Supports the transport of large images and animation (video) with high resolution
|
Eliminates redundant or less critical information
-
Spatial redundancy: values of neighboring pixels are strongly correlated
-
Spectral redundancy: the spectral values for the same pixel location are correlated
-
Temporal redundancy: frames show very little change in the sequence
|
|
Decreases the time and cost of transmission and storage requirements
|
Investigation of several image compression technologies
-
JPEG - leading standard, JBIG, Fractal, Wavelet - most promising
|
|
Power of wavelet-based methods - high quality, fast encoding / decoding, solid mathematical background
|
|
Wavelet compression is represented by the weighted sum of basis functions together with quantization and coding
