Abstract: Techniques are described for passive three-dimensional (3D) face imaging based on macro-structure and micro-structure image sizing, such as for biometric facial recognition. A set of images of a user's face is processed to extract authentication deterministic macro-structure (DMAS) measurements. A database includes profile DMAS measurements, profile location definitions for deterministic micro-structure (DMIS) feature regions, and profile DMIS signatures computed for the DMIS feature regions. A first-level authentication determination can be based on comparing the authentication DMAS measurements with the profile DMAS measurements. Authentication DMIS signatures can be computed from sub-images obtained for the DMIS feature regions at the profile location definitions. A second-level authentication determination can be based on comparing the authentication DMIS signatures with the profile DMIS signatures.

Abstract: Improved under-display illumination is provided for display modules integrated in electronic devices. For example, a display module can include a number of display micro-structures, such as pixels and electrodes. Much of the illumination energy from conventional under-display illumination (e.g., for backlighting) can tend to be blocked by the micro-structures and can also tend to damage the micro-structures. Novel arrangements of optical structures are provided herein to output under-display illumination energy and to direct the energy in a manner that passes completely or mostly through gaps between the display micro-structures. Some implementations provide additional features, such as light conditioning to facilitate transmission of light energy through a dark coating layer, and/or use of multiple optical structures to provide illumination energy with different optical characteristics.

Abstract: Techniques are described for passive three-dimensional (3D) image sensing based on chromatic differentiation for use in object verification. For example, multiple sub-images correspond to 3D feature regions of an object. The sub-images can be analyzed to obtain respective sets of feature depth measurements (e.g., depth, textural signatures, etc.) based on multiple differentiated chromatic components of raw image sensor data captured from the object. A verification signal can be output as a function of comparing the respective sets of feature depth measurements from the plurality of characteristic sub-images to previously stored feature depth expectations, such that the verification signal indicates whether an identity of the object is verified and/or whether the object is a spoof.
