MATLAB is an efficient tool to process and manipulate matrices. We can use it to shuffle the columns in a matrix. For this, MATLAB provides built-in functions that can be used together to shuffle the columns in a matrix. In this tutorial, I will explain how you can randomly shuffle ... Read More

In digital image processing, random pseudo coloring is a technique in which pixels of a grayscale image are assigned a random color. In this tutorial, I am going to explain the process of performing random pseudo coloring in a grayscale image using MATLAB. What is Random Pseudo Coloring in Grayscale ... Read More

In digital image processing, the process of improving visual quality and clarity of a digital image by changing the color intensities is referred to as "contrast enhancement". Contrast enhancement is an important image processing task in various fields such as photography, remote imaging, medical imaging, etc. We can use various ... Read More

As we know, MATLAB is a powerful to perform image processing and signal processing. We can use it to alter different parameters of an image like brightness, contrast, saturation, and more. In this article, I will explain how we can perform contrast enhancement of a color image using MATLAB. What ... Read More

A histogram is nothing but a graphical representation that shows the distribution of a set of data points. The normalization of a histogram is a process of distributing its frequencies over a wide range. Before discussing the implementation of histogram normalization in MATLAB, let us first get an overview of ... Read More

MATLAB is a powerful tool to perform various operations on matrices. In the case of matrices, iterating through elements of a matrix is one of the common operations used to perform various other matrix operations such as finding sum of all elements of a matrix, finding maximum and minimum values ...

As we know, MATLAB is a powerful tool to perform various operations on matrices and arrays. Vector is a type of matrix having only one row or one column. We can determine the inverted version of a vector using MATLAB. For this, MATLAB provides different methods and functions. So, let’s ... Read More

These three types of signals (unit step, sinusoidal, and exponential) are basic signals used in analyzing different types of systems. A unit step signal has a step of magnitude one after a specific time instant. A sinusoidal signal is a type of signal which has either a sine ... Read More

As we know, MATLAB is a powerful tool that can be used to perform various operations on matrices. One such operation is finding the percentage of similarity between two matrices. Finding percentage of similarity between two matrices is crucial in various application such as digital image processing, data analysis, machine ... Read More

A periodic sequence is one which repeats its pattern at regular intervals, whereas an aperiodic sequence is another type of sequence in which there is no regularity in the pattern. We can use MATLAB to generate periodic and aperiodic sequences. Before going to learn about generating periodic and aperiodic sequences ... Read More
