Algorithm A4: 1D & 2D Filtered Dataset Compression.

Data: filtered_dataset, ascii_diccionary(customised), pair, char_diccionary  Result: compressed_dataset  compressed_dataset ← empty_array();  nt ← number_of_rows();  pair ← empty_array();  char ← empty_array();  for n in range(0,nt) do    FD ← filtered_dataset[n];    D ← ascii_diccionary;    C ← char diccionary;    for i in range(FD) do      append FD[i] − FD[i + 1] to pair;      if C.has_key(FD[i]) then     append C[i] to compressed_dataset;     if D.has_key(pair) then      append D[pair] to compressed_dataset;     else      append pair to compressed_data;    end.    else    echo “error message”    end       end  end
