2014-04-20 15:52:12 -0600 | asked a question | Change the color of a string text with createTrackbar Hi, i have created a GUI with a gray Background, three Trackbars and a Text. I have searched in Opencv wiki and finding this: createTrackbar but it is changing the color of an image not a string. Must i convert the string by calling the callback for trackbar?

2013-08-07 14:27:05 -0600 | asked a question | How can i test the face detection? Hey, how can i test the face detection in a Laptop? the people this question a negative review, "Have their boredom"? |
2013-07-30 11:18:26 -0600 | asked a question | What is the Difference from Face Detection from an image and from a Camera Hey, i write a documenting over the Face Detection from a Video and Face Recognation using eigenface from a video. I have finding many of documantations over face detection from a image. And Face Recognition using eigenfaces from a image. My question is: If i detect or recognize faces from camera: the camera take a photo and save this in "vectors" or in a xml file too like detect face and recognize face from a image? best regards Adrianos |
2013-05-21 14:19:24 -0600 | asked a question | Face Detection & Face Recognition using Opencv with C++ My Project is to write a Program that recognize faces with Video Camera and compare the recognized Face if the recognized face in database. If it not in Database send Email. I read in google the face detection and face recognition from OpenCV. Face detection and Face recognition: learns a subspace for each person and when i input a new image it measures the distance to all subspaces it has previously learned and chooses the nearest one. My Question is how can i sort and check that the image is too far from all learned subspaces. Also check the image is the same in the database: I should realise that with OpenCV. |

I have asked at the weekend this question on this forum and became a answer: http://answers.opencv.org/question/11552/how-to-start-to-program-face-recognition/ My answer is now: I have a OpenCV code that started my Webcam. Also can I use(insert) the same to my Webcam start code the function recognition, detection, train and to convert the grayscale the following code? Thanks |

This programm must do: If the face not in database send a sms to user. I have researched in internet that i can use for face recognation haarcascade...xml files or eigenface algorithm. What ist better eigenface or haarcascade? How can i start to write this program? I use the System Linux and i have installed the OpenCV-Libraries and i can use OpenCV-Libraries with CodeBlocks. Please help me with to write this project. |
