Question

2. Perform Arithmetic coding with five motion vector values (-2.-1,0, 1,2) for the probability of occurrence of each vector listed in the second column of the table 1. Each vector is assigned a subrange and entropy depending on the probability of occurrence. Determine the arithmetic tag word with encoding procedure.
