Data Compression Unit 2 Pdf Code Videotelephony If the resources are limited and we do not require absolute integrity of the data, we can improve the amount of compression by accepting a certain degree of loss during the compression process. performance measures are necessary to determine the efficiency of our lossy compression schemes.

What is data compression? data compression is the representation of an information source (e.g. a data file, a speech signal, an image, or a video signal) as accurately as possible using the fewest number of bits. Data compression data compression is also referred to as bit rate reduction or source coding. this technique is used to reduce the size of large files. the advantage of data compression is that it helps us save our disk space and time in the data transmission. there are mainly two types of data compression techniques. For complex images, huffman coding alone will typically reduce the file by 10 to 50% (1.1:1 to 1.5:1), but this ratio can be improved to 2:1 or 3:1 by pre processing for irrelevant information removal. Course notes on reversible and irreversible techniques for compressing data files.
