我正在开发一个程序来检测从高分辨率相机拍摄的图像中的皱纹。 目前该项目正处于起步阶段。到目前为止,我已执行了以下步骤:
以下是相同的代码:
package Wrinkle.Detection;
import java.util.ArrayList;
import java.util.List;
import org.opencv.core.Core;
import org.opencv.core.CvType;
import org.opencv.core.Mat;
import org.opencv.core.MatOfPoint;
import org.opencv.core.Scalar;
import org.opencv.core.Size;
import org.opencv.highgui.Highgui;
import org.opencv.imgproc.Imgproc;
public class DetectWrinkle {
private Mat sourceImage;
private Mat destinationImage;
private Mat thresh;
public void detectUsingThresh(String filename) {
sourceImage = Highgui.imread(filename, Highgui.CV_LOAD_IMAGE_GRAYSCALE);
//Contrast
Mat contrast = new Mat(sourceImage.rows(), sourceImage.cols(), sourceImage.type());
Imgproc.equalizeHist(sourceImage, contrast);
Highgui.imwrite("wrinkle_contrast.jpg", contrast);
//Remove Noise
destinationImage = new Mat(contrast.rows(), contrast.cols(), contrast.type());
Imgproc.GaussianBlur(contrast, destinationImage,new Size(31,31), 0);
Highgui.imwrite("wrinkle_Blur.jpg", destinationImage);
//Apply Adaptive threshold
thresh = new Mat();
Imgproc.adaptiveThreshold(destinationImage, thresh, 255, Imgproc.ADAPTIVE_THRESH_GAUSSIAN_C, Imgproc.THRESH_BINARY_INV, 99, 10);
Highgui.imwrite("wrinkle_threshold.jpg", thresh);
// dilation
Mat element1 = Imgproc.getStructuringElement(Imgproc.MORPH_RECT, new Size(2*3+1, 2*6+1));
Imgproc.dilate(thresh, thresh, element1);
Highgui.imwrite("wrinkle_thresh_dilation.jpg", thresh);
//Find contours
List<MatOfPoint> contours = new ArrayList<MatOfPoint>();
Mat image32S = new Mat();
Mat threshClone = thresh.clone();
threshClone.convertTo(image32S, CvType.CV_32SC1);
Imgproc.findContours(image32S, contours, new Mat(), Imgproc.RETR_FLOODFILL,Imgproc.CHAIN_APPROX_SIMPLE);
//Find contours with smaller area and color them to black (removing furhter noise)
Imgproc.cvtColor(thresh, thresh, Imgproc.COLOR_GRAY2BGR);
for (int c=0; c<contours.size(); c++) {
double value = Imgproc.contourArea(contours.get(c));
if(value<500){
Imgproc.drawContours(thresh, contours, c, new Scalar(0, 0, 0), -1);
}
}
Highgui.imwrite("wrinkle_contour_fill.jpg", thresh);
}
public static void main(String[] args) {
DetectWrinkle dw = new DetectWrinkle();
System.loadLibrary( Core.NATIVE_LIBRARY_NAME );
String imagefile = "wrinkle_guo (1).bmp";
dw.detectUsingThresh(imagefile);
}
}
问题: 从图像中显示的结果可以看出,皮肤上的单个皱纹被分解成单独的小元素。在这里,我试图通过使用扩张来连接这些元素以显示完整的皱纹。一旦完成,我通过首先检测轮廓,计算轮廓的面积,然后去除面积小于特定值的轮廓来消除噪音。
然而,这并没有给我一个合适的结果,所以我觉得可以有更好的方法来加入破碎的皱纹元素。请帮我解决这个问题。
请原谅我这个问题有什么问题,因为我真的需要一个解决方案而且我是新手。
