MODIFIED JPEG ALGORITHM USING A NOVEL DISCRETE SINE OF COSINE TRANSFORM (DSOCT)

Abstract

There are various representations of information to communicate with each other such as text, image, audio and video. In broadcasting any message, there are two ways to communicate. The first way is to record some information and transmit it through antenna. The second way is to transmit the live information through antenna. In both cases the size of the information is very necessary. In first case, we need more memory to store the information and takes more time to transmit the information. In second case, we would not require memory since there is no need of storage, but it takes more time to transmit the information. To avoid to occupy the more memory for holding information and to reduce the time taken to transmit the information, image compression is required. The first part of the paper deals with the existing JPEG Algorithm which uses Discrete Cosine Transform. The second part of the paper deals with the Modified JPEG Algorithm which uses Discrete Sine Transform and compare it with the JPEG Algorithm with Discrete Cosine Transform. The final part of the paper deals with the Modified JPEG Algorithm which uses Novel Discrete Sine of Cosine Transform and compare it with the JPEG Algorithm with Discrete Cosine Transform
