Image Compression Using Embedded Zero-tree Wavelet Coding (EZW)
نویسندگان
چکیده
Transform coding forms an integral part of compression techniques. In transform coding a reversible linear transform is used to map the image into a set of coefficients which are then quantized and coded. The advantage of using a transform is that it packs the data into a lesser number of coefficients. The main purpose of using the transform is thus to achieve energy compaction. The type of transform used varies between different codecs.

متن کاملA Modified Embedded Zero-tree Wavelet Method for Medical Image Compression
The Embedded Zero-tree Wavelet (EZW) is a lossy compression method that allows for progressive transmission of a compressed image. By exploiting the natural zero-trees found in a wavelet decomposed image, the EZW algorithm is able to encode large portions of insignificant regions of an still image with a minimal number of bits. The upshot of this encoding is an algorithm that is able to achieve...

The transport of images across communication paths is an expensive process. The limitation in allocated bandwidth leads to slower communication. To exchange the rate of transmission in the limited bandwidth the Image data must be compressed before transmission. JPEG2000 image compression system follows huffman coding for image compression. Embedded zero tree wavelet (EZW) coding exploits the mu...
