this method is that we can modify the noise bits in the image without affecting the quality and yield better compression ratio.
I. INTRODUCTION(cont.)
The advantage of this new technique is that the compression ratio is higher than reversible compression method and the image quality is not affected.
II. MATERIALS AND ETHODS
When an image is contaminated by noise, the correlation between pixels is degraded. As a result, the efficiency of image compression is decreased.
The signal bits contain image structural information. The noise bits are contaminated by noise.

involved in the picture can be drastically reduced by employing image compression techniques. The human eye is insensitive to a wide variety of information loss. The redundancies in images cannot be easily detected and certain minute details in pictures can also be eliminated while storing so as to reduce the number of pixels. These can be further incorporated while reconstructing the image for minimum error. This is the basic idea behind image compression. Most of the image compression techniques are said to be lossy as they reduce the information being stored.

ts the general law of data compression, which is to assign short codes to common events and long codes to rare events. Data compression is done by changing its representation from inefficient to efficient form.

The main aim of the field of data compression is of course to develop methods for better and better compression. Experience shows that fine tuning an algorithm to squeeze out the last remaining bits of redundancy from the data gives diminishing returns. Data compression has become so important that some researches have proposed the simplicity and power theory. Specifically it say..................[:=> Show Contents <=:]

wer generation is rapidly finding a prominence as a major part of power in the modern world. There are various problems associated with the tapping of Sun?s energy, such as movement of Sun. Researches has been going on to find new and efficient method to harness the solar power.

Commonly the solar panel is placed above the Earth?s surface facing the sun tilted at an angle of 450.But there is a problem, we can get maximum output from the panel only when the Sun comes perpendicular to the face of the panel. In late morning or afternoon, we cannot get maximum output from the panel. Thus for m..................[:=> Show Contents <=:]
