Progress on the online Pattern Recognition Yutie Liang, December meeting 2) adaptive Hough transform method ; 3) inclusion of the Mvd hits; Determination of the Radius ( = P  of the track) and center of Helix : Results on multitrack event, no Mixing for the moment; P  resolution = 3.1 % at 1 GeV/c at the PR level 1)conformal transformation for the Stt drift circles; use of the tangents to the drift circles to fill the Hough plot ;
