先比較結構體引數是否一致,再用memcmp比較影象資料是否一致.

bool matIsEqual(const cv::Mat mat1, const cv::Mat mat2) {
	if (mat1.empty() && mat2.empty()) {
		return true;
	}
	if (mat1.cols != mat2.cols || mat1.rows != mat2.rows || mat1.dims != mat2.dims||
		mat1.channels()!=mat2.channels()) {
		return false;
	}
	if (mat1.size() != mat2.size() || mat1.channels() != mat2.channels() || mat1.type() != mat2.type()) {
		return false;
	}
	int nrOfElements1 = mat1.total()*mat1.elemSize();
	if (nrOfElements1 != mat2.total()*mat2.elemSize()) return false;
	bool lvRet = memcmp(mat1.data, mat2.data, nrOfElements1) == 0;
	return lvRet;
}
