Qualitative Rating of Lossy Compression for Aerial Imagery by Neutrosophic WASPAS Method

Lossy dictionary-based image compression method

In this paper, we report on the new method of image compression. The method is based on LZ77 dictionary algorithm. We introduce two modifications such as quantization and noise levels. Experimental results presented in this paper prove that the new method of image compression gives promising results as compared with original LZ77 dictionary algorithm and JPEG2000. 2006 Elsevier B.V.

Map Generation from Aerial Imagery Using Data Compression

In this paper, we propose a new method to generate a digital map from the aerial photograph. For map generation, it is necessary to develop a technique to recognize various naturaland artificialobjects in the image by computer processing. In general, a photo image has spatial and spectral informations. It is desirable that these two informations are effectively utilized. A new method proposed h...

Application of Hybrid Fractal Image Compression Method for Aerial Photographs

This paper proposes a method to improve the performance of Fractal lmage Compression (FIC) technique by combining FIC (lossy compression) and another lossless method (in this case Huffman coding is used). This proposed method takes advantage on each techniques, the high compression ratio that can be provided by FIC and the infinite peak-to-peak signal to-noise ratio (PSNR) that can be provided ...

ON A LOSSY IMAGE COMPRESSION/RECONSTRUCTION METHOD BASED ON FUZZY RELATIONAL EQUATIONS

The pioneer work of image compression/reconstruction based onfuzzy relational equations (ICF) and the related works are introduced. TheICF regards an original image as a fuzzy relation by embedding the brightnesslevel into [0,1]. The compression/reconstruction of ICF correspond to thecomposition/solving inverse problem formulated on fuzzy relational equations.Optimizations of ICF can be consequ...
