Digital Image Processing

Image
  Image processing is the process of manipulating digital images. See a list of image processing techniques, including image enhancement, restoration, & others. Digital image processing is the use of a digital computer to process digital images through an algorithm. As a subcategory or field of digital signal processing, digital image processing has many advantages over analog image processing. It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and distortion during processing. Since images are defined over two dimensions or more, digital image processing may be modeled in the form of multidimensional systems.  The generation and development of digital image processing are mainly affected by three factors: first, the development of computers; second, the development of mathematics (especially the creation and improvement of discrete mathematics theory); and third, the demand for a wide range ...

What is Computational Complexity of an algorithm ?

Image
 An algorithm is a method or procedure for accomplishing a specific task, and which is sufficiently precise and that can be programmed on computer. In Computer Science, it is important to measure efficiency of algorithms before applying them on a large scale i.e., on bulk of data. The quality of an algorithm or shall we say, performance of an algorithm depends on many internal and external factors. Internal Factors specify algorithm's efficiency in terms of : Time required to run Space required to run External Factors affect the algorithm's performance. These include:  Size of the input to the algorithm  Speed of the computer on which it is run Quality of the compiler  Quality of the compiler Since, external factors are controllable to some extent, mainly internal factors are studied and measured in order to determine an algorithm's efficiency or we can say complexity. Complexity of an algorithm is determined by studying and measuring internal factors affecting ...

Learn the difference between BJT and Mosfet

Image
 BJT and MOSFETS are a very widely popular transistors  and are used in most electronic devices to know the difference between them and their applications first we have to know about what are transistors and how these semiconductor devices work. What are semiconductor devices? Semiconductor devices are electronic components that utilize the properties of semiconductor materials to control the flow of electric current. These devices are crucial building blocks in modern electronics and are found in a wide range of applications, including computing, telecommunications, power electronics, and consumer electronics. Some common semiconductor devices include: Diodes, Transistors, Integrated Circuits (ICs), Optoelectronic Devices, Thyristors, MEMS (Micro-Electro-Mechanical Systems) Devices, and many more. What is a transistor? A transistor is a miniature semiconductor that regulates or controls current or voltage flow in addition amplifying and generating these electrical signals and...
