Digital image watermarking means embedding information into image in such a way that it is imperceptible to a human observer, but can be easily detected by special computer algorithm. A digital watermark is a transparent, invisible information pattern that it is inserted into a suitable component of the data source by using a specific algorithm. Please note that this is one of a early research projects, with some format drawbacks and background experience lackage as well..
