Facilitating Watermark Insertion by Preprocessing Media
There are several watermarking applications that require the deployment of a very large number of watermark embedders. These applications often have severe budgetary constraints that limit the computation resources that are available. Under these circumstances, only simple embedding algorithms can be deployed, which have limited performance. In order to improve performance, we propose preproces...
متن کاملPreprocessing media to facilitate later insertion of a watermark
There are several watermarking applications that require the deployment of a very large number of watermark embedders. These consumer applications have severe budgetary constraints that limit the computation resources that are available. Under these circumstances, only simple embedding algorithms can be deployed, which have limited performance. In order to improve performance, we propose prepro...
متن کاملInformed Embedding: Exploiting Image and Detector Information During Watermark Insertion
Usually watermark embedding simply adds a globally or locally attenuated watermark pattern to the cover data (photograph, music, movie). The attenuation is required to maintain fidelity of the cover data to an observer while the watermark detector considers the cover data to be “noise”. We refer to this as blind embedding. In [1], it was observed that the cover data is not noise, i.e. it is not...
متن کاملSoft Feature-Based Watermark Decoding with Insertion/Deletion Correction
Hard decisions constitute the major problem in digital watermarking applications, especially when content adaptive embedding methods are used. Soft-decision decoding, on the other hand, has proved to be performance gaining, often realized during forward error correction. But despite this insight, no adaptive watermarking approach integrates the adaptation process into soft decoding, up to now. ...
متن کاملGround Penetrating Radar Image Preprocessing for Embedded Object in Media
The detection of embedded object from ground penetrating radar GPR imagery is our goal. The GPR image is a cross sectional slices. The embedded objects are metal and/or plastic type. This research has many real world applications such as remote sensing, geology, medicine and civil. The proposed method starts with two dimensional 2D image preprocessing for each slice. The preprocessing involves ...
