2015-03-30 09:37:51 -0600 | asked a question | Is it possible to check status of loading a big size file? Hello all, I am using the load function in opencv to load a big size file (about 64MB). It works well without error. However, when the application is loading the file, I cannot use any other task. Do we have any way to check that the file is loading? I want to show in the console that |

The GUI allows to automatically resize the control in GUI. It works for video displaying. However, I have problem when video is opening. When video is openning, I cannot click any control or minimize button in that GUI. I also cannot click or move that GUI in the sceen. If I want to close the GUI, I must You can download my source code at here (visual 2012+ opencv 2.4.10) |
2015-03-26 09:43:42 -0600 | commented answer | Replace background in video by opencv Thank Kbami and StevenPuttemans. For background changing, we can using MOG and GOG model, right? I found some tutorial of that problem at http://stackoverflow.com/questions/15..., Right? |
2015-03-26 00:15:00 -0600 | asked a question | Replace background in video by opencv I am looking for method and implementation to replace background in video. My goal looks like Youtube video. The author said that he used threshold value to extract background and replace them. However, I don't believed that threshold can acheived very nice result. Could you suggest to me any method that available in opencv for real time replacing background in opencv. Thank you in advance |
2015-03-25 01:01:21 -0600 | answered a question | Face detection and comparision The face detection looks well. However, If you want to compare (recognition), you must training the face first. You can use some database that is available such as AT. Let read that tutorial http://docs.opencv.org/modules/contri... |
2015-03-25 00:57:26 -0600 | commented answer | Real time head segmentation using opencv Could you share your source code to my email? It is very useful for my saving time. I want to compare that method and grabcut about both accuracy and computational time. Thank you so much. My email is [email protected] |
2015-03-24 08:06:45 -0600 | answered a question | Gender detection It depends on your problem. What is your expected accuracy? What is your time requirement? They have trade off between time and accuracy. High accuracy increases computational time. In my experiment, I choose 100 images. In which, 50 images for male and 50 images for female. Good luck |

2015-03-23 12:46:02 -0600 | asked a question | Real time head segmentation using opencv I am using opencv 2.410 to implement a project. My project allows to segment head from video sequence which get from camera. First, I detect the head region and then apply segmentation method for that ROI region. For high accurate segmentation, I have chosen Grabcut method. However, it is very slow. I only achieved about 2 frames/second (Although I used downsampling method). I have two questions: 1. Have any faster method than Grabcut which have similar accuracy? On other hands, Do we have any way to segment head region. 2. Could you see my code and give me some optimal way to make it faster? Thank you in advance (more) |
