javacv

I'm using FFmpegFrameRecorder for video broadcast.Problem is audio comes faster than video frame.I'm using following code but unable to produce complete video there is problem in audio video timestamp. Java Code: import static com.googlecode.javacv.cpp.opencv_core.IPL_DEPTH_8U; import java.io.IOException; import java.nio.ShortBuffer; import android.app.Activity; import android.content.Context; import android.content.pm.ActivityInfo; import android.graphics.Bitmap; import android.graphics.Canvas; import android.hardware.Camera; import android.hardware.Camera.PreviewCallback; import android

i want detect the important ROI Element in a picture. (i want to get the position) I've tested a reverted SeamCarving-Method . I hoped, that the most importand Area in a picture have the most energylevel. I've generated one vertical and one horizontal Seam and took the intersection. But this method don't seem to be perfect. Some examples: good detection: good detection http://img713.imageshack.us/img713/2928/seamcastle.jpg good detection http://img39.imageshack.us/img39/9584/seamente.jpg good detection http://img193.imageshack.us/img193/2693/seamwuffi.jpg near aceptable; good detection http:/

I'm trying to access Pixel by Pixel of an IplImage. Im using Java and Processing, and sometimes I need to access pixel by pixel. I've done this so far, but I don't know what's wrong: public IplImage PImageToIplImage(PImage imageSrc) { IplImage imageDst; if(imageSrc.format==RGB) { imageDst = IplImage.create(imageSrc.width, imageSrc.height, IPL_DEPTH_8U, 3); ByteBuffer imagePixels=imageDst.getByteBuffer(); int locPImage, locIplImage, x, y; for(y=0; y<imageSrc.height; y++) for(x=0; x<imageSrc.width; x++) { locPImage = x + y * width; locIplImage=y*imageDst.widthStep()+3*x; imagePixels.put

I'm developing a shape identification project using JavaCV and I have found some OpenCV code to identify U shapes in a particular image. I have tried to convert it into JavaCV but it doesn't give the same output. Can you please help me to convert this OpenCV code into JavaCV? This is the OpenCV code: import cv2 import numpy as np img = cv2.imread('sofud.jpg') gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY) ret,thresh = cv2.threshold(gray,127,255,1) contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE) for cnt in contours: x,y,w,h = cv2.boundingRect(cnt) if 10 < w

Could someone tell me where I'm doing wrong? These are the steps that I have followed: Downloaded the adt-bundle-windows from android developer website Created a new project and a libs/armeabi folder Extract all the *.so files from javacv-android-arm.jar, opencv-2.4.3-android-arm.zip, and ffmpeg-1.0-android-arm.zip directly into the newly created "libs/armeabi" folder, without creating any new subdirectories. (A part that I don't understand is "Extract all the *.so files from javacv-android-arm.jar" , I simply inserted the javacv-android-arm.jar file inside libs/armeabi folder) Navigated to

I would like to use some blob detection in my application which is written in Java and thus using JavaCV instead of OpenCV . I found many classes like: SimpleBlobDetector , CvBlobDetector , CvBlob , ... but I can't find any tutorial or demo/example code to use these in Java. Could anyone please tell me how to use these as I can't figure it out and there's no good documentation for them. Thanks! happyburnout I am just in this moment working on the same problem and have a first solution. There's a lot of approaches out there but unfortunately most of them are ugly and slow. My main goal to this
