Shape recovery demo - right click to see next example; hit "return" key or use mouse to rotate the original or recovered shape. To exit, press ESC. The first six examples involve the same original shape recovered from different 2D images. The recovered 3D shape is roughly the same for all 2D images of the shape. Note that the entire 3D shape is recovered (both the front, visible, surfaces and the back, invisible ones), even though the model was given a 2D image from which the hidden edges were removed. The demo includes three different 3D shapes, six 2D images for each. The last object is a chair. The 3D chair was represented by 3D points and recovered from the 2D images of the points. In all examples, the model was given the contours, as well as the information about which features are symmetric in 3D space and which contours are planar in 3D space.

Shape recovery demo - image segmentation by hand - instructions as above. Contours on the 2D image were extracted by hand and the model was given information about which features are symmetric in 3D space and which contours are planar in 3D space. Press "c" to toggle contours and "i" to toggle image. The "chair" was recovered from six different 2D images. cknowledgment: The demo is prepared by Yunfeng Li.

Shape from binocular disparity - This applet demonstrates the effect of visual and oculomotor noise (error) on 3D shape reconstruction, when this reconstruction is based solely on visual and oculomotor information.
