Software: Graphic, Media, Multimedia Arry Akhmad Arman School of Electrical Engineering and Informatics Institut Teknologi Bandung, Indonesia Email: arman@kupalima com arman@kupalima.com Website: http://www.kupalima.com Blog: http://kupalima.wordpress.com This course material can be downloaded at http://slideshare.net/kupalima Arry Akhmad Arman | School of Electrical Engineering and Informatics ITB | 2008
  • 2. Invention of WWW (World Wide Web) ( ) • The World Wide Web (commonly shortened to the Web) is a system of interlinked hypertext documents accessed via the Internet. With a Web browser, a user views Web pages that b b h may contain text, images, videos, and other multimedia and navigates between them using hyperlinks hyperlinks. • The World Wide Web was created in 1989 b B i i h scientist Si Ti by British i i Sir Tim Berners‐Lee, working at the European Tim Berners-Lee Organization for Nuclear Research weaves the Web for Everybody (CERN) in Geneva Switzerland and Geneva, Switzerland, released in 1992.

Focus on Computer Graphic (Image) Image Representation • Total number of Pixel pixels is (H x V) H (horizontal number of pixel) • Every pixel represented by – 1 bit (black and white) – 1 byte (greyscale) – 1 byte (256 color) – 2 byte (64K color) – 3 b t (16M color) byte l ) – more … Arry Akhmad Arman | School of Electrical Engineering and Informatics ITB | 2008 7
  • 8. Greyscale Image ( byte p p y g (1 y per pixel) ) • Image 500 x 400 pixel • Total number of pixel is 200.000 pixel • E h pixel represented b 1 b t Each i l t d by byte • Total image capacity 200.000 x 3 byte = 200.000 byte Pixel-2 Pixel-n = 1 byte Pixel-1 Arry Akhmad Arman | School of Electrical Engineering and Informatics ITB | 2008 8
  • 9. Color Image (true color, 3 byte per pixel) • Image 500 x 400 pixel • Total number of pixel is 200.000 pixel • Each pixel represented by 3 byte • Total image capacity 200.000 x 3 byte = 600 000 byte 600.000 Pixel-1 Pixel-2 Pixel-n = 1 byte Arry Akhmad Arman | School of Electrical Engineering and Informatics ITB | 2008 9
  • 10. Color vs Greyscale vs BW y Black and White Color Greyscale Arry Akhmad Arman | School of Electrical Engineering and Informatics ITB | 2008 10
  • 11. Black and White (1 bit p p ( per pixel) ) 8 pixels 8 pixels = 1 byte 8 pixels Greyscale Black & White Arry Akhmad Arman | School of Electrical Engineering and Informatics ITB | 2008 11
  • 12. Focus on Computer Graphic (Image) Image Compression • Lossy Compression: some information are loss, de‐compression result not same with original image. Example: JPEG • Lossless Compression: no information loss, de‐ compression result same with original image. Example: GIF, TIFF C Compression i ?!hasoas$^%& 823hiwef93 hnf*6867888 DeCompression Original, 600KB Compressed, <<600KB Arry Akhmad Arman | School of Electrical Engineering and Informatics ITB | 2008
