Digital watermarking includes a number of techniques that are used to imperceptibly convey information by embedding it into the cover data. There has always been a problem in establishing the identity of the owner of an object. In case of a dispute, identity was established by either printing the name or logo on the objects. But in the modern era where things have been patented or the rights are reserved (copyrighted), more modern techniques to establish the identity and leave it untampered have come into picture. Unlike printed watermarks, digital watermarking is a technique where bits of...

Now a day, the problem of detection of depressed person from the speech signal becomes initial matter. Analysis of voice for depressed and normal person is done using PSD and MFCC. Acoustic properties of speech have previously been identified as possible cues to depression, and there is evidence that certain vocal parameters may be used further to objectively discriminate between depressed and normal speech. In this research, these questions are addressed empirically using classifies configurations employed in emotion recognition from speech, evaluated on depressed/neutral speech database....

The Xilinx system generator, which provides a novel model based approach of carrying out various image processing applications. The model is prepared using Xilinx blockset that has a potential to be implemented on FPGA Devices. Multimedia authentication techniques are required in order to ensure trustworthiness of multimedia data. They are usually designed, based on two kinds of tools, Digital signature or Watermarking. Frequency domain based approach of watermarking is introduced in authentication system in order to get more feasibility in terms of better concealing and robustness of...
