Gcamera measurement. the measurement from a camera can be expressed as y = ax + z, where x is the object position with mean µ and variance σ 2 x, a is the occlusion indicator function and is equal to 1 (if the camera can see the object) with probability p, and 0 (if the camera cannot see the object) with probability (1 − p), and z is the measurement error with mean 0 and variance σ 2 z . assume that x, a, and z are independent. find the best linear mse estimate of x given the camera measurement y . your answer should be in terms of only µ, σ 2 x, σ 2 z , and p.
