模型转化Mat-〉XML

第一步：获取参数

其中为matlab语言

1.components 个数

NumComponents= length(model.rules{model.start})

ncom =length(model.rules{model.start});

 2.Numberof features这个固定， = 31，model文件中没有记录

 3.Score threshold= model.thresh

 第二步：获取每个component的 root filter，part filters，deformation filter

 1.对于每个component首先获取其中rootfilter的索引

 由model.start获取root filter的标号，分两种情况：

         for icom = 1:ncom %component个数

            rhs =model.rules{model.start}(icom).rhs;

            % assume the root filter is firston the rhs of the start rules

            if model.symbols(rhs(1)).type =='T'

              % handle case where there's nodeformation model for the root

              root =model.symbols(rhs(1)).filter;

            else

              % handle case where there is adeformation model for the root

              root =model.symbols(model.rules{rhs(1)}(layer).rhs).filter;

            end

         end

 2.在每个component内，获取part filter的个数，并获取每个part的参数

 icom =1:NumComponents

 npart =length(model.rules{model.start}(icom).rhs) -1 ;

%icom取值不同不影响这个结果，应该不同的part值一样

 for ipart= 2: npart+1

    irule =model.rules{model.start}(icom).rhs(ipart);

    filternum =model.symbols(model.rules{irule}.rhs).filter;

    %获取每个part的相关参数[dx,dy,ds]和penalty[dx dy dxx dyy]

    Vx =model.rules{model.start}(icom).anchor{ipart}(1)+1;

    Vy =model.rules{model.start}(icom).anchor{ipart}(2)+1;

    dx = model.rules{irule}.def.w(2);

    dy = model.rules{irule}.def.w(4);

    dxx = model.rules{irule}.def.w(1);

    dyy = model.rules{irule}.def.w(3);

end
