2017-05-08 11:48:30 -0600 | commented question | Detect object with Canny Edge detector I just updated my gradient. But, it only differs in the values of the edges.In this program, I want to get region for near focus ( flower object). Thank pro for suggesting. Hope to receive reply information. |

2017-05-08 11:03:41 -0600 | asked a question | Detect object with Canny Edge detector Hi guys, I am develop multi-focus application. Now, I can detect keypoint feature with ORB and Canny detect result. I want to get focus region with my result. But, I don't know how to get object. This is source image This is Canny detecttion result. And, I want to get flower object. Hope receive any idea or guide me develop it. Thanks every one read it. ====== update Gradient Map======= Gradient result for 2 image |

2017-01-24 02:50:14 -0600 | asked a question | DescriptorMatcher in OpenCV3 for Android Dear all, I am a newbie for developing with OpenCV and computer Vision, this is a first project i developed with OPENCV on Mobile - Android - used Android Studio. I can use many functions of OpenCV Library, but when I call DescriptoerMatcher in Java file, I miss errors, details code: //detect the key points detector.detect(inputMat1,keypoints1); detector.detect(inputMat2,keypoints2); //detect decriptor Mat descriptors1 = new Mat(); Mat descriptors2 = new Mat(); descriptorExtractor.compute(inputMat1,keypoints1,descriptors1); descriptorExtractor.compute(inputMat2,keypoints2,descriptors2); processedMat1 = new Mat(); processedMat2 = new Mat(); Imgproc.cvtColor(inputMat1,processedMat1,Imgproc.COLOR_RGBA2RGB); Imgproc.cvtColor(inputMat2,processedMat2, Imgproc.COLOR_RGBA2RGB); Features2d.drawKeypoints(processedMat1,keypoints1,processedMat1,new Scalar(255,255,0),4); Features2d.drawKeypoints(processedMat2,keypoints2,processedMat2,new Scalar(255,255,0),4); DescriptorMatcher descriptorMatcher = DescriptorMatcher.create(DescriptorMatcher.BRUTEFORCE_HAMMING); But the error is line create DescriptoerMatcher. Detailed of error: JNI DETECTED ERROR IN APPLICATION: use of invalid jobject 0x4 from long org.opencv.features2d.DescriptorMatcher.create_0(int) I trying research but now, I haven't found a issue and how to implement error. Hope received of any people. Thanks so much. |
