2015-01-14 04:37:00 -0600 | asked a question | how can i read all frames? I have written some code to read a video and do some processing on it. total frames=1707 fps=30 I do processing on each frame but my code does it for only 804 frames. How can I do the processing for all frames? After processing 804 frames ,i see this text: this is a .avi video format. Can you please help me to solve this problem? I use windows 7,visual studio 2012,opencv 2.4.6 for processing this video file. my code: |

2014-02-13 05:34:06 -0600 | commented question | how i can add and load data file to train svm classifier? i use video file c:\happy_0014_1.mpg for test.i want to know add fg-net dataset to program.i have tow fg-net dataset:one of them consists video files and other consists images.i think that i should creat text file and copy dataset images.please help me |
2014-02-12 03:29:58 -0600 | asked a question | how i can add and load data file to train svm classifier? i read a pdf file that is use FG-NET dataset to train svm. FG-NET Facial Expression and Emotion Database consists of MPEG video files with spontaneous emotions recorded. Database contains examples gathered from 18 subjects ( 9 female and 9 male). Proposed system was trained with captured video frames in which the displayed emotion is very representative. The training set consists of 675 images of seven states neutral and emotional (surprise, fear, disgust, sadness, happiness and anger). inputdir , outputdir,path words that used in this c++ program ,how can i define inputdir,outputdir,path? how i can define path to load dataset for both train and test steps?(ex c:\feed\dataset...) i upload program at:http://rapidshare.com/share/15E45C30BB237A797F355EC82F09B8C1 |

2014-02-06 00:46:25 -0600 | asked a question | how i can load my data set to train classifier in svm? I work on the Facial Expression Recognition System.when i run program i see this error: C:\fakepath\error.jpg opencv error:Null pointer (invalid classifier cascade) in unknown function,file c:\slave\builds\WinstallerMegaPack\src\opencv\modules\objdetect\src\haar.cpp,line 1514 C:\slave\builds\WinstallerMegaPack\src\opencv\modules\objdetect\src\haar.cpp,line 1514: error:<-27> Invalid classifier cascade i think i can not load model correctly for training my system.i have FG-NET dataset to train my system but i do not know add this datasets to my program. What can I type instead of the line marked with stars? why use "type"?what is type? where is file that is contains model ?(that use in mt.loadmodel()) why we use "emo_svm_model.xml"? in the other part of my program I use the below code: What can I type instead of the line marked with stars? I can not do the training. Please help me to do training.i type multitrain class below:
i type function that use in multitrain class below:
