#3Transform CodingzWhy transform Coding?zPurpose of transformation is to convert the data into a form where compression is easier. This transformation will transform the pixels which are correlated into a representation where they are decorrelated. The new values are usually smaller on average than the original values. The net effect is to reduce the redundancy of representation.zFor lossy compression, the transform coefficients can now be quantized according to their statistical properties, producing a much compressed representation of the original image data.
