I have calculated hu moments for a frame now i want to calculate the hu moments for each frame that represent a gesture. How to store the hu moments for each frame representing a gesture and how to calculate the orientation vector of a continuous gesture?

I don't believe the Hu Moments have a meaning that lets you compute the orientation. If the image is identical except for rotation, the moments should be identical too.

You can use the normal moments to compute an orientation: https://en.wikipedia.org/wiki/Image_m...
