ID card detection using Emgu and Tesseract OCR

Image
Tesseract is an open source OCR engine maintaining by the google, in this post we are going to use Tesseract OCR to identify the text from ID card. ID card  Image processing: We need to apply some image processing to the image before OCR the image, please refer the below link to improve the OCR accuracy by applying the image processing to the input image. https://github.com/tesseract-ocr/tesseract/wiki/ImproveQuality I am going to use the .Net library Emgu to apply image processing to the image, Emgu is a cross platform .Net wrapper to the OpenCV. Rescaling: Tesseract works best on images which have a DPI of at least 300 dpi, so we need to rescale input image to get the accurate result. imgResize = sourceImage.Resize(2, Inter .Linear); Binarisation: This is converting an image to black and white img_gray = imgResize.Convert< Gray , Byte >().SmoothGaussian(5).ThresholdBinary( new Gray (trackBar1.Value), new Gray (255)); After Binarisation

Bluetooth communication between Arduino and Windows Phone 8.1

Image
W ireless communication is very useful in many real time situations such as home automation systems, we can establish a wireless communication using Bluetooth, WIFI and Zigbee. Bluetooth is very cheap and easily available so we first start with  Bluetooth. Please check my previous post to setup  Windows Remote Arduino with USB. come lets play with Bluetooth Parts we need Hardware: Arduino Uno R3 board – 1 Buletooth module HC-05 – 1 Arduino USB connector - 1 Light Emitting Diode (LED) –1 Bread board- 1 Software: Windows 8.1OS Visual studio 2013 Set up a connection The HC-05 bluetooth module come up with 6 pins, refer the below image. Connect VCC to 5V Connect GND to GND pin of Arduino Connect Bluetooth RX to Arduino TX pin 1 Connect Bluetooth TX to Arduino RX pin 0 refer the below connection diagram. Note: The standard firmata must be loaded in the arduino, check my previous post set the baud rate to 9600 in standard firmata as given bel

I got my Ardunio

Image
I got my Arduino uno board last week, purchased from online snapdeal store, the interest thing is now windows supports arduino . The Windows Remote Arduino help you to control arduino from windows 10 Universal  Windows  Platform ( UWP) and windows 8.1 universal applications, that means you can control arduino from windows pc or Windows Phone using either USB or Bluetooth. Check the following link for more information. https://ms-iot.github.io/content/en-US/win10/SetupPCWRA.htm come lets play with hardware My first experience with Arduino I have successfully completed the “Blink” sample with  Windows Remote Arduino library. Parts Required to do this experiment: Hardware Software Arduino Uno R3 board – 1 Arduino USB connector- 1 Light Emitting Diode (LED) –1 Bread board- 1 Windows 10 OS Visual Studio 2015 latest enterprise version Arduino IDE latest version https://www.arduino.cc/ Load the StandardFirmata to the arduino: Before jump in
