But eclipse doesn't recognize namespace cv or std. can anyone please help me? Btw, I'm using ubuntu 14.04. Thanks |

2015-03-23 03:39:45 -0600 | asked a question | Import Matlab Matrix to OpenCv Hi all, I'm new to C++ and OpenCv and I really appreciate your help. I'm trying to convert my Matlab codes to c++ using openCV. To verify my code I want to import my Matlab matices so I use this Matlab function to convert them to yml file: unction matlab2opencv( variable, fileName, flag) [rows, cols] = size(variable); % Beware of Matlab's linear indexing variable = variable'; % Write mode as default if ( ~exist('flag','var') ) flag = 'w'; end if ( ~exist(fileName,'file') || flag == 'w' ) % New file or write mode specified file = fopen( fileName, 'w'); fprintf( file, '%%YAML:1.0\n'); else % Append mode file = fopen( fileName, 'a'); end % Write variable header fprintf( file, ' %s: !!opencv-matrix\n', inputname(1)); fprintf( file, ' rows: %d\n', rows); fprintf( file, ' cols: %d\n', cols); fprintf( file, ' dt: f\n'); fprintf( file, ' data: [ '); % Write variable data for i=1:rowscols fprintf( file, '%.6f', variable(i)); if (i == rowscols), break, end fprintf( file, ', '); if mod(i+1,4) == 0 fprintf( file, '\n '); end end fprintf( file, ']\n'); fclose(file); Then using the following command I write to matrices in the yml function: varA = rand( 3, 6); varB = rand( 7, 2); matlab2opencv( varA, 'newStorageFile.yml'); matlab2opencv( varB, 'newStorageFile.yml', 'a'); % append mode passed by 'a' flag Then I use this c++ code to see the matrices in visual studio: but the output are empty matrices. Does anyone have any idea why? |
