% ---------------------------------------------------------------
%
% The last version of CVPR latex template has been developed by
% Paolo.Ienne@di.epfl.ch and awf@acm.org about 15 years ago. 
% The previous version suffer from several issues:
% 1. Authors needs several individual files: cvpr.sty, cvpr_eso.sty
%    eso-pic.sty.
% 2. For cvpr rebuttal another verison of cvpr.sty is required.
% 3. Several warnings exists due to depreiciated options.
%
% This style file is intended to be used as a single style file 
% that could help to fuild review, rebuttal and final files with
% a single style file.
% If you find any bug or have any further suggestions, please contact
% Ming-Ming Cheng (cmm@nankai.edu.cn).
% 
% Acknowledge: this file is modified from the the old cvpr template 
% files: cvpr.sty, cvpr_eso.sty, and eso-pic.sty.

% ---------------------------------------------------------------
%
% no guarantee is given that the format corresponds perfectly to
% IEEE 8.5" x 11" Proceedings, but most features should be ok.
%
% ---------------------------------------------------------------
% with LaTeX2e:
% =============
%
% use as
%   \documentclass[times,10pt,twocolumn]{article}
%   \usepackage{latex8}
%   \usepackage{times}
%
% ---------------------------------------------------------------

% with LaTeX 2.09:
% ================
%
% use as
%   \documentstyle[times,art10,twocolumn,latex8]{article}
%
% ---------------------------------------------------------------
% with both versions:
% ===================
%
% specify \cvprfinalcopy to emit the final camera-ready copy
%
% specify references as
%   \bibliographystyle{ieee}
%   \bibliography{...your files...}
