simple color tracking using opencv(no machine learning mombo jambo!)

Image
                              In this method we are using opencv and python for identifying a color and hilight it. this method uses the simple Bitwise and operation and image "HSV(hue,saturation,value)" manupulation of colors.                      The HSV value of image is represent the original colors of image though the RGB or BGR cannot tell the difference between the levels of colors hence this method only to work with HSV images since the HUE tells the color and saturation tells the level of color.                       here i'm tracking blue levels of colors in HSV u can track any color u want you need the hsv value for that, i suggest to use max value of upper color and min value for lower colorat start and play around the values untill u get statisfied results or just google it!.                      To get started u need few things, and just few line of codes you get ur face detection. we need the following things to get started: 1.python 3 recent would be nice

face detection using HAAR'S CASCADE with python In this tutorial we're gonna look into a face detection using "HAAR's CASCADE" algorithm in open cv. haar's cascade a is face detection classifier built-in  opencv for face and many more detection. Haar's cascade is originally developed from viola-jones algorithm. but it's not perfect it is prone to noise often, but for just simplicity we use it today. "using this method we can also detect many other features like face,eyes,full body,lowerbody,russian number_plates,etc.." here the same method modified for video face detection to get started u need few things, and just few line of codes you get ur face detection. we  need the following things to get started: 1.python 3 recent would be nice! 2.opencv lib package installed using pip 3.laptop/desktop with webcam step 1:               go to www.python.org and download latest version of python3  choose the install python along with pip and Option say
