NewROC

本函数由于图像中目标检测算法的评价，依据的是ROC曲线
本函数可以绘制ROC曲线，并计算相应的评价指标，如auc, sensitivity, specificity 等

---

example:

threshold=0:0.01:1;
groundtruth = imread('manual.tif');
groundtruth = double(groundtruth)/255;
detecResoult = imread('detec.png');
detecResoult = double(detecResoult)/255;
[auc, IoU, acc, se, sp, pr, MedNR] = newroc(groundtruth, detecResoult, threshold);

Note:

   1.本函数用到gpu进行加速
   2.目标检测的评价参数不局限于当前这几种，你可根据需要自行增减
