2013-06-20 01:49:50 -0600 | asked a question | Why does the image break when converted to byte[]? (takePicture with Opencv on Android) I have an project that used Camera and Opencv. I take picture and crop image with OpenCv. After I have a Mat file to convert Jpeg for send byte[] data to Activity. Mat to Bitmap Bitmap to byte[] On Activity , But this image is not same with I cropped. This is like 16bit color... If I direct send Bitmap to activity and set ImageBitmap, this is good. Why does the image break when it's converted to byte[]? |

2013-05-24 01:26:36 -0600 | answered a question | how can I build and use only highgui-imgproc-core modules on Android? I solved my problem. First you need download source code from here. After you delete codes that not need from modules and those used include folders files. After build with /Android/scripts... |
2013-05-24 01:19:36 -0600 | asked a question | Manually set buffer was too small! Android Camera takePicture is using Previews small buffer I am developing a project using OPENCV. I have some process on onCameraFrame. While it shows previews, user can take a photo. But in some devices, I take an error after called takePicture(...) method. I set manually picture and preview sizes, picture is bigger than preview. What should I do? E/Camera-JNI(11783): Manually set buffer was too small! Expected 539380 bytes, but got 460800! This buffer's size is my frame size, 460800. I logged frame size at onCameraFrame . Every frame's sizes are 460800. As far as I understand, takePicture tries to use previews buffer. And theirs sizes are different. |

2013-05-16 01:46:10 -0600 | answered a question | static initialization And multipleAPK without Jni code I decided to use empty jni that defines arm for filtering. |
2013-04-24 01:52:08 -0600 | commented answer | Reducing Android package OpenCV Manager cant be answer for this question. Anyway to lower libopencv_java.so's file size? I think, this file has all modules. |

2013-04-22 05:50:41 -0600 | asked a question | static initialization And multipleAPK without Jni code I use Opencv with Android Library Project SDK. I need create multiple-apk each CPU. But My code has no JNI part.(no Apllication.mk) And i can't filter CPU on AndroidManifest. How should I do? |
2013-04-22 05:43:21 -0600 | asked a question | how can I build and use only highgui-imgproc-core modules on Android? Hi, I use opencv library with static initialization. So SDK uploads every modules in APK. and Apk size is min 13 mb for one CPU type. But I use only three module from opencv. How can I crop library?? is it possible? |

2013-04-02 06:59:40 -0600 | asked a question | OpenCVManager couldn't built Hi, I need to use opencv library thats includes what opensvmanager does. I am newbea at NDK and OpenCv. Which steps should I follow?? -------------UPDATED---------- I learnt after research, I thought that manager sense CPU version and dowload its .so package. And use it with a interface. BUT there are alot of APK for every CPUs :) and playstore filters them.:) I decided publish more than one APK. ----irrelevant ----- I can't build OpenCVEngine. when I want to build .cpp codes with ndk-build |
