PPT-Digital Image Processing

Image compression Introduction Image Compression It is the Art amp Science of reducing the amount of data required to represent an image It is the most useful and commercially successful technologies in the field of Digital Image Processing. Decimation or downsampling reduces the sampling rate whereas expansion or upsampling fol lowed by interpolation increases the sampling rate Some applications of multirate signal processing are Upsampling ie increasing the sampling frequency before D We have no digital cable boxes that will work on digital cable tv No digital cable box is available Digital cable descrambler and digital cable box will be available someday At this time no digital cable tv box is available Look for digital cable de Astrophotograpy. …..
