Hi I'm new to OpenCV in Android. I'm trying to covert a C++ code into Java. I've been stucked in some point that I cannot continue.
std::vector<cv::Vec4i> lines;
cv::HoughLinesP(bw, lines, 1, CV_PI/180, 70, 30, 10);
// Expand the lines
for (int i = 0; i < lines.size(); i++)
{
cv::Vec4i v = lines[i];
lines[i][0] = 0;
lines[i][1] = ((float)v[1] - v[3]) / (v[0] - v[2]) * -v[0] + v[1];
lines[i][2] = src.cols;
lines[i][3] = ((float)v[1] - v[3]) / (v[0] - v[2]) * (src.cols - v[2]) + v[3];
}
half way I converted.. upto th TODO mark.
MatOfInt4 lines= new MatOfInt4(); Imgproc.HoughLinesP(bw, lines, 1, Math.PI/180, 70, 30, 10);
int[] lineArray = lines.toArray();
// Expand the lines
//TODO
for (int i = 0; i < lineArray.length; i++)
{
int v = lineArray[i];
lines.[i][0] = 0;
lines[i][1] = ((float)v[1] - v[3]) / (v[0] - v[2]) * -v[0] + v[1];
lines[i][2] = src.cols();
lines[i][3] = ((float)v[1] - v[3]) / (v[0] - v[2]) * (src.cols() - v[2]) + v[3];
}
which I'm confused is inside the for loop. when converted lines in to a Array it gives a int array. But inside the for loop again v is defined which should be a array. I didn't get this point. Can anybody please help me to get through this. Thank you in advance.
