2016-04-03 16:41:11 -0600 | commented question | Object detection using edge matching on android I used ORB for the detection. The items are kitchen objects such as fork, spoon, plate etc. I used edges because I need to ignore the background. I tried to do a regular matching and it doesn't work on different backgrounds or lighting conditions. Edges takes these factors out of the equation - that's why I tried it. Also, I tried to show the matches and for some reason nothing showed. |
2016-04-03 14:52:46 -0600 | asked a question | Object detection using edge matching on android Hello, I'm having some problem with finding objects in the camera frame using edges or contours (in order to dismiss the background of the object) in android platform, I've tried to find keypoints in the Canny results of both the template image and the frame, and then matching them, but it doesn't work as I expected. Is there a better way of doing it? If not please help me figure out what I'm missing. Applying Canny on the reference image and finding keypoints: Applying Cany on the frame and matching: After that a function is called to find the corners of the object: (more) |

2016-02-11 12:00:58 -0600 | commented question | Effective multiple object detection with a small data set Hi, thanks for your quick response. In my dattabase I keep the name of the object with it's images, so connecting between an image and it's name is an easy task. I thought that detection might be easier to perform, and thats why I wrote detection instide of recognition. As for the accuracy, I need it to be as high as possible on any object in the kitchen. Do you think Bag of Words is the best method to use here? Thanks again! |
2016-02-11 07:43:36 -0600 | asked a question | Effective multiple object detection with a small data set Hello, I want to detect objects according to images from a database filled by the user, with a maximum amount of 6 images(for 6 different angles). This amount is not enough for building a classifier, but I still need to be able to detect the objects in different backgrounds, different light conditions etc, in real time. I also need to detect multiple objects in every frame and be able to find a relation between the detected objects (for example: Cup on Table). How can I perform this kind of detection when I only have a small data set that I can't control? How sould I apply it on the other objects without increasing the response time? And How could I recognize the relation between them? Thank you. |
