Question

我是openCV概念的新秀，所以如果我的问题很愚蠢，请原谅我。实际上，我正在尝试使用Photo.fastNlMeansDenoisingColored()方法，但是我不明白为什么会这样错误。

代码：

Mat tmp = new Mat (bitmap.getWidth(), bitmap.getHeight(), CvType.CV_8UC1);

            Utils.bitmapToMat(bitmap, tmp);

            Photo.fastNlMeansDenoisingColored(tmp,tmp, 10, 10, 7, 21);


            Utils.matToBitmap(tmp,bitmap);

错误：

CvException [org.opencv.core.CvException: cv::Exception: /hdd2/buildbot/slaves/slave_ardbeg1/50-SDK/opencv/modules/photo/src/denoising.cpp:91: error: (-5) Type of input image should be CV_8UC3! in function void cv::fastNlMeansDenoisingColored(cv::InputArray, cv::OutputArray, float, float, int, int)

Answer 1

下载native libs并将它们放在您的result = year.concat(month).concat(suffix);目录中。

Answer 2

我已经通过将openCV库从2.x更新到3.0解决了我的问题

为什么openCV的fastNlMeansDenoisingColored（）提供了错误？
