deprecated -- Light Field Toolbox v0.2 -- v0.3 now available



26 Apr 2013 (Updated )

A set of tools for working with light field (aka plenoptic) imagery in Matlab

LFFindLytroPartnerFile( OrigFilename, PartnerFilenameExtension )
% LFFindLytroPartnerFile - Finds metadata / raw data file partner for Lytro white images
% Usage: 
%   PartnerFilename = LFFindLytroPartnerFile( OrigFilename, PartnerFilenameExtension )
% The LF Reader tool prepends filenames extracted from LFP storage files, complicating .txt / .raw
% file association as the prefix can vary between two files in a pair. This function finds a file's
% partner based on a known filename pattern (using underscores to separate the base filename), and a
% know partner filename extension. Note this is set up to work specifically with the naming
% conventions used by the LFP Reader tool.
% Inputs:
%   OrigFilename is the known filename
%   PartnerFilenameExtension is the extension of the file to find
% Output:
%   PartnerFilename is the name of the first file found matching the specified extension
% See also:  LFUtilProcessWhiteImages, LFUtilProcessCalibrations
