HSV color space is more often used in machine vision owing to its superior performance compared to RGB color space in varying illumination levels. Often thresholding and masking is done in HSV color space. So it is very important to know the HSV values of the color which we want to filter out. HSV color space of OpenCV is a bit complicated than other software programmes like Gimp, Photoshop etc.So I have written a small python script to grab frames from a camera, and print the HSV value of the pixel under the cursor
I built a small robot to detect an object using image processing techniques and when the object is found, it goes near to it and picks it up.
The steps for training a haar classifier and detecting an object can be divided into :
Let us see all these steps in detail. Continue reading
OPENCV is an open source image processing library developed by Intel and currently maintained by WillowGarage. It is very powerful and can be coded in C/C++ or Python. I chose C, as it is more comfortable to me.
