Hi, I've tried bitwise xor on android but I get the following error:
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
Here is my code:
Mat temp1 = mRgba.submat(roi);
Mat temp2 = Mat.zeros(temp1.size(), CvType.CV_8UC1);
Core.bitwise_xor(temp1, temp2, temp1);
I've also tried to instantiate temp1 and temp2 the following way:
Mat temp1 = new Mat(height, width, CvType.CV_8UC1);
Mat temp2 = new Mat(height, width, CvType.CV_8UC1);
But still the same error..
