Superresolution Testing and Results

Module by: Jennifer Gillenwater, J. Ryan Stinnett, Elica Skorcheva

Summary: Using projective flow and Delauany triangulation to accompish image registration and interpolation, we achieved the following superresolution results.

The following images illustrate the effects of the projective flow and Delaunay triangulation algorithms we used to implement image superresolution. Our testing process was as follows:

Take several pictures of the same object with a digital camera (no tripod -> images will need registration).
Downsample the images to create low-resolution (LR) copies.
Register all LR images with respect to the first LR image.
Interpolate to obtain the HR image.

We also tested using LR images from external sources. An example is given below.

Original images:
Figure 1: LR image 1 (Source: 7)

Figure 2: LR image 2 (Source: 7)

Figure 3: LR image 3 (Source: 7)

Figure 4: LR image 4 (Source: 7)
