The image processing module has the following responsibilities:
• | Check 'Folder to Process i.e. 'Acquisition Folder' and discover all FITS images within folder |
• | Sort images in reverse date order and start processing oldest image |
• | If required run image conversion i.e. convert image to png or jpg image and save to image conversion folder |
• | If required run line detection and save created detection images to detection folder. FTP detection images if required. |
• | If required copy original FITS image to Archive folder |
• | DELETE processed FITS image from 'Acquisition Folder' i.e. if settings do not tell the app to copy the FITS file to the archive folder the original FITS file is now gone! |
• | Create Video files during 'End of Session' tasks |

Image Processing Workflow
The purpose of running image conversions is to convert the created FITS files to either png or jpg files. This serves two purposes:
• | Reduce the required file size |
• | Allow the creation of movie files from the converted images |
Available Formats:
• | PNG: Lossless compression but bigger file size |
• | JPG: Lossy compression (adjustable in settings) but smaller file size |

Day Folder Creation
If set, the converted images can be put into individual folder according to the night they have been taken.

Line Detection
For full details on line detection features please see here.
As previously mentioned the 'Acquisition Folder' where original FITS files are created into is only a temporary storage place for these files i.e. when the image processing has finished these original FITS files will be deleted from that folder. To preserve original FITS files you can enable the 'Archive Original FITS Files' option in the settings.
For full details please see here.
It is possible to automatically create a video file at the end of each imaging night. This is run as part of the 'end of session tasks' which are run once the image acquisitions have stopped and all images have been processed from the acquisition folder. Please note that the video can only be created if the 'Image Conversion' process has created jpg or png images for the night. The video file will be created in the same folder as the converted images.
