title: Where can I find a good read about bicubic interpolation and Lanczos resampling?
body: <p>I want to implement the two above mentioned image resampling algorithms (bicubic and Lanczos) in C++. I know that there are dozens of existing implementations out there, but I still want to make my own. I want to make it partly because I want to understand how they work, and partly because I want to give them some capabilities not found in mainstream implementations (like configurable multi-CPU support and progress reporting).</p>
  
  <p>I tried reading Wikipedia, but the stuff is a bit too dry for me. Perhaps there are some nicer explanations of these algorithms? I couldn't find anything either on SO or Google.</p>
  
  <p><strong>Added:</strong> Seems like nobody can give me a good link about these topics. Can anyone at least try to explain them here?</p>
