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 red, green, and blue lights. Therefore, in the RGB color space, each pixel in a digital image composed of three−color channels namely red, green, and blue. On the other hand, YIQ is another color space that is mainly employed in analog video or NTSC systems. YIQ stands for Luminance (Y), ... 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 specific operation. A function basically eliminates the need of writing instructions repeatedly. Also, it encapsulates all the technical information of the operations and provides a short and easy to use executable code to perform the operation. Functions has several advantages such as easy implementation, reusability, easy maintenance, etc. Components of ... 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 create a dropdown menu. This function can have different syntaxes to create different types of dropdown menu. The most commonly used types of dropdown menu are as follows: Dropdown menu without any parameters Dropdown menu with a specific parent container Dropdown menu with a specific parent container and properties ...

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 of circles in a digital image in MATLAB is explained below: Step (1)− Read the input image. Step (2)− Convert the input image to grayscale, if necessary. Step (3)− Create a circular or disk−shaped structuring element of a specific size for erosion of the image. Step (4)− Erode the grayscale ... 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 RGB color space, each pixel in a digital image composed of three−color channels namely red, green, and blue. On the other hand, HSI stands for Hue Saturation and Intensity. It is also called HSV, where HSV stands for Hue Saturation Value. An image represented based on the color model of ... Read More
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 MATLAB application. The step−by−step procedure to create a GUI button in a MATLAB app is explained below. Steps to Create GUI Button in MATLAB App We can follow the following steps to create a GUI button in a MATLAB application: Step(1)– Open the MATLAB command window. Step(2)– Launch the MATLAB ...

Python is a widely used programming language used for different purposes such as Web Development, Data Science, Machine Learning and to perform different operations with automations. In this article we will learn about different ways to convert a 3D list into 2D list. Let's first have a look how does both the types of list look like: - 3D List Three_dimensional_list = [ [['Sam', 'Tom'], ['Miller', 'David']], [['Rocky', 'Tyler'], ['Mason', 'Petrick']], [['Stefen', 'Damon'], ['Matt', 'Jeremy']] ] # This is the basic structure of a three dimensional list 2D ...

Python is a widely used programming language used for different purposes all over the world like web development, data science, machine learning and to perform various processes with automation. The output of Boolean is in the form of True & False. So, if we want to convert it into integer, we can represent true as 1 and false as 0. In this article we will learn about the different ways to convert Boolean values into Integer. Different Ways to Convert Boolean Value to Integer Integer Function In this method we will run the integer function along ... Read More
One can refer this article to learn about different methods to concatenate Boolean to string. All the different methods can be used in different cases. Different Methods to Concatenate Boolean to String String Function Let's take an example to understand it in a proper manner: - Example # Case 1 value_of_boolean = True # The value of Boolean is given as input to the function final_string = "The value of the boolean will be displayed as: " + str(value_of_boolean) # The Boolean is converted into string with the help of str function print(final_string) # ...
