Lossless Compression in MPEG4 Videos
نویسندگان
چکیده
This work considers object repetition, which means the occurrence of same object with similar motion is repeated in two or more frames. A single video is divided into several frames. All the objects are extracted from the stationary background and their features like motion and shape are preserved. After extraction, a two step compression is employed in which the algorithm checks for the continuous motion of all objects and then the video sequence are segmented. Now, the segmented video is compressed. This methodology maintains the video quality of the compressed video to be the same as source video.

An Evaluation of Motion JPEG 2000 for Video Archiving
Motion JPEG 2000 (MJ2) is one potential format for longterm video preservation. The format is attractive as an open standard with a truly lossless compression mode. Currently, three software-only MJ2 implementations are readily available, from the Open JPEG 2000 project, from the Kakadu project, and (incorporating Kakadu) from vendor Morgan Multimedia. These are given a snapshot evaluation here...

MPEG-4 Scalable Lossless Coding (SLS) is one of the latest extensions to the MPEG-4 audio coding standard. It provides a scalable lossless extension of the well-known MPEG4 AAC codec. The lossless enhancement is performed in a finegrain scalable way, starting from the AAC core signal in small steps all the way up to a numerically lossless representation, thus also including near-lossless compre...
متن کاملLossless Microarray Image Compression by Hardware Array Compactor
Microarray technology is a new and powerful tool for concurrent monitoring of large number of genes expressions. Each microarray experiment produces hundreds of images. Each digital image requires a large storage space. Hence, real-time processing of these images and transmission of them necessitates efficient and custom-made lossless compression schemes. In this paper, we offer a new archi...

متن کاملDevelopment of Lossless Compression Techniques for Biology Information and Its Application for Bioinformatics Database Retrieval
We are developing lossless encoding techniques for multimedia data such as sounds [1], images and videos. This presentation shows an integrated lossless encoder software “G-encoder”, which supports several biology information formats such as DNA sequences, amino-acid sequences, protein 3-D structures and microarray analysis images. We found our proposed compression tool gave higher compression ...
