Inter-view 2D DWT is implemented in a separable approach by filtering the image rows followed by the image columns by using the 1D disparity compensated DWT. The red arrow shows the direction of the 1D DWT. (a) Extracted layer: 2 × 2 light field. (b) Transform coefficients following 1D disparity compensated DWT across each row. (c) Transform coefficients following 1D disparity compensated DWT across each column. Note that the background has been labeled grey and is outside the boundary of the layer.
