When working on web development projects, there are often scenarios where you need to give a div tag the full height of the browser window. This can be particularly useful when creating full-page layouts, hero sections, or elements that need to span the entire vertical space. However, achieving this desired effect using CSS can be a bit tricky due to the nature of the CSS Box Model and the default behavior of height properties. In this article, we will explore different techniques to give a div tag 100% height of the browser window using CSS. We'll discuss the various CSS ... Read More
In this article, we will explore how to calculate covariance using MATLAB programming. But before that let’s have a look into the basic theory of covariance and importance. What is Covariance? Covariance is a statistical tool used to describe the correlation between two or more random variables. In other words, covariance is a measure that gives information about relationship between two or more variables. The covariable is primarily used to quantify the changes in one variable with respect to changes in another variables. The covariance between two random variables ‘A’ and ‘B’ is specified as cov(A, B), and ... Read More
Manipulating the DOM is an essential part of web development, and jQuery is a popular library that makes it easy to traverse the HTML DOM tree and select or modify elements based on their relationship with other elements. In this blog post, we will explore how to use jQuery to get or set elements based on their closest parent element that matches the specified selector. Using the Closest() Method The closest() method in jQuery is used to get the first element that matches the specified selector, searching through the element itself and its ancestors in the DOM tree. Here's an ... Read More
In digital image processing, filtering is defined as a process of modifying an image to enhance its visibility. Image filtering in digital image processing involves the use of some mathematical operations applied to each pixel of the image. It alters the pixel value to achieve the desired corrections like noise reduction, edge detection, image enhancement, etc. The image filtering is performed by applying a filter to the image. Where, the filter is nothing but a matrix of numbers that determine how to modify the pixel values. There are several types of image filters available based on different requirements. Some common ...

When working with dynamic web pages, it's often necessary to hide certain HTML elements based on specific conditions or user interactions. One common approach is to assign classes to these elements and then dynamically hide them using JavaScript. This provides a flexible and efficient way to control the visibility of elements without modifying the HTML structure. In this article, we will explore how to hide HTML elements by class using JavaScript. We'll discuss the importance of dynamically hiding elements, understand the concept of HTML classes, and learn different methods to select elements by class using JavaScript. We will then dive ...

According to the convolution theorem for Fourier transform, the convolution of two signals in the time domain is equivalent to the multiplication in the frequency domain. Therefore, if two signals are convolved in the time domain, they result the same if their Fourier transforms are multiplied in the frequency domain. For example, if x(t) and h(t) are two signals in the time domain and their Fourier transforms are X(ω) and H(ω) respectively. Then, their convolution in the time domain is given by, f(t) = x(t) * h(t) Here, the symbol ‘*’ represent the convolution of two signals. And the ... Read More
