It is safe to assume that computers will continue to be used to advance this field of understanding. Here you will be introduced to this technology. Together, we will cover the history of radiographic imaging and how it has arrived to were it is today. I will also cover one of the techniques used in computerized tomography…

Creating a panoramic from video with Hugin

Creating a panoramic from video with Hugin

Hugin is a great tool for stitching photos together that share common features to create a higher resolution image. In the previous post, we covered stitching two photos together. In this post we’ll cover using video as a source for our stitching base, as well as the requirements. The Hugin program uses EXIF data in its stitching process. Lets start by creating a 360 panorama using a series of photos taken with an iPhone. The images inherently contain EXIF data…
