A Novel LBG algorithm for Image Compression in Wavelet Transform Domain
نویسنده
چکیده
-The paper presents a novel LBG algorithm for image compression in wavelet transform domain. The performance of the algorithm is evaluated by using standard 512×512 benchmark still images and the results compared to the traditional well-known JPEG standard. The important metric of time and Peak Signal to Noise Ratio are used to evaluate the novel algorithm. The results show that the strength of the algorithm lies in the speed of operation as it is much faster than the JPEG standard. It has speed advantages of almost 41% over the JPEG standard. Further more, the accuracy of the prediction of the Novel algorithm is better than that of the JPEG standards.

Image Compression using Fusion of Hybrid Wavelet Transform and Vector Quantization
This paper proposes novel lossy image compression technique using hybrid wavelet transform and vector quantization. First hybrid wavelet transform consisting of two different component transforms is generated and applied on color images. Discrete Kekre transform (DKT) and Discrete Cosine transform (DCT) play role of base and local transform respectively in hybrid wavelet transform. In transform...

Image data require huge amounts of disk space and large bandwidths for transmission. Hence, imagecompression is necessary to reduce the amount of data required to represent a digital image. Thereforean efficient technique for image compression is highly pushed to demand. Although, lots of compressiontechniques are available, but the technique which is faster, memory efficient and simple, surely...
متن کاملA Systematic Image Compression in the Combination of Linear Vector Quantisation and Discrete Wavelet Transform
As the use of digital image is increasing day by day, and the amount of data required for an acceptable quality image is high, there begins a high necessity for image compression. Vector quantisation (VQ) is a novel technique for image compression. VQ is a lossy compression scheme, used to compress image both in spatial domain & frequency domain. One of the major disadvantages is high encoding ...

متن کاملA Novel Classified Residual Dct for Hyperspectral Images Scalable Compression
Transform−based lossy compression has a huge potential for image compression. In this paper, we propose a scalable lossy compression algorithm using transform technology for hyperspectral images. The novelty of this paper lies in the classified residual DCT (Discrete Cosine Transform) as a spectral decorrelator. The classified residual DCT is an improvement of the traditional DCT, which makes t...
