In MATLAB, "linear filtering" is a technique used to apply a linear filter to a digital image. The fundamental principle behind the working of linear filtering is convolution. This article is meant for explaining the concept of linear filtering and how to perform linear filtering without using the "imfilter" function in MATLAB. What is Linear Filtering? In digital image processing, the process of applying a linear filter (also called convolution kernel) to a digital image is called linear filtering. The working of linear filtering is based on the concept of convolution. In the process of linear filtering, a convolution ... Read More

In mathematics, there are several types of numeric values such as integers (having no fractional part), floating point numbers (having fractional parts separated by a decimal), and more. In some data analysis and other computational applications, we are given floating point numbers that contain a decimal part, i.e., digits after a decimal point. But we require only integers. Hence, if you are using MATLAB as your data processing tool, then you can use it to remove decimals present in the given number. This tutorial is primarily meant for explaining the different methods of removing decimals from a given number using ... Read More
