摘要： A method and system of identity masking to obscure identities corresponding to face regions in an image is disclosed. A face detector is applied to detect a set of possible face regions in the image. Then an identity masker is used to process the detected face regions by identity masking techniques in order to obscure identities corresponding to the regions. For example, a detected face region can be blurred as if it is in motion by a motion blur algorithm, such that the blurred region can not be recognized as the original identity. Or the detected face region can be replaced by a substitute facial image by a face replacement algorithm to obscure the corresponding identity.

摘要： The dataset describing an entity in a first modality and of a first, high resolution is used to enhance the resolution of a dataset describing the same entity in a second modality of a lower resolution. The two data sets of different modalities are spatially registered to each other. From this information, a joint histogram of the values in the two datasets is computed to provide a raw analysis of how the intensities in the first dataset correspond to intensities in the second dataset. This is converted into a joint probability of possible intensities for the missing pixels in the low resolution dataset as a function of the intensities of the corresponding pixels in the high-resolution dataset to provide a very rough estimate of the intensities of the missing pixels in the low resolution dataset. Then, an objective function is defined over the set of possible new values that gives preference to datasets consistent with (1) the joint probability distributions, (2) the existing values in the low resolution dataset, and (3) smoothness throughout the data set. Finally, an annealing or similar iterative method is used to minimize the objective function and find an optimal solution over the entire dataset.

摘要： Wiberg minimization operates on a system with two sets of variables described by a linear function and in which some data or observations are missing. The disclosure generalizes Wiberg minimization, solving for a function that is nonlinear in both sets of variables, U and V, iteratively. In one embodiment, defining a first function ƒ(U, V) that may be defined that may be nonlinear in both a first set of variables U and a second set of variables V. A first function ƒ(U, V) may be transformed into ƒ(U, V(U)). First assumed values of the first set of variables U may be assigned. The second set of variables V may be iteratively estimated based upon the transformed first function ƒ(U, V(U)) and the assumed values of the first set of variables U such that ƒ(U, V(U)) may be minimized with respect to V. New estimates of the first set of variables U may be iteratively computed.
