2014-09-25 14:42:49 -0600 | asked a question | Object recognition routines. After writing several routines in C++ using SIFT and SURF and running examples found on websites, including yours, although they all run and "work" none do a good job of recognizing learned objects. Is there such a routine out there that does the following: Given a staged HD digital frame of an object (Called Object) with a distinct outline and unique features. Given a HD webcam. A Frame from the webcam (the Scene) is grabbed with the Object in the Scene. The Object is unobscured, " large enough", in a similar rotational position, The Object and the Object in the Scene are facing the camera similarly. The routine returns a indicator that gives the probability of the Object being in the Scene. The routine returns an indicator of the location of the Object in the scene. It must do it consistently without having to change parameters in the code. Is something like this available anywhere. I can't find or code it. Help, please. |

Is there some dependencies or relationships I am not addressing when defining pixels in the object and scene? Maybe some suggestions I need to address. |

2013-11-20 13:35:44 -0600 | commented answer | Pixcel values in 2 different frames always show to be the same. Thanks. Was hoping I didn't have to go from picture frame to matrix and back to picture frame to do pixcel operations. |
2013-11-19 18:28:35 -0600 | asked a question | Pixcel values in 2 different frames always show to be the same. I capture 2 different frames yet when I try to compare pixcel values between the 2 frames, they appear to be identical. I am probable misusing Vec3b. Please help an obvious novice. Thanks. |
2013-11-08 17:19:04 -0600 | asked a question | Reading pixels from 2 Mats & get the same data I am new to opencv. I am trying to read pixel values from the same row and column from 2 separate Mats called Mat frame and Mat frame1. My program shows them as always being the same value in Mat frame and Mat frame1 and that isn't true. Could you help me please? |
