Real time transmission of spaceborne and airborne images to the ground station is highly desirable in many telemetering applications. They also need to be sent through an error prone, time varying, wireless channel possibly under jamming conditions. Hence, a fast, efficient, scalable, error resilient image compression scheme is vital to realize the full potential of airborne reconnaisance. JPEG...

This paper presents a new method for remote and interactive browsing of long video sequences. The solution is based on interactive navigation in a scalable mega image resulting from a JPEG2000 coded keyframe-based video summary. The presented system is compliant with the new JPEG2000 part 9 “JPIP – JPEG2000 Interactivity, API and Protocol,” which lends itself to working under varying channel co...

For many contemporary applications, such as distributed multimedia systems, rapid transmission of images is necessary. Cost of transmission and storage tends to be directly proportional to the volume of data. Therefore, application of digital image compression techniques becomes necessary to minimize the cost. A number of digital image compression algorithms have been developed and standardized...

Image transmission with JPEG2000 can be speeded up by using regions of interest (RoIs). By such a mechanism, parts of an image not belonging to RoIs can be transmitted later or encoded at a lower bit rate. This paper describes a flexible dynamic RoI-scheme which supports the definition and handling of arbitrarily-shaped RoIs in JPEG2000. The scheme supports the dynamic definition and prioritiza...

In this paper the transmission of JPEG2000 and Motion JPEG2000 codestreams in 802.11 WLAN environment is analized. The issues related to the transmission of JPEG2000, using non reliable protocols as UDP-RTP, are investigated and a proper protection scheme for dealing with such an environment is presented, along with the obtained performance with different systems parameters. The proposed techni...

The need for high-performance image compression is becoming greater and greater as digital imagery finds its way into many areas of everyday life. JPEG2000 is the state-of-the-art compression standard emerges from the Joint Photographic Experts Group (JPEG) working under the auspices of the International Standards Organization. The new standard out performs the older JPEG standard by approximat...

Objective and subjective quality assessment is still a challenging problem in various image processing tasks. For instance, the context of compression, most conducted studies have focused on datasets encoded using standard algorithms such as JPEG JPEG2000. In this paper, we propose to further investigate issue presence neural networks-based compressed images. More precisely, new database images...

We review the standard JPEG2000 for still image compression and mention some typical applications. Special weight is put onto the core coding system described in Part 1 and the compound image file format for document imaging described in Part 6 including a section on image segmentation. Index Terms — JPEG2000, still image compression, mixed raster graphics, segmentation

In this work, a performance evaluation of AVC Intra and JPEG2000 in terms of rate-distortion performance is conducted. A set of High Definition sequences with different spatial resolutions is used for this purpose. Results obtained show quite competitive performance between two coding approaches, while in some cases, AVC Intra, in its High Profile, outperforms JPEG2000.
