kandi X-RAY | alpr Summary

alpr is a Python library typically used in Artificial Intelligence, Computer Vision, OpenCV applications. alpr has no bugs, it has no vulnerabilities and it has low support. However alpr build file is not available. You can download it from GitHub.

All old code for the Automatic License Place Recognition System that we wrote in 2009-2010. When I say old I meant that. I just fished this code from my old hard drive and didn’t try running. But it shouldn’t be very hard for you to get this going if you are really interested. Roughly the requirements will be: * OpenCV - * OpenCV cvBlobsLib - * Tesseract * Qt4.

            What is the difference between an OCR code repo on GitHub and their website where they bill you for it?
            Asked 2020-Dec-18 at 11:30

            I've been trying to look for models that I can use/train as a license plate detector and recognizer. Thing is every time I come across a GitHub repo, they offer off the shelf instructions on how to install dependencies, ready up the model, train and inference.

            What confuses me though, is sometimes they link to their website in order to get some API key to go with the code in order to continue training the model and i'm not sure whether the billing aspect of their website often refers to something that hinders me using their GitHub code or refers to something completely irrelevant like billing people to use the GUI (i.e. their website) to train a model instead of flat out doing it yourself from a CLI using their code.

            Can someone shed some light on how this generally works?

            TLDR: I'm looking, on GitHub, to use/train a model for an ALPR task but most link to their website as part of the instructions on how to continue with their code. How do I know when their websites, that include billings, actually hinder me from using their code on GitHub? (i.e. I don't want to pay for anything. I'd rather train and inference it myself)

            There are github repos of companies, they basically show a demo with their API's and there developers who upload it as a project or whatever. The Company you gave as an example shows a demo of their API's and asks you to buy a key and without that key you won't be able to access their API's I.e they are like a key to your house. What you have to do is make an API and host it. Here you want to do a license plate detector and recognize the character right? So what suggestion I have for you is:

            1. Make a haar-cascade classifier for detecting the number plate
            2. Train a mnist model in scikit or whatever library you prefer.
            3. Make a flask application of the same or any other web framework app
            4. Host it Heroku
            5. Heroku is a like a computer in cloud you can deploy several application and deploy it. 6.but everything is not free there for example if you want to name your website car-detector, you won't be able to do in free tier instead your url will look like and if you want a custom domain you have to pay for it and also, if you want to increase the performance of the app you have to pay for it

            Here is an flask opencv python app for you to start with

            SyntaxError: Unexpected end of JSON input: ALPR using Node and Javascript
            Asked 2020-May-01 at 18:11

            The program prints perfectly when there is no License Plate in the frame, but when there is, I get the SyntaxError. Node.js and OpenALPR is installed. Photos are successfully being taken also.

            There is a space at the end of the JSON.



            No detection on googlecolab or Kaggle kernel
            Asked 2020-Apr-29 at 12:16

            I am creating an Automatic license plate recognition for Indian plates. I trained separate models for vehicle detection, license plate detection, and character recognition. I am trying to extract frames from video and process one at a time.

            I am using the this darknet framework.

            my code on github

            The problem is whenever I run it on my local machine it works fine and gives the following output: see this image of output



            Answered 2020-Apr-29 at 12:16

            I somehow found the answer by myself. I modified the configuration file for all models.



            Numpy Array operation Y[ ..., 0]
            Asked 2020-Feb-18 at 12:58

            Just a quick question,

            I came across a NumPy array operation which is important for the code and i cannot understand what this does.



            Answered 2020-Feb-18 at 12:58

            In a 2d numpy array this should give you the first element of each nested list, so for example:

            Install alpr

            You can download it from GitHub.
            You can use alpr like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
