This paper presents an efficient image compression approach based on JPEG image compression. JPEG is the most frequently applied image compression technique in today‟s world. We have developed an application based on VB.NET for converting and compressing images in JPEG format. Using this application we finally propose a relation between image quality with the amount of image compression.

\It is my thesis that worthwhile improvements can be made to lossless image compression schemes, by considering the correlations between the spectral, temporal and interview aspects of image data, in extension to the spatial correlations that are traditionally exploited." Images are an important part of today's digital world. However, due to the large quantity of data needed to represent modern...

In this paper all basic image compression techniques have been discussed. The image compression techniques which are useful in their related areas are analyzed. Compression methods DCT and DWT recently used for image compression which gives better compression ratio. This review paper gives clear idea about basic compression techniques and method. Keywords— MDP, KLT, SIFT, S-PCA

This paper is aimed at analyzing the performance of three different state-of-the-art image compression schemes namely Embedded Zerotree Wavelet (EZW), Spatial-orientation Trees Wavelet (STW) and Set Partitioning in Hierarchical Trees (SPHIT). The paper analyses the compression schemes using X-ray image data such that the quality of the reconstructed image would be closely related to its origina...

In present Multimedia Computing era, compression of multimedia data has been highly significant. Digital Image, being a major part of multimedia data, requires effective compression mechanisms as well. During last few decades, there had been innovated numerous image compression techniquesmost of which achieve considerable compression ratio by taking the advantage of domain transformation. Very ...

Image compression is a necessary technique for image transmission in a channel. In this paper, it is aimed to improve efficiency and dealing with the performance evaluation of image compression techniques for various kinds of images from uncontrolled environments. The key special of this paper is, the image compression is carried out using wavelet based image compression and decomposition techn...

Image compression is an application of data compression that encodes the original image with few bits. The objective of image compression is to reduce irrelevance and redundancy of the image data in order to be able to store or transmit data in an efficient form. So image compression can reduce the transmit time over the network and increase the speed of transmission. In Lossless image compress...

Region of Interest based compression is an efficient method of compression for images with a particular part to be most significant. It is always a better choice to compress the ROI with lossless compression while the rest of image with lossy compression technique. This paper proposes lossless compression for medical image(ROI) and near lossless compression for the rest of the image. Image othe...

The image partitioning scheme in fractal image compression is one of the important aspect for enhancement of performance. In this paper, an adaptive quardtree partitioning scheme is proposed where the entire image is sub-divided recursively into four sub-images. The partitioning points are selected adaptively in a image context-dependent way instead of middle points of the image sides as in qua...
