JPEG 2000 is a coding system and image compression standard. It has been introduced by Joint Photographic experts Group in 2000. JPEG 2000 has been created for superseding the true and natural discrete cosine transform based. The normal filename extension is .jpg2 for IEC and ISO 15444-1. There are numbers of file formats extension have evolved for JPEG 2000. By using numbers of file extension names, you can store several types of images properly. Also, it is having numbers of features and advantages which are helping you use it in the best way. There are some features discussed below.
It allows the users for superior compression performance
Also, allows the users for making multiple resolution representation
One of the best features of JPEG 2000 is progressive transmission through pixel and resolution accuracy.
It is so flexible to file format and file naming.
Also, it is fully supporting the transparency and alpha planes.Whereas there is the modest increase in the compression performance of the JPEG 2000 when compared to the JPEG, main benefit that is offered by the JPEG 2000 is significant flexibility of codestream. Codestream got after the compression of image with the JPEG 2000 is very scalable in nature, it means that it is decoded in many ways; for example, by truncating a code stream at a point, one might get the representation of an image at the lower resolution, and signal to noise– see the scalable compression. So, by ordering codestream in different ways, the applications will attain the important performance increases. But, as the consequence of flexibility, the JPEG 2000 needs encoders or decoders, which are complex & computationally demanding. One more difference, when compared with JPEG, is in the terms of the visual artifacts: the JPEG 2000 makes ringing artifacts, and manifested as rings and blur near edges in image, whereas JPEG makes ringing artifacts as well as ‘blocking’ artifacts, because of 8*8 blocks.
