Efficient Stereo Matching Based on Pervasive Guided Image Filtering

Figure 3

Performance comparison of error rates in the all-region of disparity maps using different schemes. These experiments were performed to verify the importance of using a step function (the same color convention as in Figure 2 is applied here).

(a) Color images selected from the benchmark (from left to right): Jadeplant, Motorcycle, Pipes, and PlaytableP
(b) Ground truth disparity maps
(c) Error rates in the all-region using the original FIF [21]
(d) Error rates in the all-region with the step function f(z) in applying FIF [21]
(e) Error rates in the all-region using PGIF(N)
