Table 1 Number of operations required of AW cost aggregation for every pixel, when using n × n support region size and d disparity range
From: Real-time stereo vision system using adaptive weight cost aggregation approach
| Â | Multiplication | Division | Addition | Shift |
|---|---|---|---|---|
Original algorithm | 3(n2 × d) | d | 2(n2 - 1) | 0 |
Omit weights of reference image | 2(n2 × d) | 0 | n2 - 1 | 0 |
+Dimensional separation | 4(n × d) | 0 | 2(n- 1) | 0 |
+Truncation of weight value | 0 | 0 | 2(n- 1) | 4(n × d) |
