我在 android 上尝试了按位异或,但出现以下错误:
04-11 00:25:47.404: E/cv::error()(7370): OpenCV Error: Sizes of input arguments do not match (The operation is neither 'array op array' (where arrays have the same size and type), nor 'array op scalar', nor 'scalar op array') in void cv::binary_op(cv::InputArray, cv::InputArray, cv::OutputArray, cv::InputArray, void (* const*)(const uchar*, size_t, const uchar*, size_t, uchar*, size_t, cv::Size, void*), bool), file /home/reports/ci/slave/50-SDK/opencv/modules/core/src/arithm.cpp, line 1021
这是我的代码:
Mat temp1 = mRgba.submat(roi);
Mat temp2 = Mat.zeros(temp1.size(), CvType.CV_8UC1);
Core.bitwise_xor(temp1, temp2, temp1);
我还尝试通过以下方式实例化 temp1 和 temp2:
Mat temp1 = new Mat(height, width, CvType.CV_8UC1);
Mat temp2 = new Mat(height, width, CvType.CV_8UC1);
但仍然是同样的错误..
