你好,我用你的指标算了一下uiqm和uciqe,发现指标非常的大。据我看过的论文,这两指标通常在2以内。
这是我算后的结果:
Average: uiqm=9.089692147135265 uciqe=4.310251438111393
不知什么原因。
您好,我不了解lab的范围是怎么定下来的?
您使用的是color.rgb2lab 得到的lab的界限好像是l属于0100,a和b属于-128127
但是还有的代码是用的cv2换的颜色空间,cv2默认把l,a,b都归一化到了0~255
但是论文中又没有提到这个问题,请问你是怎么理解的呢
nevaluate
第37行,conl = np.mean(isl[::top])-np.mean(sl[::top]),
应改为conl = np.mean(isl[:top])-np.mean(sl[:top])
::top是隔top个取一个的意思,:top才是取前top个的意思
您好,感谢您的代码。但是我用您的代码进行评价水下图像增强后的图片时,结果不合理。UIQM是0.7-0.8(正常是3+),而UCIQE是29-30(正常是零点几).这显然是不合理的,我用的就是PNG格式的图片,请问这是因为什么导致的呢?
