A method and system. An initial angle of rotation is determined by sampling test angles of rotation of a captured digital image and analyzing resultant rotated images to determine a resultant rotated image with a highest number of substantially empty lines. The captured digital image is rotated by the initial angle of rotation to generate a first rotated image. A representative line of each line area of multiple text line areas of the first rotated image is generated. A slope of each representative line is calculated. An aggregated slope of the representative lines is determined. The aggregated slope is converted to a refining angle of rotation. The refining angle of rotation is validated by finding points of intersection of lines connecting opposing ends of adjacent representative lines. The first rotated image is rotated by the refining angle of rotation to result in a final rotated image.

Automatic correction of skewing of digital images

A method and system for automatic correction of skewing of digital images. A captured digital image s provided. An initial angle of rotation is determined by sampling test angles of rotation of the input image and analyzing resultant rotated images to determine a resultant rotated image with a highest number of substantially empty lines. The input image is rotated by the initial angle of rotation to generate a first rotated image which is processed to determine a refining angle of rotation as follows: determining text line areas of the first rotated image; generating a representative line of each text line area; calculating a slope of each representative line; and determining an aggregated slope of all the representative lines. The aggregated slope is converted to the refining angle of rotation. The first rotated image is rotated by the refining angle of rotation to result in a final rotated image.

A system for virtualizing information technology (IT) appliances can include an IT appliance hosting facilities software. The IT appliance hosting facilities software can be implemented at a layer of abstraction above a virtual machine host, which is implemented in a layer of abstraction above a hardware layer of a computing system. The IT appliance hosting facilities software can include programmatic code functioning as virtualized hardware upon which a set of IT appliance software modules are able to concurrently run. The IT appliance hosting facilities software can provide caching, application level security, and a standardized framework for running the IT appliance software modules, which are configured in conformance with the standardized framework.
