices‚ microwaves‚ television sets and toys
