Virtual Keyboard

A simple virtual keyboard created using OpenCV and Python which has 26 alphabets and a space bar.

What have I done

The secret here is the area of the yellow paper I am wearing on my fingers. When I bring the paper near to the camera, the area of the paper as seen by the camera increases. When it is moved back the, the area of the paper as seen by the camera decreases. This is the simple idea that I have used to detect the click. The position of the click determines the key press that is to be simulated.
The keyboard creation is a bit complicated process. I hope that the code will be able to explain it.

Requirements

  1. PyAutoGui
  2. OpenCV 3

Usage

First run the range-detector.py to set the range for the mask for colour segmentation. The easiest way to use it is to put the yellow paper in front of the camera and then slowly increasing the lower parameters(H_MIN, V_MIN, S_MIN) one by one and then slowly decreasing the upper parameters (H_MAX, V_MAX, S_MAX). When the adjusting has been done you will find that only the yellow paper will have a corresponding white patch and rest of the image will be dark. Then run the virtual_keyboard.py file.
python3 range-detector.py -f HSV -w
python3 virtual_keyboard.py

Virtual-Mouse

Control your mouse using your webcam

Requirements

  1. PyAutoGui
  2. OpenCV 3
  3. Numpy

Usage

First run the range-detector.py to set the range for the mask for colour segmentation. The easiest way to use it is to put the yellow paper in front of the camera and then slowly increasing the lower parameters(H_MIN, V_MIN, S_MIN) one by one and then slowly decreasing the upper parameters (H_MAX, V_MAX, S_MAX). When the adjusting has been done you will find that only the yellow paper will have a corresponding white patch and rest of the image will be dark.Press 'q' to exit. Your configuration will be saved. Then run the mouse.py file.
python3 range-detector.py -f HSV -w
python3 mouse.py
Project is made with the help Dibakar Saha's project on Virtual Keyboard and Virtual Mouse.

Getting Started with YOLO object detection with sample code and detection

Image
Intro You only look once (YOLO) is a system for detecting objects on the  Pascal VOC  2012 dataset. It can detect the 20 Pascal object classes: person bird, cat, cow, dog, horse, sheep aeroplane, bicycle, boat, bus, car, motorbike, train bottle, chair, dining table, potted plant, sofa, tv/monitor YOLO is joint work with  Santosh ,  Ross , and  Ali , and is described in detail in our  paper . How it works All prior detection systems repurpose classifiers or localizers to perform detection. They apply the model to an image at multiple locations and scales. High scoring regions of the image are considered detections. We use a totally different approach. We apply a single neural network to the full image. This network divides the image into regions and predicts bounding boxes and probabilities for each region. These bounding boxes are weighted by the predicted probabilities. Finally, we can threshold the detections by some value to only see high scoring detections:

How to remote control others computer

Remote desktop connections and file sharing Today we will learn how to make remote system connections and file sharing among them. Procedure to make Remote connections among Systems: To configure a remote desktop connection between a remote Windows 7-based computer or windows 8 and a local computer running one of the versions of Windows listed earlier in this article, follow these steps. Step 1: Configure the Remote Computer On the remote Windows 7 or 8 Professional-based computer, follow these steps: ●Click Start, and then right-click My Computer. ●On the shortcut menu that appears, click Properties. ●Click the Remote tab, and then click to select the Allow users to connect remotely to this computer check box. ●When you are prompted to confirm this change, click OK. ●Click Select Remote Users, and then click Add to specify additional user accounts to be granted remote access. NOTE: Administrators are automatically granted remote access privileges. When you are finished ad
