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 red, green, and blue. RGB image is mainly used display color images on display screens. On the other hand, a gray scale image is one that uses only two colors, i.e. black and white to represents the elements in an image. In other words, a gray scale image is a ... 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, green, and blue are used to represent all the colors in the image. In the RGB image, each pixel of the image is represented by a combination of intensity values for these three colors. Therefore, the three intensity values of RGB colors determine the color of the pixel. In MATLAB, ... 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 Green and Blue. It is another popular color space in which images are represented based on red, green, and blue color intensities. In this article, we will study how to convert an HSI image into an RGB image using MATLAB programming. MATLAB provides a built−in function ‘hsv2rgb’ to convert an ... Read More
Time complexity is a measure of time, which determines the time required for the algorithm to execute. It also checks how the running time is being increased when the size of the inputs is getting increased. The time complexity is represented with the notation capital O, which sets an upper bound in the worst case performance of an algorithm. Whenever we design an algorithm we should keep in mind not only about the correctness but also about the time complexity and performance characteristics. For example, if an algorithm has time complexity O(n) that would take twice of O(n) to execute ... Read More
In digital image processing, the process of extracting a specific color or color range from an image with all other colors are discarded is referred to as color slicing. In an image, the color slicing is performed by creating a binary mask that selects all the pixels in the image that lies in the range of the specified color. Coloring slicing is generally used in specific color spaces such as RGB (Red−Green−Blue) color space or HSV (Hue−Saturation−Value) color space, etc. In this article, we will learn how to perform color slicing in HSV color space using MATLAB programming. In the ... Read More
The name-tools module is a python library which provides us the tools to work with the names. These are used in many applications likely data cleaning, text processing and Natural Language Processing etc. It has a several functions for comparing and managing the names. Installing name-tools Before working with the name-tools, we need to install it in the python environment. The following is the process for installing the name-tools. pip install name-tools After executing the above code, if you see the text below, then the installation is considered successful. Collecting name-toolsNote: you may need to restart the kernel ... Read More
HTML tables are commonly used to present data in a structured manner. Tables consist of rows and columns where each row represents a record and each column represents a field in that record. In some cases, you may want to group the content in the body of the table, such as when you have multiple data points that belong together. In this blog post, we will explore different methods to group body content in HTML tables. Method 1: Using the Element The simplest way to group body content in an HTML table is to use the element. The ... Read More
When designing a form for a website, it's important to consider the user experience and make it as easy as possible for users to fill out the form. One way to do this is by grouping related elements together so that users can quickly scan and fill out the form. In this blog post, we'll discuss how to group related elements in a form using HTML. What is Grouping in HTML Forms? Grouping in HTML forms involves grouping related form elements together, such as radio buttons, checkboxes, and text input fields. By grouping related elements together, you can make it ... Read More
When displaying data in an HTML table, it is often useful to group the header content of the table to provide more context to the data being displayed. Grouping header content can make it easier for users to understand the relationships between the data and to identify patterns or trends. In this article, we'll discuss several methods for grouping header content in an HTML table using HTML5. Method 1: Using the and Elements The most straightforward way to group header content in an HTML table is to use the and elements. The element is used ... Read More
In this article, we will learn how to calculate cumulative product in MATLAB. So, lets, start with the basic definition of cumulative product. What is Cumulative Product? A mathematical operation in which the product of a sequence of numbers is computed in a cumulative manner is called cumulative product. In the cumulative product, the product of elements of a sequence of numbers is computed up to the given index and the result obtained in each step is stored in the form of an array. To understand the what is the cumulative product? Let’s consider an example as follows. Let a ... Read More
