Patent number: 11222443Abstract: A system and method to compress image data by first identifying the device and settings with which the image data was generated, and then optimizing the compression accordingly. A catalogue that associates imaging devices and settings to compression parameters is generated, so that when an image needs to be compressed, the system will identify the device and settings and extract compression parameters from the catalogue. These parameters are used during compression to achieve higher compression performance and optionally to normalize the compressed data as to make it more homogenous for further processing.Type: GrantFiled: March 26, 2020Date of Patent: January 11, 2022Assignee: Dotphoton AGInventors: Christoph Clausen, Bruno Sanguinetti
