具有自己的类的类型的2D数组的好选择

Question

I'm doing image processing and I'd like to make an own object out of every pixel, containing stuff like position, ID, value, etc. Now in post-processing I need to access some of these specific objects around a currently selected Pixel.

The easiest way I could imagine would be a storage like

PixelClass[image.rows][image.cols]

returning a Pointer of the object at a position. But I'm afraid this won't be easy to handle. Are there any nice alternatives, to easily access the generated objects by their position (ie: x,y) in C++?

EDIT: I forgot access needs to be as fast as possible, for real-time applications

Thanks for any advice

您可以提供大小为rows * cols的连续数组（例如，在类中使用std::vector<T>作为成员变量，并具有根据y * cols + x计算索引的函数。
