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 to generate a first compressed digital image;determine a difference between at least a portion the uncompressed digital image and a corresponding portion of the first compressed digital image to generate difference image data;determine, based on the difference image data, a first amount of errors in the first compressed digital image;compare the first amount of errors to an error threshold included in the compression rule;in response to determining that the first amount of errors exceeds the error threshold, recompress, based on the compression rule, the uncompressed digital image to generate a second compressed digital image having a level of compression less than the first compressed digital image; anddetermine a second amount of errors based on comparison of the second compressed digital image to the uncompressed digital image.
