# using Kalman Filter

Hi folks,

I write a project to track points with Kalman Filter. There are 4 points, each with x,y coordinates. So, in my case, it's neater if I use a 2x4 Mat as state or measurement matrices.

OpenCV Kalman FIlter works well with 1D Mats as matrices. But in my case, it crashes.

Is this because OpenCV Kalman Filter doesn't work with 2D matrices??

OpenCV documentation does not tell clearly about this. Anyone has tried, plz give me a hint
