Systems, methods, and computer-readable media are provided for transferring color information from a no-flash image of a scene to a flash image of the scene using a localized tonal mapping algorithm. In some aspects, an example method can include obtaining a no-flash image and a flash image, mapping color information from the no-flash image to the flash image, and generating an output image including the flash image modified based on the mapping to include at least a portion of the color information from the no-flash image.

Systems and methods for color matching for realistic flash images

Techniques and systems are provided for segmenting one or more frames. For example, incremental optical flow maps can be determined between adjacent frames of a plurality of frames. Using the incremental optical flow maps, a cumulative optical flow map can be determined between a first frame of the plurality of frames and a last frame of the plurality of frames. A segmentation mask can be determined using the first frame of the plurality of frames. Foreground pixels of the segmentation mask for the last frame of the plurality of frames can then be adjusted relative to corresponding foreground pixels for the first frame. The foreground pixels can be adjusted using the cumulative optical flow map between the first frame and the last frame of the plurality of frames.

Motion assisted image segmentation

Techniques and systems are described herein for determining dynamic lighting for objects in images. Using such techniques and systems, a lighting condition of one or more captured images can be adjusted. Techniques and systems are also described herein for determining depth values for one or more objects in an image. In some cases, the depth values (and the lighting values) can be determined using only a single camera and a single image, in which case one or more depth sensors are not needed to produce the depth values.

Dynamic lighting for objects in images

Techniques and systems are provided for processing one or more low light images. For example, a short exposure image associated with one or more shutter speeds can be obtained. A long exposure image is also obtained, which is captured using a slower shutter speed than the one or more shutter speeds associated with the short exposure image. An output image can be generated by mapping color information from the long exposure image to the short exposure image.

Systems and methods for processing low light images

Exemplary methods, apparatuses, and systems for image processing are described. One or more reference images are selected based on image quality scores. At least a portion of each reference image is merged to create an output image. An output image with motion artifacts is compared to a target to correct the motion artifacts of the output image.

Reference image selection for motion ghost filtering

In general, techniques are described that facilitate processing of color image data using both a mono image data and a color image data. A device comprising a monochrome camera, a color camera and a processor may be configured to perform the techniques. The monochrome camera may be configured to capture monochrome image data of a scene. The color camera may be configured to capture color image data of the scene. The processor may be configured to perform intensity equalization with respect to a luma component of either the color image data or the monochrome image data to correct for differences in intensity between the color camera and the monochrome camera.

Performing intensity equalization with respect to mono and color images

In general, techniques are described that facilitate processing of color image data using both a mono image data and a color image data. A device comprising a monochrome camera, a color camera, and a processor may be configured to perform the techniques. The monochrome camera may capture monochrome image data of a scene. The color camera may capture color image data of the scene. A processor may determine a parallax value indicative of a level of parallax between the monochrome image data and the color image data and determine that the parallax is greater than the parallax threshold. The processor may further combine, in response to the determination that the parallax is greater than the parallax threshold, a luma component of the color image data with a luma component of the monochrome image data to generate a luma component of enhanced color image data.

Parallax mask fusion of color and mono images for macrophotography

A method for compositing images by an electronic device is described. The method includes obtaining a first composite image that is based on a first image from a first lens with a first focal length and a second image from a second lens with a different second focal length. The method also includes downsampling the first composite image to produce a downsampled first composite image. The method further includes downsampling the first image to produce a downsampled first image. The method additionally includes producing a reduced detail blended image based on the downsampled first composite image and the downsampled first image. The method also includes producing an upsampled image based on the reduced detail blended image and the downsampled first composite image. The method further includes adding detail from the first composite image to the upsampled image to produce a second composite image.

Systems and methods for compositing images

Local IP access is provided in a wireless network to facilitate access to one or more local services. In some implementations, different IP interfaces are used for accessing different services (e.g., local services and operator network services). A list that maps packet destinations to IP interfaces may be employed to determine which IP interface is to be used for sending a given packet. In some implementations an access point provides a proxy function (e.g., a proxy ARP function) for an access terminal. In some implementations an access point provides an agent function (e.g., a DHCP function) for an access terminal. NAT operations may be performed at an access point to enable the access terminal to access local services. In some aspects, an access point may determine whether to send a packet from an access terminal via a protocol tunnel based on the destination of the packet.

Local IP access scheme

Embodiments disclosed herein relate to carrier allocation and management in multi-carrier communication systems. In some embodiments, the number of carriers assigned to an access terminal on a forward link may be determined by an access network, and the number of carriers assigned to the access terminal on a reverse link may be based on a cooperative process between the access terminal and the access network. In other embodiments, the number of carriers assigned to the access terminal on the reverse link may also be determined by the access network, e.g., in relation to the scheduling information received from the access terminal.

Method and apparatus for carrier allocation and management in multi-carrier communication systems

Systems and methodologies are described herein that facilitate congestion control in a wireless communication system. As described herein, an access network and associated terminals can utilize a token bucket access control mechanism, through which respective terminals can be allotted access tokens and/or other units for access to the access network. For example, upon requesting access to a given network, a user of the network can determine whether sufficient access tokens have been accumulated, based on which the request can be selectively allowed or denied. As further described herein, multiple token bucket mechanisms can be utilized, which can correspond to respective packet flows or the like. Additionally, token bucket access control can be implemented as described herein in cooperation with conventional access persistence functionality. Further aspects described herein facilitate the adjustment of token bucket parameters for network access control based on network loading.

Embodiments disclosed herein relate to providing dynamic assignment of home agent and home address in wireless communications, such that a mobile node away from home may receive local access services from a visited network. In an embodiment, a mobile node accesses a visited network. The visited network authenticates the mobile node with its home network. The visited network then assigns a visited home agent and a home address for the mobile node. The mobile node subsequently performs secure binding with the visitor home agent. The mobile node proceeds with communications using the visitor home agent and home address.

Systems, devices, and methods are described for efficiently super resolving a portion of an image. One embodiment involves capturing, using a camera module of a device, at least one image of a scene, and creating a higher resolution image of a user-selected region of interest. The super resolution of the region of interest may be performed by matching a high resolution grid with a grid that is at the resolution of a device camera, populating the high resolution grid with information from an image from the camera, and then populating the remaining points of the grid that are not yet populated.

Systems and methods to super resolve a user-selected region of interest

A three-dimensional pose of the head of a subject is determined based on depth data captured in multiple images. The multiple images of the head are captured, e.g., by an RGBD camera. A rotation matrix and translation vector of the pose of the head relative to a reference pose is determined using the depth data. For example, arbitrary feature points on the head may be extracted in each of the multiple images and provided along with corresponding depth data to an Extended Kalman filter with states including a rotation matrix and a translation vector associated with the reference pose for the head and a current orientation and a current position. The three-dimensional pose of the head with respect to the reference pose is then determined based on the rotation matrix and the translation vector.
