Photo Stacking is again renamed...
I can't make up my mind on the app name...doh. The new app name is: Foto stackR
Also updated is the image alignment options: you will now find a slider to control the image sampling grid for feature matching when choose ORB as the alignment method.
The default image transform for ORB is also change to "rigid transform". By default the app tries to: translate/rotate/scale the image when performing alignment. You can enable additional shear/perspective/ transform with the toggle switch: test perspective transform.
No change in ECC alignment method.
I have also put together a simple web page that explains the alignment settings/parameters:
The link to the above webpage is also available from within the app
