A modified distortion metric for audio coding
Current audio coding standards employ the modified discrete cosine transform (MDCT) where overlapped frames of audio are windowed and transformed to the frequency domain. Encodin...

A Register File with Transposed Access Mode
We introduce a new register file architecture that provides both row-wise and column-wise accesses, thus allowing partitioned instructions to be used in columnwise processing with...

On Holographic Transform Compression of Images
: Lossy transform compression of images is successful and widespread. The JPEG standard uses the discrete cosine transform on blocks of the image and a bit allocation process that ...

Turbo coding for sample-level watermarking in the DCT domain
Coding at the sample level in still image watermarking takes advantage of avoiding a non-optimum initial diversity stage, used in many watermarking systems for tailoring Gaussian ...

Estimating Steganographic Capacity for Odd-Even Based Embedding and its Use in Individual Compensation
We present a method to compute the steganographic capacity for images, with odd-even based hiding in the quantized discrete cosine transform domain. The method has been generalize...

Estimation of optimum coding redundancy and frequency domain analysis of attacks for YASS - a randomized block based hiding sche
Our recently introduced JPEG steganographic method called Yet Another Steganographic Scheme (YASS) can resist blind steganalysis by embedding data in the discrete cosine transform...
