Figure 5: Results on a test sequence captured by the phone pilot system. (a)-(b) The detected feature points for panorama stitching, without feature selections. (c)-(d) The classified subregions with dense textures. For panorama, only a limited number of strongest features are selected from these regions. For image matching, we do not extract SURF features from
these regions. (e) The result of feature point registration. Note that very few or none of the corresponding features come from regions with dense textures, which are hard to match and also very expensive for geometric verification using RANSAC. (f )-(g) Stitching the images into a panorama. (g) Panorama image after blending, with recognized points of interest labelled.
