In MATLAB App environment, we can develop a GUI (Graphical User Interface) app without having proper knowledge of coding. Therefore, MATLAB app building allows us to create professional applications without writing code, and just by drag−drop. In this article, we will discuss how to create a GUI button in a ...

In this article, we learn how to change the green background of an image to some other background using MATLAB programming. The concept of changing a green screen background to another background involves the use of a technology called “chroma key”. This technology detects the absolute green color in the ... Read More

In this article, we will explore how to calculate variance in MATLAB. In mathematics, variance is a statistical tool used to measure the degree of dispersion of a set of data points around its average value. It is widely used to quantify the diversity or variability of a set of ... Read More

In this article, we will learn ow to calculate the impulse response of a system in MATLAB. Impulse response is an elementary concept used in analyzing and understanding the behavior of systems for an impulse input. It is mainly used to analyze the linear time invariant systems like digital filters, ... Read More

In this article, we will learn to calculate standard deviation in MATLAB. Standard deviation is a mathematical operation that gives the measure of variation in a set of data points. The standard deviation is used to study the dispersion of data around their average value. If a set of data ... Read More

In this article, we will explore how to calculate moving sum using MATLAB programming. But before that let us have a look into the concept of moving sum. What is Moving Sum? Moving sum is a mathematical operation that allows to calculate the sum of a set of numbers over ... Read More

In this article, we will learn how to convert a YIQ image into an RGB image using MATLAB programming. YIQ is color space used in analog display devices to display color images. It uses three components namely, Y (brightness), I (In−Phase), and Q (Quadrature) to distinguish the image. Here, the ... Read More

In this article, we will explore how to convert a colored image with three channels, i.e. RGB (Red, Green, and Blue) into a gray scale image using MATLAB. An RGB image is a digital image in which each pixel is represented as a combination of intensity of three−color channels, namely ... Read More

In this article, we will explore how to convert an RGB image to a binary image using MATLAB programming. An RGB image is one which is represented by using three color channels namely, Red, Green, and Blue. In the case of an RGB image, the three primary colors, namely red, ... Read More

HSI (also called HSV) and RGB are two different types of color spaces. Where, HSI stands for Hue Saturation and Intensity, (HSV stands for Hue Saturation Value). An image represented based on the color model of HSI is called an HSI image. On the other hand, RGB stands for Red ... Read More
