Virtual Drawing using Python and OpenCV | Computer Vision
A virtual drawing project with color tracking, using Python and OpenCV library.
1.The desired color is being selected for tracking by defining the lower and upper color as numpy arrays in the code. Here blue color is being selected.
2. The maximum contour area (of the chosen color) is being calculated.
3. Calculation of the center of maximum contour.
4. Color is being tracked and when the center of max contour is inside a rectangle then the corresponding color, is being selected and used for drawing in both Frame and black Canvas.
5. When center of max contour is inside the region containing word «SAVE» (or by pressing «s/S») the current drawing on black Canvas is being saved in local file.
