Stereo Disparity

3D reconstruction can be done based on depth information obtained from a pair of cameras. Stereo disparity map basically tells us the distance between each point in image and the camera.


Optical Flow

Optical Flow gives us information related to how the pixels move between images taken at two different points in time. Color coding can be used to display the movement direction.



Pixels of the image can be segmented into meaningful groups. Segmented images can be used for object detection, grasping etc.
