Thank you in advance. I am not sure if B-spline/NURBS can express as basic function in matrix, as, $$ x(t)=B(t)c $$ $$ B(t)=[b_1(t)...b_M(t)] $$ in which x(t) is a Dx1 states, B(t) is known temporal ...
I am trying to do a natural cubic spline but I'm having trouble. f(-.0247500)=-.5, f(.3349375)=-.25, f(1.101000)=0 I tried doing the matrix, Ax=b where, h0=h1=.25 an a0=-.0247500, a1=.3349375, ...
I am trying to keep the outline of an object in a video. So I have the coordinate of the outline of the object in the image $t$ and after computing the optical flow I have the coordinate in the image ...
