00006 % If you want to pass in an aray of flags for windows you want checked,
00007 % and for values you want saved, call it with optional arguments:
00008 % [boxes, detects, n, index_array, output_values] = mpisearchMex(ci, img, get_detects, do_simplify, offset, index_array, output_values)%
00009 %
00010 % OUTPUTS
00011 %  boxes:       Face locations
00012 %  detects:     Actual patches of image that were detected
00013 %  n:           number of patches classified
00014 %  index_array: Array corresponding to windows that may or may not be checked
00015 %  output_values: Array holding output values of classifier for each window.
00016 %
00017 % INPUTS:
00018 %  ci:              classifier info sruct.  If it is 0, the built-in weights will be used
00019 %  img:             the image
00020 %  do_simplify:     whether or not to collapse overlapping boxes
00021 %  max_num_detects: maximum number of detected image patches to be returned
00022 %  box:             flag if you want actual boxes returned or not
00023 %  index_array:     Array corresponding to windows that may or may not be checked
00024 %  output_values:   Array holding output values of classifier for each window.
00025 %
00026 % NOTE: index_array and output_values MUST be the same variable, which
00027 % MUST have already been allocated using mp_makeindex.
