visual communications and image processing ii 1987
作者: Dubois, E. Rahmouni, Y. Lortie, F. INRS Telecommunications 3 Place du Commerce VerdunQCH3E 1H6 Canada
Two quantization methods for high quality image coding are presented. The goal in both methods is to keep subjective distortion below visual threshold. The first method is a discrete cosine transform coding system. Th... 详细信息

visual communications and image processing ii 1987
作者: Chiang, A.M. Lincoln Laboratory MIT LexingtonMA02173 United States
The need for transmitting an image through a low data rate channel has led to the development of various image data compression techniques. Recently, transform image coding based on the discrete cosine transform (DCT)... 详细信息

visual communications and image processing ii 1987
作者: Hason, B. Zeevi, Y.Y. Technion - Israel Institute of Technology Faculty of Electrical Engineering Haifa32000 Israel
An image is modeled by a two-parameter stochastic process generated by splitting a pixel into a block of 2 × 2 pixels thereby obtaining a higher resolution image. This sequential reproduction process is achieved ... 详细信息

作者: Biemond, J. Looijenga, L. Boekee, D.E. Delft University of Technology Dept. of Electrical Engineering P.O. Box 5031 GA Delft2600 Netherlands
In this paper a pel-recursive Wiener-based displacement estimation algorithm is introduced for interframe image coding applications. This algorithm is based on the assumption that both the so-called update and the lin... 详细信息

visual communications and image processing ii 1987
作者: Stein, Michael C. Analytic Sciences Corporation 55 Walkers Brook Drive ReadingMA01867 United States
This paper discusses a new technique for object detection that uses fractals to model the natural background in a visible image. Our technique is based on the fact that fractalbased models have been found to be good m... 详细信息
