A Survey of Various Data Compression Techniques
نویسنده
چکیده
This paper is a survey of various methods of data compression. When the computer age came about in the 1940’s, storage space became an issue. Data compression was the answer to that problem. The compression process takes an original data set and reduces its size by taking out unnecessary data. There are two main types of compression, lossy and lossless. This paper will deal exclusively with lossy compression. So, through the compression/decompression algorithm, some data from the original file is deleted and not recovered. There are many methods of compression, and this paper will go into depth about compression using Fourier Transformations and Wavelet Compression. Each of these methods has strengths and weaknesses in regards to different types of file; the paper will also cover those aspects of the two methods.
