Systems and methods for generating high dynamic images from interleaved Bayer array data with high spatial resolution and reduced sampling artifacts. Bayer array data are demosaiced into components of the YUV color space before deinterleaving. The Y component and the UV components can be derived from the Bayer array data through demosiac convolution processes. A respective convolution is performed between a convolution kernel and a set of adjacent pixels of the Bayer array that are in the same color channel. A convolution kernel is selected based the mosaic pattern of the Bayer array and the color channels of the set of adjacent pixels. The Y data and UV data are deinterleaved and interpolated into frames of short exposure and long exposures in the second color space. The short exposure and long exposure frames are then blended and converted back to a RGB frame representing a high dynamic range image.

A method for generating a digital image collage is provided. The method includes displaying a collage template on a user interface, wherein the collage template includes populating a plurality of randomly configured apertures with digital images; assigning a weight to each of the apertures based on an area of the apertures; and selecting a new digital image to add in the layout. In response to the user input command, comparing the weights assigned to the respective apertures in the layout to identify an aperture having the greatest weight among the apertures; randomly dividing the aperture having the greatest weight into two new apertures to change the layout to a different arrangement; and populating the two new apertures and the remaining undivided apertures among the plurality of apertures in the layout with the new selected digital image and the previously selected digital images, thereby generating the digital image collage.

Various methods and systems are provided for automatically registering and stitching images. In one example, a method includes entering a first image of a subject and a second image of the subject to a model trained to output a transformation matrix based on the first image and the second image, where the model is trained with a plurality of training data sets, each training data set including a pair of images, a mask indicating a region of interest (ROI), and associated ground truth, automatically stitching together the first image and the second image based on the transformation matrix to form a stitched image, and outputting the stitched image for display on a display device and/or storing the stitched image in memory.

Systems and methods for capturing omnistereo content for a mobile device may include receiving an indication to capture a plurality of images of a scene, capturing the plurality of images using a camera associated with a mobile device and displaying on a screen of the mobile device and during capture, a representation of the plurality of images and presenting a composite image that includes a target capture path and an indicator that provides alignment information corresponding to a source capture path associated with the mobile device during capture of the plurality of images. The system may detect that a portion of the source capture path does not match a target capture path. The system can provide an updated indicator in the screen that may include a prompt to a user of the mobile device to adjust the mobile device to align the source capture path with the target capture path.

An image processing device acquires first and second image data respectively representing first and second images. The first image includes an object image showing a part of an object. The second image shows another part of the object. The first image and the object image respectively include an edge and an object-image edge with respect to a direction. The first image includes first pixels that is located between the edge and the object-image edge and not included in the first object image. The device selects one of arrangement methods according to a condition that the number of first pixels continuously arranged in the direction is larger than a prescribed level. The device determines a relative position between the first and second images using the selected method. The device generates arranged image data representing an arranged image in which the first and second images are arranged according to the relative position.

Certain aspects of the technology disclosed herein include generating a virtual sound field based on data from an ambisonic recording device. The ambisonic device records sound of a surrounding environment using at least four microphones having a tetrahedral orientation. An omnidirectional microphone having an audio-isolated portion can be used to isolate sound from a particular direction. Sound received from the plurality of microphones can be used to generate a virtual sound field. The virtual sound field include a dataset indicating a pressure signal and a plurality of velocity vectors. The ambisonic recording device can include a wide angle camera and generate wide angle video corresponding to the virtual sound field.

A method and apparatus for Cone-Beam Computerized Tomography, (CBCT) is configured to increase the maximum Field-Of-View (FOV) through a composite scanning protocol and includes acquisition and reconstruction of multiple volumes related to partially overlapping different anatomic areas, and the subsequent stitching of those volumes, thereby obtaining, as a final result, a single final volume having dimensions larger than those otherwise provided by the geometry of the acquisition system.

Systems and methods are described where odometry information that is obtained from a video camera mounted on an underwater vehicle is used to estimate the velocity of the underwater vehicle. The techniques described herein estimate the velocity of the underwater vehicle passively without emitting sound or other energy from the underwater vehicle.
