I'm reading electronics. I worked in digital watermarking (which is a discipline that involves inserting a mark in a digital document in order to protect this digital document against illegal copying), or save information in order to transfer it through a network like a local network or internet. The procedure of the mark extraction with old methods inspires me to build algorithms based on the wavelet transform.
Now I'm working on algorithms' optimization by using polynomial transforms.
