Real Time Face Recognition with Raspberry Pi and OpenCV Face Recognition is getting increasingly popular and most of us are already using it without even realizing it. Be it a simple Facebook Tag suggestion or Snapchat Filter or an advanced airport security surveillance, Face Recognition has already worked its magic in it. China has started using Face Recognition in schools to monitor student’s attendance and behaviors. Retail… |

Object Detection using Python OpenCV We started with learning basics of OpenCV and then done some basic image processing and manipulations on images followed by Image segmentations and many other operations using OpenCV and python language. Here, in this section, we will perform some simple object detection techniques using template matching. We will find an object in an image and then we will describe its… |

Image Segmentation using OpenCV - Extracting specific Areas of an imageIn the previous tutorials, we have used OpenCV for basic image processing and done some advance image editing operations. As we know, OpenCV is Open Source Commuter Vision Library which has C++, Python and Java interfaces and supports Windows, Linux, Mac OS, iOS and Android. So it can be easily installed in Raspberry Pi with Python and Linux environment. And Raspberry Pi with OpenCV and attached… |

Installing OpenCV on Raspberry Pi using CMake Earlier day’s computer obtained input information from keyboards and mouse, now they have evolved to be able to process information from images and videos. The ability of a computer (machine) to extract, analyze and understand information from an image is called as Computer Vision. In recent years the capability of Computer vision has become sophisticated enough, not only to… |

Image Manipulations in Python OpenCV (Part 1) In the previous tutorial, we have learned about OpenCV and done some basic image processing using it like grey scaling, color saturation, histogram, color spaces, RGB component etc. As told in the previous tutorial, OpenCV is Open Source Commuter Vision Library which has C++, Python and Java interfaces and supports Windows, Linux, Mac OS, iOS and Android. So it can be… |

Getting started with Python OpenCV: Installation and Basic Image Processing Art is a way of seeing, and they say seeing is believing, but the opposite is also true, believing is seeing and it’s really hard to imagine living in this world without the gift of vision – our eyes, how wonderful it is being an infant when our eyes just open we see the world and started to recognize and see the world around us but as the time passes by, the same wonderful… |

Car Number Plate Detection Using MATLAB and Image Processing Have you ever wonder that how an ANPR (Automatic Number Plate Recognition) system works? Let me tell you the concept behind it, the camera of the ANPR system captures image of vehicle license plate and then the image is processed through multiple number of algorithms to provide an alpha numeric conversion of the image into a text format. ANPR system is used at many places… |

Getting Started with Image Processing using MATLAB Imagine pointing your camera to some object and the camera tells you the name of that object, yes, Google Lens in Android smart phones is doing the same thing using Image Processing. This gives computer a vision to detect and recognize the things and take actions accordingly. Image processing has lot of applications like Face detection & recognition, thumb impression,… |
