Image Contour Detection Using Neural Network-based Fractal Coding
In this paper, we propose to fix the selection of domain blocks when implementing fractal image coding with parallel neural network technologies. The obtained fractal code can be used to get the fine image contour after one iteration from any even gray-level images (except all black), as well as to reconstruct the original image after many times iteration from any images. At the same time, this...
متن کاملDigital Watermarking Using Fractal Image Coding
A new digital watermark approach based on fractal image coding is proposed in this letter. We present a way to use the fractal code as a means of embedding a watermark. The proposed approach has shown to be resistant to the JPEG lossy compression. Moreover, the digital watermark can be simply extracted from the watermarked image without resorting to the original image. key words: digital waterm...
متن کاملUsing Fractal Coding for Progressive Image Transmission
1. ABSTRACT Fractal coding is gaining in popularity as an efficient still-image coder. One drawback of conventional block-based fractal coders, however, is that they do not offer progressive image transmission. This paper proposes two new methods by which fractal image coders can progressively transmit the image data. The first method, the transmission-sequence-based fractal coder (TSFC), progr...
متن کاملGeometrical Coding For Medical Image Retrieval Using Transformed Contour Coding
In the approach of geometrical coding, curvature based coding are predominantly been used. As in various applications the processing data are large in count or large in representation and the available resources are very lower in count. In such resource constraint environment, the processing efficiency is decreased to very low level specially with processing delay factor. The current retrieval ...
متن کاملFractal Image Coding
This paper investigates the use of fractal coding for image compression and reconstruction. The encoder exploits self-similarity of the image at different resolutions, mapping larger blocks of the image to similar smaller blocks through a series of contractive transformations. The decoder can apply these transformations iteratively to any image, and recover the original. We show that varying th...
