Image Compression Based on Multi-Scale Edge Compensation
نویسندگان
چکیده
In this paper we introduce a new image model called MSEC (Multi-Scale Edge Compensation) and implement an image compression system based on MSEC. MSEC consists of semantically meaningful components including edges of diierent types and scales, and the background. The MSEC-based image coding technique permits some image analysis operations such as edge detection, enhancement, and content-based retrieval to be carried out directly in the compression domain.

Image Representation Based on Multi - Scale EdgeCompensation
In this paper we deene an image model called MSEC (Multi-Scale Edge Compensation) and implement an image compression system based on MSEC. The idea is to represent the image by its multi-scale primal sketch and the background. The experimental results are positive; some important features of MSEC are proved.

Xiaohui Xue Dept. of Computer Science, Harbin Institute of Technology, Harbin, Heilongjiang, P.R.China [email protected] The mainstream of image compression research has been based on the Shannon Information Theory for years. In image data, there exist statistical redundancy, knowledge redundancy and psychophysiological redundancy, and the latter two cannot be handled by Shannon theory. Th...

Xiaohui Xue Dept. of Computer Science, Harbin Institute of Technology, Harbin, Heilongjiang, P.R.China [email protected] This short abstract illustrates the above example. 1. Scalability and recognition ability of edge detection of MSEC can be observed from (b)(c)(f)(g)(j)(k), in which two kinds of edges are handled separately, and, for each kind of edge, the detector responds to the exact...
متن کاملA Novel Color Image Compression Method Using Eigenimages
Since the birth of multi–spectral imaging techniques, there has been a tendency to consider and process this new type of data as a set of parallel gray–scale images, instead of an ensemble of an n–D realization. Although, even now, some researchers make the same assumption, it is proved that using vector geometries leads to better results. In this paper, first a method is prop...
متن کاملA Quantitative Investigation on the Effect of Edge Enhancement for Improving Visual Acuity at Different Levels of Contrast
Background: The major limitation in human vision is refractive error. Auxiliary equipment and methods for these people are not always available. In addition, limited range of accommodation in adult people when switching from a far point to a near point is not simply possible. In this paper, we are looking for solutions to use the facilities of digital image processing and displaying to improve ...
