Here are the options for Other Modalities Montage:
Layout Options
There are five choices of layouts: Similarity, Affine, Homography, Planar, and Cylindrical. Planar and Cylindrical are the same as for Photographic Montaging, Similarity is akin to Reposition, but somewhat more complicated. All five are explained in detail in .
Final Montage Crop Option
When i2k Retina forms the montage, the outlines of the images will form an irregular shape, especially when many images are being combined. Most users will want this montage cropped to a rectangular final image. i2k Retina will find the largest possible rectangle that fits inside the montage, and then decide whether or not to crop. This decision is controlled by the prior selection of buttons:
- The Auto button indicates that i2k Retina should crop the montage as long as enough of the image area is preserved within the rectangle. The percentage of area that must be preserved in order for cropping is controlled as a user preference.
- The Always Crop button tells i2k Retina to crop the montage no matter how much montage area is outside the largest possible rectangle.
- The Never Crop button tells i2k Retina to leave the montage uncropped.
Apply Masking
When this is selected, i2k Retina tries to find a convex border of pixels around the true image contents. This border region can be either bright or dark. The region is eliminated from consideration during the registration process.
Aggressive Registration
Clicking this button tells i2k Retina to be more aggressive than usual in trying to align each pair of images. This allows it to handle tougher cases while taking a bit more computation time. On rare occasions this leads i2k Retina to make mistakes, so this should be used only when ordinary registration fails and when the user is certain the images should be aligned.
