Example 1. Given a set of scattered data which were sampled from an image
with sample rate =50%. We first use the sample data to recover the image
based on exact image pixel values. For simplicity, we use an image penny
from MATLAB. Our demo matlab program can be found at
DEMOpenny.m To run this code, you also need
SMOOTH.m
In the following, we first show
the sampled image and then recovered image.
