The mathematical concept of a DCT transform is a powerful tool in many areas; it is also, served as an approach in image processing discipline. In this work an image is processed as three color channel. The correlated pixels values of an image can be transformed to a representation where its coefficients are de-correlated. The term "de-correlated" means that the transformed values are independent of one another. As a result, they can be encoded independently, which make it simpler to construct a statistical model. Correlated values are coded with run-length coding techniques while shift coding used to decode the DC term and the other five lifting values. In this work, we suggest to save the first five values from every block to keep it back without any significant errors. The obtained bit rates was extended to be within range (11.4 , 2.6), compression ratio (2.76 , 13.34 )the values of the fiedility parameters (PSNR) was within the range (31.61 , 46.21) for the lena test image in both sizes (128×128 and 256×256), and PSNR was calculated as average for the three color channels, red, green , blue.

Complex problems need long time to be solved, with low efficiency and performance. Therefore, to overcome these drawbacks, the studies went toward the approaches of breaking the problem into independent parts, and treating each part individually in the way that each processing element can execute its part of the problem simultaneously with the others.Parallel processors are computer systems that consist of multiple processing units connected via some interconnection network and the software needed to make the processing units work together. Parallel processing is divided into three types; Shared, Distributed and Hybrid memory systems.In this paper, distributed memory systems addressed depending on client/servers principles, the network can contain any number of nodes; one of them is a client and the others are servers. The algorithms used here are capable of calculating the (Started, Terminated, Consumed -CPU and Total Execution- times and CPU usage) of servers and the Client's -CPU and total execution- times. This work addresses an improved approach for problem subdivision in balanced form and design flexible algorithms to communicate efficiently between client-side and servers-side in the way to overcome the problems of hardware networking components and message passing problems. We addressed Matrix-Algebra case-study to display the effect of balance load-division for this approach. The obtained results are checked and monitored by special programming-checking-subroutines through many testing-iterations and proved a high degree of accuracy. All of these algorithms implemented using Java Language.
