During the transformation by fusion, the processing of fusion may be done on each pixel by using a pixel weight graph, so that the image of the object in the original picture may be better integrated into the template picture with the features of the object in the original picture maintained well in the picture processed by fusion.
US11205250B2 Updating a fixed pattern noise matrix
A method for updating a fixed pattern noise matrix comprises: calculating a first difference between a target and first different images in a video stream to obtain a first differential matrix; calculating a second difference between the target and second different images in the video stream to obtain a second differential matrix; identifying a set of candidate positions for fixed pattern noise by: locating first and second sets of positions in the first differential matrix at which a difference deviates from predetermined values, finding a set of overlapping positions between the first and second sets of positions, and adjusting the set of overlapping positions. The adjusted set of overlapping positions is used for fixed pattern noise. Furthermore, each position in the set of candidate positions is updated, wherein the updated fixed pattern noise value at each position is based on a value at a corresponding non-adjusted position in the differential matrix.

US11205238B1 Private digitized, decentralized and distributed controlled-environment facility ledger systems and methods
A private digitized, decentralized, and distributed controlled-environment facility ledger is created using a genesis hash and wallet code assigned to a controlled-environment facility resident upon intake of the resident into the facility. In response to an occurrence of a first controlled-environment facility transaction with respect to the resident, a first new hash containing a cryptographic hash of the genesis hash is built, and the ledger is updated to reflect the first transaction, and to associate the first new hash with the first transaction, both with respect to the resident. Thereafter, subsequent new hashes, each containing a cryptographic hash from each prior hash, are each built in response to each subsequent controlled-environment facility transaction with respect to the resident, and the ledger is updated to reflect each subsequent transaction, and associate each subsequent new hash with the respective subsequent transaction, both with respect to the resident.
