Comparison of the JPEG2000 lossy image compression algorithm with WDR-based algorithms
نویسندگان
چکیده
We compare the new still-image compression standard, JPEG2000, with two competing algorithms based on the Wavelet Difference Reduction (WDR) technique of encoding. Our comparison shows that these WDR methods provide far simpler encoding while also providing essentially the same performance as JPEG2000 at moderately high to very high compression ratios. They provide useful alternative algorithms for applications where high compression ratios are needed and/or further processing of the compressed images is needed.

Compression can be done by lossy or lossless methods. The lossy methods have been used more widely than the lossless compression. Although, many methods for image compression have been proposed yet, the methods using intelligent skipping proper to the visual models has not been considered in the literature. Image inpainting refers to the application of sophisticated algorithms to replace lost o...
متن کاملSuper Resolution Based Image Compression Using Wavelet Transforms and Singular Value Decomposition
In this paper we propose a new lossy image compression technique which uses Singular value decomposition (SVD) and wavelet difference reduction (WDR) technique followed by resolution enhancement using discrete wavelet transform (DWT) and stationary wavelet transform (SWT). The input image is decomposed into four different frequency subbands by using DWT. The low frequency subband is the being c...

In this study, lossless grayscale image compression methods are compared on public palmprint image databases. Effect of lossy compression algorithms on biometric samples has been well studied. However, lossless compression algorithms on the compression ratios have little been appreciated. In this study, we review and the stateofart lossless compression algorithms and investigate the performance...

We propose an embedded, block-based, image wavelet transform coding algorithm of low complexity. The embedded coding of Set Partitioned Embedded bloCK (SPECK) algorithm is modified and extended to three dimensions. The resultant algorithm, three-Dimensional Set Partitioned Embedded bloCK (3D-SPECK), efficiently encodes 3D volumetric image data by exploiting the dependencies in all dimensions. 3...
