signature and voice recognition

该程序完成的是通过使用所提供的链码（一种方向码）来画出链码所表示的轮廓。所画轮廓在原图上是黑色的线。(the code is used for draw the outline of the region of interest which is show by the chaincode)

Erasure correction achieved by two errors-only decoding passes using the Euclidean algorithm. Any (valid) code length can be input. (Erasure correction achieved by two errors- only decoding passes using the Euclidean algo rithm. Any (valid) code length can be input.)

This paper describes different power quality problems in distribution systems and their solutions with power electronics based equipment. Shunt, hybrid and series active power filters are described showing their compensation characteristics and principles of operation. Different power circuits topologies and control scheme for each type of active power filter are analyzed. The compensation characteristics of each topology with the respective control scheme are proved by simulation and experimentally.
