This alternative provides some important advantages when working with mobile robots in dynamic environments. The idea of stereo and motion computation on grouped grey level regions may be compared to the work of Matas on maximally extremal regions , which has proved to be very effective. Firstly, through motion information it is easier to use correspondences than by grey level information of the frames. The results are also more accurate and robust. This is due to the instantaneous motion features, such as position, velocity, acceleration and direction of the diverse moving objects that move around the robot.
6) can be rewritten by the following equation, which is a level set evolution equation [2, 3]: du ( s ) = − µk s ∇u + (log P( I s | α o ) − log P( I s | α b ) ) ∇u , dt (7) where k= u xx y 2y − 2u y u x u xy + u yy u x2 (u x2 + u y2 ) 3 / 2 . The curve evolution is achieved by iterative calculation of level values u(s) using Eq. (7). In curve evolution, the stopping criterion is satisfied when the difference of ! the number of the pixel inside curve v in the successive iteration is less than a threshold value.
2 Analysis of the Straight Stretches in the Three-Dimensional Environment In this case, the walking of a robot through a straight-line corridor is simulated. The proper movement of the robot enables considering the static objects in the scenario as elements moving towards the cameras. Figure 3 shows the results of applying the algorithms to the straight stretch in the simulated three-dimensional environment. In frame 265, although in the input image the first door present in the straight stretches of the corridors does not appear any more, its presence is still under consideration in the permanency memory.
