2015-04-07 19:48:11 -0600 | asked a question | What happens if there's not enough key points to match? Given two mat: I want to know if I do a Flann match against these two descriptors, what will happen if they have different number of descriptors in them? For what I experienced, it seems the number of matches will always be the same as the number of descriptors in |

2015-03-02 03:55:13 -0600 | asked a question | OpenCV 2.4 static lib relies on opencv_ffmpeg*.dll on Windows I want to compile a simple C program which I would like to statically link to opencv*.lib files. I am doing thin on Windows 64bit, with VS 2013. I have included the will fail, and will return false. But no exception of any kind is thrown. I noticed if I put my executable under It seems to me that the static lib is dynamically linking to this ffmpeg DLL. So even my program can run without DLLs from opencv, I still need to satisfy the dependencies of the static lib, which is a dynamic lib...so complicate. |

2014-04-14 23:44:51 -0600 | asked a question | How to cluster a batch of images? I have a batch of images, say the frontal photo of dogs and cats. I want to find a way to cluster these images into different classes. I don't want to use Cascade classifier, because some of the objects are unknown, and Cascade will only tell me it is unknown, but cannot help me to put them into categories. I tried to use kmeans, but I don't know how to create my sample data set. I tried to reshape an image into a row, each element is the grey scale of a pixel. Then I created a Mat with each row filled the image as before. So, it looks like: I fed this Mat to kmeans, The output labels.size() is same as my input sample numbers...:( Apparently it doesn't work. Am I working at the wrong direction? |
