Telephony on ISDN lines), and H. Testing between various compression types would be highly recommended. resize((160,300),Image. In addition, math is used in the global positioning system, for transmitting messages when d In the world of printing, TIF (Tagged Image File) format is widely used for its high-quality image resolution and lossless compression. Y Statistics in computer science are used for a number of things, including data mining, data compression and speech recognition. Open CV allows compression using a compression attribute, which can be set between 0 to 9 to vary the compression. save(filename='result. While our Method gave an output compressed image of 780 kb with minimal loss of data, existing online web services such as a short pixel gave an output of 980 kb. Other areas where statistics are use in computer sci Math is used in astronomy to calculate routes for satellites, rockets and space probes.
