Image Compression: Waveletbased Approach,Used
Delivery time: 8-12 business days (International)
Compression of digital images has been a topic of research for many years and a number of image compression standards have been created for different applications. This thesis focuses on some key technologies for image compression, namely waveletbased image coders that combines transform coding with subband coders and carried out a comparative study of waveletbased coding for still images using second generation wavelets via lifting scheme. Wavelet coders apart from offering superior compression ratios have also very useful features such as resolution scalability. There has been recent interest in building reversible integer transforms using lifting scheme for image compression. These transforms allow both lossless and lossy decodingby resolution or accuracy using a single bit stream.By integrating lossy and lossless compression in a natural fashion, a single image compression method provides excellent lossy performance as well as supporting many applications that require the ability to exactly recover the original image.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
