  • Lane change detection of vehicle

    Time:2021-10-16

    Author | hitesh valechaCompile VKSource: towards Data Science In this tutorial, we will learn how to use computer vision and image processing to detect whether a car changes lanes on the road. You must have heard that opencv Haar cascade can detect faces, eyes, cars, buses and other objects? This time, let’s use this simple […]

  • How to get started with image processing???

    Time:2021-8-10

    Recently, someone asked me how to study image processing, how to get started and how to apply it. I was speechless for a moment. Think about it carefully. I have also done two years of image research, done two innovative projects and issued two papers. It is also a little experience, so I summarize and […]

  • PHP image processing imagestring add image watermark and text watermark operation example

    Time:2021-7-28

    This paper describes the operation of adding image watermark and text watermark in PHP image processing imagestring. Share with you for your reference, as follows: Imagestring add image watermark <?php header(“Content-Type: text/html;charset=utf-8”); //Specify picture path $src = ‘001.png’; //Get picture information $info = getimagesize($src); //Get picture extension $type = image_type_to_extension($info[2],false); //Dynamically import pictures into memory […]

  • Bid farewell to code copy and paste and extract pytorch middle layer features in a fool’s way

    Time:2021-3-17

    In the process of image generalization, the ability of feature extraction is very important. This article starts with the WeChat official account, “PyTorch developer community”. Feature extraction is widely used in machine learning, pattern recognition and image processing. Starting from the initial set of measurement data, it constructs information and non redundant derived values, namely […]

  • Python image processing operation based on tensor flow

    Time:2020-11-13

    This paper describes the python image processing operation based on tensor flow. For your reference, the details are as follows: In the deep learning of images, sometimes the number of pictures may be insufficient, or we hope that the network can learn more. At this time, we can process the existing image data to make […]

  • The basis of canvas image processing

    Time:2020-9-7

    A few days ago, my predecessors recommended an interesting project real time person removal. This project uses TensorFlow.js And the image processing in canvas realizes the disappearance of characters in the video. Take this opportunity to review the basic canvas image processing. Basic API The image processing ability of canvas processes pixel data through imagedata […]

  • AOE engineering practice image processing in bank card OCR

    Time:2020-3-22

    AOE engineering practice image processing in bank card OCR Author: yangke Recently we have developed a bank card OCR project. The demand is that after shooting the bank card with a mobile phone, the card number on the card can be identified by reasoning. In the process of engineering development, we found that the image […]

    Time:2020-1-21

    Unbuntu 18.04 with OpenCV This time, when doing mathematical modeling, problem a involves image processing, so it’s time to install an OpenCV. I wanted to learn it before. This time, it’s a chance for practice. Installation dependency sudo apt install cmake sudo apt install build-essential cmake git libgtk2.0-dev pkg-config libavcodev-dev libavformat-dev libswscale-dev libjasper Error: unable […]

  • Step by step derivation from full connection network to convolution neural network (no formula for group diagram)

    Time:2019-12-29

    In image analysis, the convolutional neural network (CNN) is superior to the full connected (FC) in time and memory. Why is that? What is the advantage of convolutional neural network over all connected network? How is convolutional neural network derived from all connected network? Where does the term convolutional neural network come from? These questions […]
