This new approach includes prefiltering, fuzzy logic image enhancing and obtaining of cluster centers by performing the zig-zag method in discrete cosine transform coefficients. After applying the new method on sample images at different number of clusters, Better compression ratio, performing time and good validity measure was observed.

An Algorithm for Image Clustering and Compression
This paper presents a new approach to image compression based on fuzzy clustering. This new approach includes pre-filtering, and fuzzy logic image enhancing to reduce undesirable noise effects on segmentation result; separation of image into 4x4 blocks and two dimensional discrete cosine transform; obtaining of peak values of cosine membership functions by combining of performing the zig-zag me...
متن کاملA Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization
This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...
متن کاملFuzzy Logic Based Hybrid Image Compression Technology
In this paper, the comparison between Hybrid Image Compressions methods and Fuzzy logic based image Compression is discussed. The Hybrid Comparison Method is a combination of both the DCT and DWT Image Compression method. When more than one compression technique are applied to compressed one image for high value of PSNR (peak signal to noise ratio) and CR (compression ratio) this process is cal...
