JavaCV Tutorial 1 -Basics





In this tutorial I've explained some simple image transformation techniques such as converting the RGB image into a HSV and Grayscale and saving the image file in different locations .
In "cvWaitKey()" function, you can include an integer value to indicate the amount time that the function has to wait for the user input.
Eg: cvWaitKey(1000) will wait for 1second for user I/p and automatically executes the statements below it if doesn't get any user i/p within the time specified.
