Estimation of gaussian noise in noisy image using MATLAB
In digital images, the gaussian noise is a type of noise that follows a normal or Gaussian distribution. In a digital image, the gaussian noise is visualized as a random variation in pixel intensities. The estimation of gaussian noise is one of the important tasks in digital image processing utilized to perform various operations such as denoising, image restoration, and more. Methods of Estimating Gaussian Noise in Digital Image We can estimate the Gaussian noise in a digital image using various methods. The following are some commonly used methods for estimating the gaussian noise. Standard Deviation Method Histogram Analysis ...
Read MoreDenoising techniques in digital image processing using MATLAB
In digital image processing, denoising is a process of reducing or removing the unwanted noise from a digital image. The primary objective of this process is to enhance the visual quality of an image. Before discussing the different denoising techniques in digital image processing, let us first get an overview of the basics of denoising. What is Denoising in Digital Image Processing? In a digital image, any kind of variation that is unwanted is termed as noise. Noise in a digital image can occur due to different reasons such as environmental conditions, hardware malfunctioning, transmission errors, etc. The process of ...
Read MoreTypes of Integrated Circuits (ICs)
In this article, we will discuss different types of ICs (Integrated Circuits) in electronics. As we know, the integrated circuits (ICs) are one of the crucial parts of all electronic devices and systems. Without ICs, most of the hi tech electronic devices and gadgets that we use would cease to exist. Integrated circuits made the electronic devices and systems so small that they became an integral part of every field of human life. Therefore, integrated circuits or ICs are entirely responsible for miniaturization of electronic devices and circuits. Before discussing different types of ICs, let us first understand a ...
Read MoreRealization of a logic function in SOP form using NAND gate
SOP Form SOP form stands for Sum of Products form. SOP form is one in which a Boolean expression is expressed as a sum of product terms. For example, $$\mathrm{\mathit{f}\lgroup A, B, C\rgroup=AB+ABC+B\overline{C}}$$ This is a Boolean function expressed in SOP (Sum of Products) form. NAND Gate The NAND Gate is a type of universal logic gate. It is a logic gate one that can be used to realize any kind of logical function or any other type of logic gate. A NAND gate is basically a combination of two basic logic gates namely AND gate and NOT gate, i.e. ...
Read MoreRadix Conversion in Digital Electronics
In positional number systems, the radix is the total number of unique digits that are used to represent numbers in that number system. Radix is also called Base. For example, in decimal number system, we use total ten digits from 0 to 9 (i.e. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9) to represent any decimal number. Therefore, for the decimal number system, the radix or base is ten (10). Although we can easily convert a given number from one radix (i.e. number system) to any other radix (number system) by using radix conversion protocols. In this article, ...
Read MoreElectronic Logic Conventions
Electronic logic conventions are the sets of rules followed while designing a digital logic system or device. These conventions are adopted due to their different characteristics observed by several experiments. The use of electronic logic conventions, makes the implementation process of a digit system easy and smooth. Also, a standardization is achieved in the design. This tutorial is entirely meant for explaining different electronic logic conventions used in digital system implementations. As we know, the digital systems are implemented in binary number system due to some technical and economic reasons. The binary number system follows Boolean’s rules to perform arithmetic ...
Read MoreConverting SSOP to SPOS Form
A Boolean function can be expressed into two forms namely, Sum of Products (SOP) Form Product of Sums (SOP) Form The SOP (Sum of Products) form is one in which the Boolean function is expressed as the sum of product terms, while in the POS (Product of Sums) form, the Boolean function is expressed as the product of sum terms of the function. But, in the SOP and POS form, each term of the function may not contain all the variables. For example, consider a Boolean function in three variables, $$\mathrm{\mathit{f}\lgroup A, B, C\rgroup=A\overline{B}+\overline{B}C}$$ This is the ...
Read MoreConversion between Canonical Forms
When a logical expression or Boolean function is expressed as a sum of minterms or as a product of maxterms, then it is called the canonical form of the expression or function. A canonical form of the Boolean expression is also known as standards form, i.e. Standard Sum of Products (SSOP) Form and Standard Product of Sums (SPOS) Form. The canonical form of a Boolean function involves minterms and maxterms. A minterm is a product term which contains all the variables of the Boolean function either in complemented or un-complemented form. A maxterm is a sum term which ...
Read MoreDifference between Electric Circuit and Magnetic Circuit
A circuit is a type of network having a closed path for the flow of either electric current or magnetic flux. A circuit mainly consists of three major parts viz. source, path or conductor and load. In simple words, the term circuit can be used to represent any fixed path through which electricity, data, single or magnetic flux can flow.Depending on the type of quantity (electric current or magnetic flux), the circuits can be of two types as −Electric circuitMagnetic circuitIn this article, we are going to see the differences between electric circuit and magnetic circuit. Also, we have added ...
Read MoreHow to Add a ButtonGroup in MATLAB?
In MATLAB, we can create different types of graphical user interface (GUI) components like Edit Fields, Hyperlinks, Buttons, and more. In this tutorial, we shall confine our attention to add a ButtonGroup in MATLAB. What is a ButtonGroup in MATLAB? MATLAB is an environment that provides an easy way of creating GUI applications without proper knowledge of computer programming. In MATLAB, there is a graphical user interface (GUI) component namely, ButtonGroup, which allows us to create a group of radio buttons or option buttons. One can select only one radio button within the group at a time. This GUI component ...
