Abstract: Systems and methods that enable implementation of content aware file management labeling. Techniques disclosed enable real-time analysis of a data file so that associations between the data file and applicable file management label(s) can be automatically suggested and/or made while a user is working in the data file. A user may deploy an application on a client device to edit a data file.

Abstract: This invention is related to a technical field of optical fingerprint recognition. It particularly designs a coordinate transformation method for imaging under screen, a storage medium and an electronic device. The a [sic] coordinate transformation method for imaging under screen includes steps of: calculating a coordinate system shrink coefficient; copying each luminous point in a fingerprint image to a shrunken coordinate system; and moving the entirety to the shrunken coordinate system with a relative distance between fingerprint information around a luminous point and a center of the luminous point being kept unchanged. Through coordinate transformation, restoration of the fingerprint image is guaranteed, and also pixels are guaranteed to not be lost at the same time, thereby ensuring the definition of the fingerprint image thus restored. In addition, this manner for restoring fingerprint images is simple in calculation process, fast in restoration speed, and good in quality.
