3D Photos - Fire Hydrant Wheel
This is the initial stereo pair as taken by my htc evo 3d android phone. The image size is 1920x1080 pixels.
This is the stereo pair after epipolar rectification (by er9b).
This is the depth map produced by dmag5 using the following parameters:
image 1 = ../image_l.png
image 2 = ../image_r.png
min disparity for image 1 = -27
max disparity for image 1 = 14
disparity map for image 1 = depthmap_l.jpg
disparity map for image 2 = depthmap_r.jpg
occluded pixel map for image 1 = occmap_l.jpg
occluded pixel map for image 2 = occmap_r.jpg
radius = 16
alpha = 0.9
truncation (color) = 30
truncation (gradient) = 10
epsilon = 255^2*10^-4
disparity tolerance = 0
radius to smooth occlusions = 9
sigma_space = 9
sigma_color = 25.5
downsampling factor = 1
That's a pretty decent depth map we've got here. I think we can improve it a tiny bit by using an edge preserving smoother like eps7.
This is the depth map produced by eps7 using the following parameters:
image to filter = ../depthmap_l.jpg
joint image = ../../image_l.png
sigma_s = 1000
sigma_r = 100
num_iterations = 3
filtered image = depthmap_l_eps7.jpg
