Creating a panoramic from video with Hugin

September 18, 2016 Patrick Gilfeather

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…

Photo Stitching with Hugin

Taking photos with my iPhone is fool proof, for the most part. The auto balance and focus take most of the effort out taking good shots. There is a lot that goes on behind the scenes that makes this possible. The image sensor data is queued and processed by the phone’s CPU with a bunch of commands in memory. In near realtime, the resulting information is sent to the screen so the operator can do what they need to do….

Multimedia Meta-data – More than meets the eye

It is time to step back from system administrative tasks and move back into the subject of digitized multimedia data processing. The subject is a vast ever evolving beast. Multimedia basically consists of some combination of visual or auditory information. With digitized multimedia, additional data can be layered which provides any number of uses. In this post, I’ll be focusing on image file meta-data. There are several levels and flavors of meta-data which I won’t cover in detail here. However,…
