In the field of robot vision
edge feature based stereo matching algorithm can reconstruct the targets with clear contours
which needs accurate and continuous target edges been extracted. In the paper
the smoothing filter operator was designed based on the discrete criteria of edge extraction and its correspondence optimal linear filter. Edge extraction was carried out incorporated the nonmaximum suppression and two thresholds techniques. The discrete criteria based multi-scale edge extraction method was studied with full use of the multi-scale character of the edge information. The detected multi-scale edges were synthesized to obtain the accurate and continuous single pixel wide edge. Then an edge feature based stereo matching algorithm was proposed to obtain 3D information of target. The experimental results demonstrate that the method can effectively suppress disturbance in outdoor environment and reconstruct target contour clearly. (2011) Trans Tech Publications.

The precision of FOG has highly effect on the servo system's final precision. In this paper
two filter methods has been researched in signal processing of FOG
smoothing filter method and Kalman filter based on ARMA model
in order to improve turn table servo control system's performance. To validate the effects of these two methods
three experiments have been made
which are filter examinations
dynamic experiments and Static experiments. The experiments reveal that these two kinds of filter methods are useful to filter the unknown noises and very effective to improve the precision of servo control system. 2010 IEEE.
