Example 1 with Rect

use of org.opencv.core.Rect in project kifu-recorder by leonardost.

the class CornerDetector method getRegionOfInterestAround.

private Mat getRegionOfInterestAround(Corner corner, Mat image) {
    int x = corner.getX() - RADIUS_OF_REGION_OF_INTEREST > 0 ? corner.getX() - RADIUS_OF_REGION_OF_INTEREST : 0;
    int y = corner.getY() - RADIUS_OF_REGION_OF_INTEREST > 0 ? corner.getY() - RADIUS_OF_REGION_OF_INTEREST : 0;
    int w = x + 2 * RADIUS_OF_REGION_OF_INTEREST < image.cols() ? 2 * RADIUS_OF_REGION_OF_INTEREST : image.cols() - x;
    int h = y + 2 * RADIUS_OF_REGION_OF_INTEREST < image.rows() ? 2 * RADIUS_OF_REGION_OF_INTEREST : image.rows() - y;
    System.out.println("ROI: (x = " + x + ", y = " + y + ", w = " + w + ", h = " + h + ")");

    if (newFrame == null || newFrame.cols() != sourceFrame.cols() || newFrame.rows() != sourceFrame.rows()) {
        newFrame = sourceFrame.clone();
        perspectiveMultiplier = sourceFrame.cols() / 320;
        if (perspectiveMultiplier < 1)
            perspectiveMultiplier = 1;
    }
    newFrame.setTo(new Scalar(0, 0, 0));
