Join Mark Niemann-Ross for an in-depth discussion in this video Watching an animation of the process, part of Code Clinic: R (2015).
- What you're seeing right now is an animation…of what actually happens inside of…"Is This a Cropped Version of That".…The background image is actually haystack.Raster.…The image moving across the front is needle.Raster.…You're noticing how needle.Raster moves across…the face of haystack.Raster.…At each point that it stops, it's actually calculating…a cross-correlation function, and returning a value.…Again, we're looking for a maximum value…that approaches one, but at least is greater than .28.…
Mark introduces challenges and then provides an overview of his solutions in R. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
