Analysis of Various Image Compression Techniques

With the rapid development of digital technology in consumer electronics, the demand to preserve raw image data for further editing or repeated compression is increasing. Image compression is minimizing the size in bytes of an image without degrading the quality of the image to an unacceptable level. There are several different ways in which images can be compressed. This paper analyzes various image compression techniques. In addition, specific methods are presented illustrating the application of such techniques to the real-world images. We have presented various steps involved in the general procedure for compressing images. We provided the basics of image coding with a discussion of vector quantization and one of the main technique of wavelet compression under vector quantization. This analysis of various compression techniques provides knowledge in identifying the advantageous features and helps in choosing correct method for compression.
