GPU-Efficient Recursive Filtering and Summed-Area Tables: Transcript

D Nehab 1 A Maximo 1 R S Lima 2 H Hoppe 3 1 IMPA 2 Digitok 3 Microsoft Research Linear shiftinvariant filters But use feedback from earlier outputs. The recursive average is a very efficient way to obtain a time-weighted average by low-pass filtering the signal.. y[n] = (1-a)y[n-1] + ax[n]. Consider the output for a step input if a = 0.632. Output initialized to 0. F01943024. Reference. Yang, . Qingxiong. . "Recursive bilateral filtering." . ECCV . 2012. .. Deriche. , . Rachid. .
