7.3.1 Resizing Images

Too much Y parallax occurs in the S2/S3 and S1/S7 pairings of the raw Ottawa imagery. In these combinations, Y parallax is the result of differences in scale. The differences in scale between each image pair are 12.8 and 15.7 per cent respectively. As a general rule, scale differences greater than 10 percent in RADARSAT imagery will produce too great a Y parallax. The S1, S2 and S3 images have been re-scaled to the image dimensions of the S7 image. Once resized, any combination of these images can be successfully viewed in stereo.
