Abstract:
A mobile electronic device processes a sequence of images to identify and re-identify an object of interest in the sequence. An image sensor of the device, receives a sequence of images. The device detects an object in a first image as well as positional parameters of the device that correspond to the object in the first image. The device determines a range of positional parameters within which the object may appear in a field of view of the device. When the device detects that the object of interest exited the field of view it subsequently uses motion sensor data to determine that the object of interest has likely re-entered the field of view, it will analyze the current frame to confirm that the object of interest has re-entered the field of view.

A method, non-transitory computer-readable medium, and apparatus for localizing a region of interest using a dynamic hand gesture are disclosed. For example, the method captures the ego-centric video containing the dynamic hand gesture, analyzes a frame of the ego-centric video to detect pixels that correspond to a fingertip using a hand segmentation algorithm, analyzes temporally one or more frames of the ego-centric video to compute a path of the fingertip in the dynamic hand gesture, localizes the region of interest based on the path of the fingertip in the dynamic hand gesture and performs an action based on an object in the region of interest.

A system and method for monitoring parking and identifying vehicles by monitoring a parking region based on video data of the parking region received from a video camera, detecting a parking event associated with a vehicle in the parking region, adjusting a view of the video camera based on the parking event, physically tracking the vehicle using the video camera, capturing an image of a license plate of the vehicle, and resuming monitoring the parking region after capturing the image of the license plate.
Abstract:
A method, non-transitory computer readable medium, and apparatus for localizing a region of interest using a hand gesture are disclosed. For example, the method acquires an image containing the hand gesture from the ego-centric video, detects pixels that correspond to one or more hands in the image using a hand segmentation algorithm, identifies a hand enclosure in the pixels that are detected within the image, localizes a region of interest based on the hand enclosure and performs an action based on the object in the region of interest.
Abstract:
A method for removing false foreground image content in a foreground detection process performed on a video sequence includes, for each current frame, comparing a feature value of each current pixel against a feature value of a corresponding pixel in a background model. The each current pixel is classified as belonging to one of a candidate foreground image and a background based on the comparing. A first classification image representing the candidate foreground image is generated using the current pixels classified as belonging to the candidate foreground image. The each pixel in the first classification image is classified as belonging to one of a foreground image and a false foreground image using a previously trained classifier. A modified classification image is generated for representing the foreground image using the pixels classified as belonging to the foreground image while the pixels classified as belonging to the false foreground image are removed.
Abstract:
A system is provided comprising: a light field emanating from a scene and a positive imaging lens focusing light from the light field onto a DMD array. A first collector lens directs the spatially modulated light to a first photodetector having a spectral sensitivity to a first spectral band. The first photodetector senses the directed light from the first pixel-wise multiplication and produces a signal representing a first inner product between the light incident on the DMD and the first basis function for the first spectral band. A second collector lens directs the spatially modulated light to a second photodetector having a spectral sensitivity to a second spectral band. The second photodetector senses the directed light from the first pixel-wise multiplication and produces a signal representing a first inner product between the light incident on the DMD and the first basis function for the second spectral band.
Abstract:
Disclosed herein is a single-pixel camera system and method for performing spot/area measurement of a localized area of interest identified in a scene and for performing spatial scene reconstruction. A switching module enables a single-pixel camera to alternate between a spot/area measurement mode and a spatial scene reconstruction mode. In the case where the operative mode is switched to spot measurement, a light modulation device is configured to modulate incoming light according to a clustered pattern that is specific to a localized area of interest intended to be measured by integrating across the pixels to generate an integral value. In the case where the operative mode is switched to spatial scene reconstruction, the light modulation device can be configured to modulate incoming light to display a spatial pattern corresponding to a set of predetermined basis functions.
Abstract:
A method, non-transitory computer readable medium, and apparatus for managing inventory are disclosed. For example, the method monitors a region of interest to determine an inventory level based upon a depth image captured by a depth sensing device, calculates a change in a depth in the region of interest from the depth image that is captured and determines a change in the inventory level associated with the change in the depth of the region of interest.
