    Hi

    I have an issue using ICE for a particular panorama - the images were shot either with a full frame camera and a 12 mm rectlilinear lens (Sigma EX 12-24 mkI) or a 1.6x cropper and an 11 mm lens. In both cases the lens were pointed around 45° upwards to include the top of the building and images were shot to cover 360° around. I tried to stitch these images both in both ICE 1.4.4.0 (which I prefer) and 2.0.3 (both 64 bit versions), but in both cases the ICE limits the vertical AOV to 89.7° of the stitch so that the top of the building is cropped of. If using the "Horizontal Sphere" projection ICE utilizes 97° vAOV, but I want to use the "horizontal cylinder" projection

    I do not suppose this can be corrected in a revision of the 1.x version of the software, but perhaps 2.x then :-)

    Below a screenshot of ICE stitching the images

    And below a reduced version of the image including the tower, that get cropped at the top

    Hi

    While waiting for a fix, I have experimented a little with ICE to see what causes the problem. As can be seen at the screenshots below where I just utilize 3 of the images, ICE starts to crop the top as the horizontal cylinder projection is rotated to make the vertical lines "vertical" - as a result the hAOV goes from 94° to 89°

    Hi

    I am still hoping for a comment from Microsoft - is there a way to prevent this cropping, or will the issue be dealt with in upcoming versions?

    Meanwhile I made a function in my own software (RectFish) to stretch the ICE 2.0.3 Mercator panorama into a square image.

    Unfortunately Matt Uyttendaele and Eric Stollnitz who used to work on ICE at Microsoft Research have moved on to Facebook Research and Adobe Research respectively around November of 2015, so I doubt that Microsoft will be giving you the feedback you'd hoped for or (for that matter) adjusting how ICE works in response to your feedback. I hate to be the bearer of bad tidings (and if there's still someone at Microsoft who is working on ICE, please let me know so I stop posting messages like the above) but I thought you deserved to know what little I know about the situation.
