Fast Kalman filtering 330 $aMany scientific, medical or engineering problems raise the issue of recovering some physical quantities from indirect measurements; for instance, detecting or quantifying flaws or cracks within a material from acoustic or electromagnetic measurements at its surface is an essential problem of non-destructive evaluation. The concept of inverse problems precisely originates from the idea of inverting the laws of physics to recover a quantity of interest from measurable data.Unfortunately, most inverse problems are ill-posed, which means that precise and stable solutions are not easy to devise 410 0$aDigital signal and image processing series. 606 $aInverse problems (Differential equations) 606 $aBayesian statistical decision theory 615 0$aInverse problems (Differential equations) 615 0$aBayesian statistical decision theory. 676 $a515/.357 676 $a519.542 701 $aIdier$b Je?ro?me$01593281 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910830737403321 996 $aBayesian approach to inverse problems$93913340 997 $aUNINA
