GIF stands for Graphics Interchange Format. It is a type of image file which is a raster graphics file format, specially used in web and networking applications. The important characteristic of the GIF image format is that it can support both static and animated objects within the image. In this tutorial, I will explain how you can create an animated GIF image using MATLAB. As we know, MATLAB is an efficient tool to perform various scientific and engineering tasks such as image processing, simulation, etc. We can utilize MATLAB to create animated GIF images. What is a GIF Image? A ... Read More

In digital image processing, histogram equalization is a process of enhancing the contrast and improve the visual quality of an image. We can perform histogram equalization using digital tools like MATLAB. This tutorial is meant for explaining the histogram equalization in digital image processing by using MATLAB. But before that let us get a basic overview about histogram equalization What is Histogram Equalization? As mentioned above, histogram equalization is a technique of improving the contrast and visual quality of a digital image. Histogram equalization redistributes the values of pixel intensities throughout the image more uniformly. Overall, histogram equalization is a ... Read More

In digital image processing, the technique which is used to highlight the borders/boundaries of object withing a digital image is referred to as edge detection. We can use MATLAB to perform this operation. For this, there are several different built-in functions and operators are defined in the MATLAB library. In this tutorial, I will explain three such operators namely, "Prewitt Operator", "Scharr Operator", and "Sobel Operator". All these three operators are commonly used gradient-based edge detection operators available in the MATLAB library. Before going to discuss these operators for edge detection, let us first get a brief overview of ... Read More

In digital image processing, edge detection is a process used to identify the boundaries of objects within a digital image. We have various image processing techniques to detect edges in an image, but in this tutorial, we will learn the edge detection using first derivative operator in MATLAB. What is Edge Detection in MATLAB? MATLAB is an efficient tool to perform complex image processing tasks. One such task is the edge detection, which is nothing but a process of detecting boundaries of objects in an image. In an image, an edge of an object is typically the region where ... Read More

MATLAB is a high−level programming language used to perform engineering and scientific operations such as system design and analysis, matrix manipulation, data interpretation, image processing, app development, and more. MATLAB provides several methods to write reusable codes that can be used to perform repeated tasks. One such code in MATLAB is a function. In this tutorial, I will explain how to create functions in a file in MATLAB. But before that let’s have a look into some basic concepts related to MATLAB functions. What is a Function in MATLAB? In MATLAB, a function is a code or command or ... Read More

In MATLAB, there are class constructor methods which are used to create an instance of a class. Class constructor methods are basically special functions within a class that are used to create and initialize the objects of the class, these class constructor methods are called automatically when we create a new object in the class. In this tutorial, I will explain class constructor methods in MATLAB in detail. What is the Purpose of Class Constructor Methods? As mentioned above, a class constructor method in MATLAB is a special function which is used to create an instance of a class. In ... Read More

In MATLAB, "linear filtering" is a technique used to apply a linear filter to a digital image. The fundamental principle behind the working of linear filtering is convolution. This article is meant for explaining the concept of linear filtering and how to perform linear filtering without using the "imfilter" function in MATLAB. What is Linear Filtering? In digital image processing, the process of applying a linear filter (also called convolution kernel) to a digital image is called linear filtering. The working of linear filtering is based on the concept of convolution. In the process of linear filtering, a convolution ... Read More

MATLAB provides various built-in functions to reverse a string of text. In this tutorial, I am going to explain all the commonly used methods to reverse a string in MATLAB. Reverse a String Using "reverse" Function in MATLAB There is a built-in function "reverse" in MATLAB that we can use to reverse a string. Syntax reversed_string = reverse(string); The steps involved in reversing a string using the "reverse" function are given below − Step (1) − Create a string of text. Step (2) − Call the "reverse" function to reverse the string. Step (3) − Display the ... Read More

In MATLAB, there are various methods and functions for reversing a given number. In this tutorial, I will explain all these methods one-by-one with the help of examples. Reverse a Number Using "fliplr" Function in MATLAB The "fliplr" is a built-in function in MATLAB that we can use to reverse a given number. Syntax reversed_num = fliplr(number); Here, the "number" must be a string. Here are the steps involved in reversing a given number using the "fliplr" function in MATLAB. Step (1) − Input the number. Step (2) − Convert the input number to a string. For ... Read More

MATLAB provides various methods and functions to remove spaces in a string. In this tutorial, we will cover the commonly used methods for removing extra spaces in a string. So, let’s start.
