    Abstract: Apparatus, methods, systems, and instructions stored on computer-readable medium are presented for performing classification. A hardware engine may be configurable to implement multiple stages of a cascade classifier including a first stage and a second stage. The hardware engine may be configurable to (a) access a value indicative of whether to accumulate, and (b) responsive to the value indicative of whether to accumulate meeting a continue evaluation condition, (i) access a first numeric value obtained from evaluation of the first stage of the cascade classifier, (ii) accumulate the first numeric value with a second numeric value obtained from evaluation of the second stage of the cascade classifier to generate an accumulated value, and (iii) utilize the accumulated value to determine an outcome for the second stage of the cascade classifier.

    Abstract: Methods, systems, and devices for change detection are described. The methods, systems, and devices relate to monitoring a field of view of an image sensor via a first pixel associated with a group of pixels of the image sensor, where a dimension of the first pixel exceeds a dimension of at least one pixel of the group of pixels of the image sensor, detecting a change in the field of view of the image sensor based on the monitoring, and activating a second pixel of the image sensor based on detecting the change in the field of view of the image sensor.

    Abstract: Sensing of scene-based occurrences is disclosed. In one example, a vision sensor system comprises (1) dedicated computer vision (CV) computation hardware configured to receive sensor data from at least one sensor array and capable of computing CV features using readings from multiple neighboring sensor pixels and (2) a first processing unit communicatively coupled with the dedicated CV computation hardware. The vision sensor system is configured to, in response to processing of the one or more computed CV features indicating a presence of one or more irises in a scene captured by the at least one sensor array, generate data in support of iris-related operations to be performed by a second processing unit and send the generated data to the second processing unit.

    Abstract: Disclosed is a method and apparatus for generating a real-world traffic model. The apparatus obtains a first set of device map information associated with one or more devices that are in proximity with a first device, and obtains a second set of device map information associated with one or more devices that are in proximity with a second device. The apparatus determines whether the first set of device map information and the second set of device map information contain at least one common device and in response to the determination that the first set of device map information and the second set of device map information contain at least one common device, and generates a real-world traffic model of devices based on the first set of device map information and the second set of device map information.

    Abstract: Methods, systems, and devices for wireless communication are provided for mobility management for wireless communications systems that utilize a flexible bandwidth carrier. Some embodiments include approaches for determining bandwidth information, such as one or more bandwidth scaling factors N and/or flexible bandwidths, at a user equipment (UE), where the bandwidth information may not be signaled to the UE. Embodiments for determining bandwidth information include: random ordered bandwidth scaling factor approaches, delay ordered bandwidth scaling factor approaches, storing bandwidth scaling factor value in UE Neighbor Record approaches, spectrum measurement approaches, spectrum calculation approaches, and/or a priori approaches. Flexible bandwidth carrier systems may utilize spectrum portions that may not be big enough to fit a normal waveform. Flexible bandwidth carrier systems may be generated through dilating, or scaling down, time, frame lengths, bandwidth, or the chip rate of the flexible bandwidth carrier systems with respect to a normal bandwidth carrier system.
