A Review of Various Image Compression Techniques
نویسنده
چکیده
The overall objective of this paper is to review various image compression techniques. Image compression has become very important tool in digital image processing. The main objective of the compression is to reduce the amount or unwanted data while retaining the information in the image. The goal behind is to save the amount of memory required to save the image(s) or to utilize network bandwidth in efficient manner. Transform-based compression is extensively used for image compression. But transform based methods introduce blocking artifacts in the output image. The compression may also results in ringing artifacts around edges. The ringing artifacts are in general more difficult to characterize and remove than the block transform compression artifacts.

Compression can be done by lossy or lossless methods. The lossy methods have been used more widely than the lossless compression. Although, many methods for image compression have been proposed yet, the methods using intelligent skipping proper to the visual models has not been considered in the literature. Image inpainting refers to the application of sophisticated algorithms to replace lost o...
