Estimation of stereo image pairs from single-camera views for a rotating spherical object covered with moving texture

In the field of astronomy, there is a need for a method to get three-dimensional information of 'corona' from an X-ray solar image. From the observation satellite 'Yohkoh', we can obtain images from different view angles by the rotation of the sun. However, in the case of changing textures on the sun's surface, stereo images lose the stereoscopic effect. To display accurate stereoscopic images, we propose a method for making a correct correspondence between stereo image pairs which includes varying surface using morphological processing and affine transformation.
