DYNAMIC DIGITAL IMAGE COMPRESSION BASED ON DIGITAL IMAGE CHARACTERISTICS

摘要

Systems and techniques are disclosed for dynamically and automatically selecting an appropriate compression technique and/or compression parameters for digital images in order to reduce or prevent loss of significant information that may negatively impact the utility or usefulness of the digital images. For example, based on various image characteristics associated with a digital image, the system may dynamically compress the image using particular compression techniques and/or by adjusting compression parameters, to maintain significant information of the image. The system may select compression techniques and/or compression parameters based on one or more compression rules, which may be associated with image characteristics, patient characteristics, medical history, etc. Further, the system may, based on the one or more compression rules, compress the image to a maximum degree of compression while maintaining the significant information of the image.

1. A method of digital image compression, the method comprising:
causing execution of software instructions by one or more hardware computing devices in order to:
receive an uncompressed digital image;determine a characteristic associated with the uncompressed digital image;access a compression rule associated with the characteristic;compress, based on the compression rule, the uncompressed digital image using each of a plurality of compression levels to generate a set of compressed digital images that are each compressed at different compression levels;for each of the compressed digital images of the set, determine a respective amount of errors based on comparison of the respective compressed digital images to the uncompressed digital image; anddetermine a first compressed digital image of the set that:
is associated with an amount of errors that satisfies a threshold defined by the compression rule, andis compressed at a highest compression level of the plurality of compression levels that has an amount of errors that satisfies the threshold defined by the compression rule.
