Consider the formula in image processing $R_D = 1- \frac{1}{C_R}$ where $C_R = \frac{n_1}{n_2}. \quad C_R$ is called as compression ratio $n_1$ and $n_2$ denotes the number of information carrying units in two datasets that represent the same information. In this situation $R_D$ is called as relative ____ of the first data set.

  1. Data Compression
  2. Data Redundancy
  3. Data Relation
  4. Data Representation
