Line 29: Applying the 1-D DWT analysis filterbank in dimension {{math\|N1}}, it is now split into two chunks of size {{math\| {{frac\|N1\|2}} × N2 × N3}}. Applying 1-D DWT in {{math\|N2}} dimension, each of these chunks is split into two more chunks of {{math\|{{frac\|N1\|2}} × {{frac\|N2\|2}} × N3}}. This repeated in 3-D gives a total of 8 chunks of size {{math\| {{frac\|N1\|2}} × {{frac\|N2\|2}} × {{frac\|N3\|2}}}}. The first chunk is passed via a low pass filter in each of these dimensions and the second one via high-pass.
