🛰️ Ce code sert à extraire les données et les métadonnées des ionogrammes numérisés des satellites Alouette et ISIS | 🛰️ This code is an effort to extract data and metadata from the scanned ionogram images from the Alouette and ISIS satellites.
The default _kerasocr text recognition model that was used could be further trained to better read NUM2 metadata numbers, and to only read numbers and not letters. For instance, there were at least 23,984 NUM2 images that seemed to adhere to the metadata format (i.e: had 15 characters beginning with ‘10’), but then had certain numbers misread as letters. There are also several instances where an image that is actually of NUM2 type was not read, perhaps due to scan quality issues. Further training of the text recognition model could improve the reading accuracy.
