2013-12-05 10:53:56 -0600 | asked a question | Homography for set of trainimages How can I use findhomography()and perspectiveTransform() methods in the case where you have keypoints obtained from the trainset of images. following is my code.
One quick dirty solution would be to put this entire part of code in a forloop for all the images in training set and perform homography if the number of good matches is greater than 4 .but that would be very ineffective in terms of performance since i plan to use this code for the JNI part of android project im working on. Can anyone please guide me on how do the perspective transform and draw a rectangle around the detected object or suggest any better methods of doing it.(so far in my search through internet,i could only find 1 to 1 image matching and then draw homography for the detected object) |

2013-11-15 04:36:57 -0600 | asked a question | Training Kd tree for object detection android I am working on real time object recognition using Opancv4android, i am able to detect, extract feature points using ORB detector and descriptor extractor from the image i capture using camera . Now, i want to build a Kdtree and train them with these feature points and later i match these feature points in the tree with feature points detected by the camera in real time and recognizance the object . Please help me on how do i go about building a KD tree in opencv or any pointers or references/tutorials on KDtree for opencv will be very helpful. |
