Binarization of Digital Images Using Otsu Method in MATLAB
In digital image processing, the process of transforming a color image or a grayscale image into a binary image is referred to as binarization of the image. In a binary image, the image pixels are represented using binary values i.e., 0 and 1, where 0 represents the black pixel and 1 represents the white pixel. Binarization is an efficient technique to simplify the image analysis and it also helps in extracting important characteristics of the image. Process of Binarization of Digital Images The process of binarization of a digital image is based on the use of a threshold value to ...
Read MoreWhat is Edge Analytics in IoT?
Edge analytics is a cutting−edge form of data analysis that takes place at the network's edge, where data is actually produced. Unlike traditional analytics conducted in centralized data centers, edge analytics recognizes the growing significance of the Internet of Things (IoT). With the proliferation of IoT devices generating massive data volumes, it becomes impractical or unfeasible to transmit all this information to a central location for analysis. Edge analytics offers a solution by performing data analysis directly at the edge of the network, enabling enhanced performance, reduced latency, and improved security. In this article, we will discuss more ...
Read MoreImproving Business Decision-Making Using Time Series
Introduction Time series is one of the widely used in machine learning and data science, used to forecast and analyze the data collected with time components. It is a field of intelligence where the data can be forecasted and analyzed with the help of past data collected. In industry, businesses are using the time series analyzed and related methods to improvise their decision-making process. In this article, we will discuss the ways in which the time series can help improve the decision-making process in the industry and how businesses are using the same to enhance their productivity and ...
Read MoreThe Role of Trial and Error in Data Analysis
Introduction Data analysis is an approach in the field of data science and machine learning where the dataset is analyzed well in order to get the relationship between dataset features and get an idea about the behavior of the data and its parameters. In data analysis, trial and error play a major role while developing a machine learning model. It has certain advantages that allow data analysts or data scientists to make the model more reliable and predictive according to the dataset available. In this article, we will discuss the role of trial and error in data analysis, ...
Read MoreUp Sampling in Frequency Domain in MATLAB
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 frequency domain is commonly used to interpolate or expand the bandwidth of a digital signal. In MATLAB, the up−sampling process is completed in the following three phases: Step 1 − Perform Discrete Fourier Transformation (DFT) In this phase/step, the given signal is transformed from the time domain to the frequency ...
Read MoreThresholding-Based Image Segmentation in MATLAB
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 the pixel intensity values to separate different regions within an image. In this article, we will discuss learn the implementation of thresholding−based image segmentation using MATLAB programming. But before that let’s get into the basics of thresholding and its types. What is Thresholding? In digital image processing, the thresholding is ...
Read MoreHow to Convert RGB Image to YIQ Image using MATLAB?
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 MoreHow to Create a Dropdown Menu in MATLAB
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 ...
Read MoreHow to Count the Number of Circles in Given Digital Image Using MATLAB?
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 MoreHow to Create a GUI Button in MATLAB App?
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 ...
