On this page we'll see how to unwrap a sequence of photographs containing 360 Degree Donut shots to convert them into cilyndrical panoramas.

The idea is to convert each sequence of images into panoramas in a single automatized step, using the same settings for all frames of a batch. For this we'll use . It is important to mention that this program is not free for everyone but only for those owners of a parabolic mirror, notwithstanding which the program is downloaded freely from the internet. The opened program looks like this :

We'll begin with the folder containing the first sequence of images, selecting them all and dragging the selection to the window of 0-360 UnWrapper :

After a few moments we can see the list of files loaded by the program for processing :

Using the mouse or the arrow keys on our keyboard or the combination of keys corresponding to our operating system, we´ll select the whole list so it is painted blue. We can choose to change the suffix with which the files created in this process will be distinguished from the rest, but for this example we will keep the default settings which will add to each file name the suffix _0360. We're ready to move on to the next screen by clicking on Next :

When the new tab is loaded we can see the automatic selection performed by the program over the first image of the list of files to be processed. As we selected all files in the previous step, the selection is applied equally to all images of the sequence :

While the automatic selection is pretty accurate, we prefer to adjust it manually to make sure the horizon line is a truly horizontal straight line in the panoramas we'll create. After some trials we are satisfied with the new nanual selection we have done. We can move on to the next step by clicking on Next :

In this step we can set the tones, saturation and black and white extreme points of the image. The default values ??calculated by the program are usually adequate, which is the case this time, so we will modify nothing and go on to the Next step :

In the contrast adjustment step we can make some small changes, as we have done, or go on straight to the Next step :

In this step we find several tabs with the available options for creating files. In the first tab called General we'll just choose the JPGE (Java Viewer) as we are neither interested in creating thumbnails nor Quick Time files or pages that contain these but only 360 degree panoramic images :

In the second tab we can perform adjustments to the quality of the files to be created :

Dragging the cursor to the end of the line will configure the program to optimize the created panoramas for best image quality. There is no need to check any of the available boxes since all of them are about file formats we are not going to deal with. For the same reason, none of the last two tabs at this step are of interest to us. We are ready to get the conversion started clicking on Next :

As the conversion process takes place we are shown a progress indicator :

When the conversion we can see a list of every panorama created together with a preview of the first one :

In the default location, ie, in the same folder that contains the original images now there are also the panoramas unwrapped from each one of those :

Going back to the open window of 0-360 UnWrapper we can once again click on Next to return to the first step of the sequence :

Clicking on Remove All we'll delete all files from the selected list :

We then have the list empty and ready to repeat the whole process, in this case with the folder containing the frames extracted from our second example video :

We start by dragging the new selection of files into 0-360 UnWrapper :

One after another, we repeat all the steps performed to the first folder until at the end of the process we have a panorama derived from each image in the source folder :

The panoramas are created like this :

Henceforth, working with the panoramas created in this step as frames we will edit the sequence for the interactive video we are going to create.
