%% How to customize the namelist_*.txt file
% You can modify the object categories that will appear in the dataset by 
% editing the 'namelist_*.txt' file. 
% For example, if you want 'athlete' and 'spectator' be merged into a same category
% 'human'. The 'namelist_*.txt' should look like:
%      %%%%%%%%%%%
%      %salient objects
%      %%%%%%%%%%%
%      human,athlete,spectator 
%      ......
% After running LHIregulatenames(), the 'athlete' and 'spectator' will 
% merge into 'human', and share same color in the labelmap

% Another example, if your algorithms concerns about a certain category 
% inside the "less important objects" list (e.g. 'chair'),while 
% you have no interest on some categories inside the "salient objects" 
% such as 'window' 'light'. You can simply comment the line of 
% 'window' 'light' and uncomment the line of 'chair'. Then the 'chair' will 
% automatically appear among the object list when you do LHIregulatenames(), and
% 'window','light' will be categorized into 'other'.
%      %%%%%%%%%%%
%      %salient objects
%      %%%%%%%%%%%
%      .........
%      %light
%      %window 
%      ......   
%      %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%      %less important objects
%      % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%      .....
%      chair
%      %.....
% The SALIENCY of an object category is decided heuristicly by
% occuring frequency and occupied area of the category, which differs
% from case to case.

%% Show image

LHIdbshowimage(db,i,HOMEIMAGES);

%% Geometry
% show geometry of a certain image

%% Template
% % Queries for badminton category

db_part = LHIquery(badminton, 'object.parts.name', 'skeleton');
% display the parts with template ids
