We present algorithms for the type-IV discrete cosine transform (DCT-IV) and discrete sine transform (DST-IV), as well as for the modified discrete cosine transform (MDCT) and it...
In this research, we propose to use the discrete cosine transform to approximate the cumulative distributions of data cube cells' values. The cosine transform is known to have...
An image compression system based on transform coding and zonal sampling is presented. It is based on the wellknown Chen-Smith coder, but with an improved technique for transform ...

In this paper, we present a new scheme of data representation for image-based objects. It allows the illumination to be changed interactively without knowing any geometrical infor...
This paper presents an algorithm for the low power implementation of the Discrete Cosine Transform on Single multiplier CMOS DSPs. The algorithm reduces power by a combination of ...
We describe a way to make a hypermedia meeting record from multimedia meeting documents by automatically generating links through image matching. In particular, we look at video r...

This paper presents a new superscalar architecture for fast discrete cosine transform (DCT). Comparing with the general SIMD architecture, it speeds up the DCT computation by a fac...
Traffic sign recognition is a difficult task if we aim at detecting and recognizing signs in images captured from unfavorable environments. Complex background, weather, shadow, and...
Distributed Arithmetic techniques are widely used to implement Sum-of-Products computations such as calculations found in multimedia applications like FIR filtering and Discrete Co...
Abstract. To handle signal processing algorithms such as the Fast Fourrier Transform (FFT) or the Discrete Cosine Transform (DCT) system designers have traditionally resorted to sp...
