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
