Digital cameras currently have a number of features that create better quality images with less digital grain, higher resolution, and improved color fidelity. However, these improvements in digital cameras have meant that image sizes continue to become larger and larger. This is where lossless compression ratios for JPEG2000 can help reduce image sizes, while concurrently maintaining the quality of images. In fact using lossless JPEG2000 compression format a 69 MB file can be compressed to about 12 MB. Also while using the JPEG2000 format a user can choose the specific lossless compression ratios for JPEG2000 that they need. Good lossless compression ratios for JPEG2000 format can be achieved as JPEG2000 works to preserve transparency in images. Additionally JPEG2000 allows users to use masks so that important parts of an image can be saved with lower data compression compared to other parts that are rarely noticed by the viewer.
More About Lossless Compression Ratios for JPEG2000
Lossless compression ratios for JPEG2000 are competitive with those provided by JPEG-LS. Moreover the lossless compression ratios for JPEG 2000 are highly scalable. When comparing JPEG 2000 with JPEG-LS and PNG, even though JPEG 2000 does not perform very well, it still holds its own and can efficiently deal with various image types. Several people prefer to use the JPEG2000, as the good lossless compression ratios for JPEG2000 allow the format to compress various files types efficiently. Even when comparing the lossless compression ratios for JPEG2000 with JPEG there is noticeable difference in terms of flexibility of the codestream.
The Details of Lossless Compression
Lossless Compression Ratios for JPEG2000 are built around a special integer wavelet filter and is significantly slower. Additionally lossless compression ratios for JPEG2000 are worse than those got using the JPEG-LS format. However, where lossless compression ratios for JPEG2000 are better is when the format is used to compress pictures from digital cameras. Another plus point that works in the favor of JPEG2000 compression format is that it is widely supported, compatible with various software and is also scalable. In fact with lossless compression ratios for JPEG2000 set at an extreme 1:20 ratio JPEG2000 still performs better than JPEG.
