本文介绍如何使用OpenCV将Mat对象转换为字节数组及从字节数组还原为Mat对象的方法。首先定义了一个名为matToBytes的函数，用于将Mat对象转换为字节数组。随后定义了名为bytesToMat的函数，该函数接收字节数组并将其转换回Mat对象。
byte * matToBytes(Mat image)
{
int size = image.total() * image.elemSize();
byte * bytes = new byte[size]; // you will have to delete[] that later
std::memcpy(bytes,image.data,size * sizeof(byte));
}
Mat bytesToMat(byte * bytes,int width,int height)
{
Mat image = Mat(height,width,CV_8UC3,bytes).clone(); // make a copy
return image;
}
{
int size = image.total() * image.elemSize();
byte * bytes = new byte[size]; // you will have to delete[] that later
std::memcpy(bytes,image.data,size * sizeof(byte));
}
Mat bytesToMat(byte * bytes,int width,int height)
{
Mat image = Mat(height,width,CV_8UC3,bytes).clone(); // make a copy
return image;
}
