I want to threshold a particular coloured object in the image...

The image is in HSV format... In the code using Core.inRange function, i don know the order of the arguments in the scalar..

            Core.inRange(src, new Scalar(H, S, I), new Scalar(H, S, I), dst);

Can any one tell me the exact order...i figured out that the second parameter is Hue... I m using android...

If you use OpenCV functions for getting HSV image, then the order of components is the same as in color space name: H, S, V. You can see color conversion functions source code in modules/imgproc/src/color.cpp:798.

My mistake was i didn't convert the image from default BGR to RGB..so the values had been going in the reverse order.
