How to improve the accuracy of points detected ? about javacpp-presets HOT 3 CLOSED

Which function are you using to detect points?

from javacpp-presets.

the same used by example:
// only gray scale
final IplImage input= cvCreateImage(cvGetSize(image), IPL_DEPTH_8U, 1);
cvCvtColor(image, imageBW, CV_BGR2GRAY);

BytePointer elem = cvGetSeqElem(rects, iface);
CvRect rect = new CvRect(elem);

            bbox[0] = rect.x();
            bbox[1] = rect.y();
            bbox[2] = rect.x() + rect.width();
            bbox[3] = rect.y() + rect.height();

            flandmark_detect(input, bbox, model, landmarks);

It looks like this is detecting corners, so we might be able to get subpixel accuracy by calling cvFindCornerSubPix() on the detected corners.
