The still image lossy compression standard - JPEG
Reducing image files will be an important procedure when we transmit files across networks (Wiseman, Schwan & Widener, 2004). or when we would like to archive libraries. Usually, JPEG can remove the less important data before the compression; hence JPEG will be able to compress images meaningfully, which produces a huge difference in the transmission time and the disk space. The processing time...
متن کاملEfficient JPEG 2000 Image Compression Scheme for Multihop Wireless Networks
When using wireless sensor networks for real-time data transmission, some critical points should be considered. Restricted computational power, reduced memory, narrow bandwidth and energy supplied present strong limits in sensor nodes. Therefore, maximizing network lifetime and minimizing energy consumption are always optimization goals. To overcome the computation and energy limitation of indi...
متن کاملJPEG 2000: The Next Generation Still Image Compression Standard
JPEG 2000, an emerging standard for still image compression, is discussed at length. To commence, a high-level introduction to JPEG 2000 is given. This is followed by a detailed technical description of the JPEG-2000 codec. Next, the codec is evaluated. The complexity of its various components is analyzed, and its performance is compared to other existing standards. With its excellent coding pe...
متن کاملBasic Image Compression Algorithm and Introduction to JPEG Standard
Because of the explosively increasing information of image and video in various storage devices and Internet, the image and video compression technique becomes more and more important. This paper introduces the basic concept of data compression which is applied to modern image and video compression techniques such as JPEG, MPEG, MPEG-4 and so on. The basic idea of data compression is to reduce ...
