Introduction to Up−Sampling In digital signal processing, the technique which allows to increase the sampling rate of a signal is termed as up−sampling. For a signal expressed in frequency domain, the up sampling is performed by adding zeros in the frequency domain. In digital signal processing, the up sampling in ... Read More

MATLAB is a scientific programming language that provides different ways of expression information. One of them is 2D discrete data plots. In MATLAB, we can create several different types of 2D discrete data plots to represent data and information graphically. In this article, we will explore different types of 2D ... Read More

In MATLAB, an array is a data structure used to store elements in contiguous memory blocks. A column vector is a one−dimensional array of elements. In a column vector, the elements are arranged column−wise. It is also important to note that MATLAB by default stores arrays in a column wise ... Read More

In MATLAB, a matrix is nothing but an array of rows and columns arranged in a square or rectangular shape. A matrix is basically a two−dimensional array of numbers. MATLAB allows us to create various types of matrices, such as n × n matrix, n × m matrix, column vector, ... Read More

In computer−based image analysis and processing, the image segmentation is an essential task. The image segmentation allows us to extract specific objects or regions from an image. In digital image processing, the most widely used image segmentation technique is the thresholding−based image segmentation. This image segmentation technique works depending on ... Read More

In the field of digital image and video processing, there are two popular color spaces namely RGB and YIQ. Where, RGB stands for Red, Green, and Blue. The RGB color space is widely used for displaying digital images on display screens. This color space utilizes a combination of intensities of ... Read More

In this article, we will learn how to create a function in MATLAB and how to use that function in a MATLAB program to perform an operation. What is a Function in MATLAB? In MATLAB, a function is nothing but a block or set of instructions used to perform a ... Read More

In this article, we will learn how to create a dropdown menu/list in MATLAB. In MATLAB, a dropdown menu is a user interface (UI) component allows users to choose one the multiple options or to type as text. In MATLAB, we have a built−in function named ‘unidropdown’ that allows to ... Read More

In this article, we will learn to implement MATLAB codes to count the number of circles in a digital image. The counting the number of circles in an image is performed by using various image processing techniques like image erosion, circle detection, etc. The step−by−step procedure to count the number ... Read More

In this article, we will discuss how to convert an RGB image into an HSI (HSV) image using MATLAB. The RGB color space is widely used for displaying digital images on display screens. This color space utilizes a combination of intensities of red, green, and blue lights. Therefore, in the ... Read More
