OpenCV provides the function cv2.copyMakeBorder() to add borders in images. To add border in an image, you could follow the steps given below − The first step is to import required libraries. In all below Python examples the required Python library is OpenCV. Make sure you have already installed it. The next step is to read an input image using the cv2.imread() function. Specify the full image path with image types (.jpg or .png). Specify different parameters to the function cv2.copyMakeBorder(). The different parameters to be specified are src, dst, top, bottom, left, right, borderType, and value. Call ... Read More
To find and draw the extreme points of an object in the input image, we could follow the steps given below − The first step is to import required libraries. In all below Python examples the required Python library is OpenCV. Make sure you have already installed it. The next step is to read an input image using the cv2.imread() function. Specify the full image path with image types (.jpg or .png). Convert the input image to grayscale. Apply thresholding on the grayscale image to create a binary image. Adjust the second parameter to get a better contour ... Read More
There are different types of muse events such as left or right button click, mouse move, left button double click etc. OpenCV provides us with different types of mouse events such as cv2.EVENT_LBUTTONDOWN for mouse left button down, cv2.EVENT_RBUTTONDOWN for right button down, cv2.EVENT_LBUTTONDBLCLK for left button double click and others. A mouse event returns the coordinates (x, y) of the mouse event. To perform an action when an event happens, we define a mouse callback function. We use mouse events to draw circles on the image. Steps To draw circles using mouse events, follow the steps given below ... Read More

This article is meant for explaining the important differences between web page and website. But, before going into the differences, let's have a basic overview of what ... Read More
The most basic difference between the waterfall model and the RAD model is that the waterfall model is a linearly-sequential life cycle model of software development in which software testing is done after the completion of all coding phases. On the other hand, RAD (Rapid Application Development) is an incremental model of software development. Read through this article to find out more about the waterfall model and the RAD model and how they are different from each other. What is Waterfall Model? Waterfall Model is the classical model of software development where each phase of software development is completed in ... Read More
There are various application programs that we can use to access the resources of a remote machine. Telnet and SSH are the primary client server application programs that use remote terminal service which allows a user at one site to interact with a remote timesharing system at another site as if the user’s keyboard and a display is connected directly to the remote machine. Telnet and SSH both are Layer7 application layer protocols and both use TCP (Transmission Control Protocol) at the transport layer. In this article, we will discuss the important differences between SSH and Telnet. But before going ... Read More
Both spear phishing and whaling are types of cyberattacks. Spear phishing is a type of phishing attack in which scammers install malware on the targeted user’s system in addition to stealing data for fraudulent objectives, whereas whaling is a cyberattack on high profile persons such as CEOs, CFOs, celebrities, politicians, etc. Whaling is a relatively highrisk strategy as compared to spear phishing. Read through this article to find out more about spear phishing and whaling and how they are different from each other. What is Spear Phishing? Spear Phishing is a type of email phishing attack where a personalized email ... Read More
Software testing involves only the testing of software parts of the system, while embedded testing involves the testing of both software and hardware parts of the system. Read through this article to find out more about software testing and embedded testing and how they are different from each other. What is Software Testing? Software testing refers to verifying and validating the behavior of the software developed. It ensures that software works as expected without any defect. It also helps in documenting that software is meeting the requirements and is ready to use. Software testing also checks the exceptions and error ... Read More
