The operating system does not perform any functions on its own, but it provides an atmosphere in which various programs and apps can do useful work. The operating system may be observed from the point of view of the user or the system, and it is known as the user view and the system view. In ... Read More
Introduction Docker is a popular platform for deploying and running applications in a containerized environment. It provides an efficient way to package, distribute and run applications with all their dependencies. One of main advantages of using Docker is that it enables use of multiple databases in an efficient way using docker-compose. Docker-compose is a tool for defining and running multi-container Docker applications. It allows you to define configuration of different containers in a single YAML file, which can be used to start, stop and manage containers. In this article, we will discuss how to use multiple databases with Docker-compose. Prerequisites ... Read More
Introduction Image Segmentation is the process of dividing a digital image into smaller groups so that processing and analyzing the larger images becomes easier and simpler. Region and Edge-based segmentation are different types of Image Segmentation. Before diving into Region and Edge based Segmentation, let us have a brief overview of how segmentation is done. Image Segmentation In simpler terms, segmentation is the process of assigning specific labels to pixels in an image. A group of pixels with the same label become a segment of the larger image. For example, below are two images with their segmentation. In the ... Read More
