IEEE International Conference on Image Processing

作者： R. Nygaard J. Hakon Husoy D. Haugland Department of Electrical and Computer Engineering Hogskoleni Stavanger Stavanger Norway

compression of image contours is an important problem in many contexts. An example is object oriented video coding, where efficient encoding of shape information of arbitrarily shaped objects is a major problem. This paper presents a method for compressing contours by extracting representative points from the original curve. By formulating the point selection problem as a graph theory problem, known optimization theory can be applied in order to yield optimal compression with respect to a given error bound. The contour is reconstructed based on linear interpolation among the extracted curve points. The method presented guarantees a minimal distortion for a given number of retained curve points. Compared to many other compression methods, this method shows superior performance.

European Signal Processing Conference (EUSIPCO)

作者： Pekka J. Toivanen LUT-yliopisto Lappeenranta FI

In this paper, a new image compresion method is presented. It is based on the use of the Distance Transform on Curved Space (DTOCS), which calculates an integer approximation of the weighted pseudo-Euclidean distance transform along discrete 8-paths, and topological raster patterns to determine coordinates for control points. The decompression is based on triangulating among the control points using Delaunay triangulation. The obtained images are compared to previously published methods and to the JPEG DCT-based method. It is shown that the obtained results are of the same quality as JPEG results and exceed other DTOCS and Delaunay based methods. It is also shown experimentally that the time complexity of the compression method presented in this paper does not depend on the number of control points, i.e. the compression ratio. Because of this and the locality of the decompression scheme this method could well be used in applications where a rapid flashing image is made more accurate over time.

Advanced blocs classification for fast encoding in fractal-based gray-scale images compression

IEEE International Conference on Image Processing

作者： K. Maalmi R. Benslimane Laboratoire de Transmission et de Tiraitament d 'Images Ecole Supérieure de Technologie de Fès

ISBN: (纸本)0818688211

Fractal-based images compression entails a computationally costly search for matching range and domain blocs. One way to remedy at this problem is to classify image blocs into categories and only search among domain blocs which are in the same category as the target range bloc. Since image blocs with a simple edge (blocs with a distinct edge running through them) are a very important portions of the perceptual information content in image, we propose in this paper a method to both identify and classify this kind of blocs according to their edge presentation. We refer to this method as forced classification (FC). This method is combined with other suitable methods of blocs classification available in the literature to allow a fast and efficient encoding of grey-scale images. The result is surprisingly good, the encoding time for 512/spl times/512 lena image is reduced by a factor of 37.52% than using only Yuval Fisher (1995) classification, while the loss of image quality is low.

Context modeling has recently drawn much research interest to improve the performance of a compression algorithm for binary data such as images. This is because it can help to remove the remaining statistical redundancy among the data after the prediction stage. In this paper, a simple context modelling scheme is proposed in the lossless compression of ionogram data. Experiments show that compared with the method without context modelling, this scheme can provide over 13% increase in the average compression ratio for the sample data files with almost nothing added to the computational complexity.

Data compression for Arabic text

Data compression for Arabic text

National Conference on Radio Science (NSRC)

作者： A.S. Mohamed A.H. El-Sawy S.M. Ahmad Department of Communication and Electronics Faculty of Engineering Helwan University Egypt

The huge amount of data that are being stored/or communicated between different terminals motivates the need for data compression. The compression of data helps in saving the required storage and transmission bandwidth, Several methods for data compression have been proposed in the literature. A new data compression technique is presented here. Its performance is investigated with respect to both English and Arabic texts. In this paper some of the Arabic text statistics are calculated, then the new technique and the other techniques are applied to different types of Arabic and English texts. A comparison is worked out, and an improvement in the compression ratio is observed.

A new method for reversible compression of multispectral images is presented. 3D data are decorrelated by means of an inter-band causal prediction obtained through the fuzzy switching of a set of predictors representative of 3D micro-patterns occurring across bands, whose coefficients are LS-estimated in a preliminary learning phase. The outcome residuals are entropy coded by exploiting context information. Results of compression on both Landsat TM and AVIRIS images show that the proposed approach outperforms other schemes reported by the most recent and advanced literature.

National Conference on Radio Science (NSRC)

作者： Yutao Feng E. Gelenbe C-Cube Microsystems Milpitas CA USA Department of Eiectrical & Computer Engineering Duke University Durham NC USA

We present a novel video compression system resulting in very low bit rates, using dynamic object oriented compression. Our method separates important objects from the background and from trivial details, so as to keep good visual quality of the objects of interest. The resulting bit rate can be significantly reduced by sacrificing information on less relevant parts of the scene, or from portions of the video sequence which are of less interest to the end users. The method is based on an active dynamic contour algorithm which tracks the external contour of designated objects, and which we improve to provide more accurate dynamic tracking. The performance of the object tracking algorithm, as well as of our compression scheme are presented. Experimental results concerning bit rates and video quality are provided and compared with respect to the standard H.263.

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)

作者： G.N. Ramaswamy P.S. Gopalakrishnan IBM Thomas J. Watson Res. Center Yorktown Heights NY USA IBM Thomas J. Watson Research Center Yorktown Heights NY USA

In this paper, we describe a new compression algorithm for encoding acoustic features used in typical speech recognition systems. The proposed algorithm uses a combination of simple techniques, such as linear prediction and multi-stage vector quantization, and the current version of the algorithm encodes the acoustic features at a fixed rate of 4.0 kbit/s. The compression algorithm can be used very effectively for speech recognition in network environments, such as those employing a client-server model, or to reduce storage in general speech recognition applications. The algorithm has also been tuned for practical implementations, so that the computational complexity and memory requirements are modest. We have successfully tested the compression algorithm against many test sets from several different languages, and the algorithm performed very well, with no significant change in the recognition accuracy due to compression.

IEEE-SP International Symposium on Time-Frequency and Time-Scale Analysis

作者： A. Przelaskowski Institute of Radioelectronics Warsaw University of Technology Warsaw Poland

An adaptive space-frequency quantization scheme in a scalar fashion applied to wavelet-based compression is presented. Because of strong demands due to detail preservation in lossy image archiving and transmission, as in for example medical applications, different modifications of uniform threshold quantization are considered. The main features of the elaborated procedure are as follows: fitting the threshold value to the local data characteristics in a backward way and quantization step size estimation for each subband as a forward and backward framework in the optimization procedure. Many tests conducted with a real wavelet compression scheme confirm the significant efficiency of the presented quantization procedures. The achieved total compression effectiveness is promising in spite of the simple coding algorithm.
