الملخص الإنجليزي

The huge usage of digital multimedia via communications, wireless communications, Internet, Intranet and cellular mobile leads to incurable growth of data flow through these Media.

The ability to transmit video and support related real-time multimedia applications are considered an important issue in mobile networks.

Video streaming, video conferencing, online interactive gaming and mobile TV are applications expected to support the viability and survival of next generation mobile wireless networks.

Wavelet transform is an efficient method that can be used to perform an efficient compression technique.

This dissertation deals with the developing of an efficient video compression based on frames difference approaches that concentrated on the calculation of frames near distances (difference between frames).

The selection of the meaningful frame depends on many factors such as compression performance, frame details, frame size and near distance between frames.

Three different approaches are applied for removing the lowest frame difference (Zero difference Approach, Mean Difference Approach and Percentage Difference Approach).

Many factors are considered in system implementation to adapt image and video compression over mobile devices.

In this work, many images and video contents are tested to insure the efficiency of this technique, in addition a good performance result has been obtained, in which the best MSE & PSNR gives by Coiflets wavelets transform (Coif4) 133 & 26.92 respectively.

Also with 25 frames per second extracted, good results of the compressed video are obtained using subjective video quality assessment in which Mean Opinion Score (MOS) gives on the average (4.5/5) for the case of removing all zero difference frames and the lowest 5% percentage of the frames difference of the extracted frames
