Abstract: A system for adding persistence to SPAD imagery is configurable to capture, using a SPAD array, a plurality of image frames. The system is configurable to capture, using an IMU, pose data associated with the plurality of image frames. The pose data includes at least respective pose data associated with each of the plurality of image frames. The system is configurable to determine a persistence term based on the pose data. The system is also configurable to generate a composite image based on the plurality of image frames, the respective pose data associated with each of the plurality of image frames, and the persistence term. The persistence term defines a contribution of each of the plurality of image frames to the composite image.

Abstract: Devices, systems, methods, and computer program products for performing medical procedures are disclosed herein. In some embodiments, a system for performing a medical procedure includes a medical instrument configured to be inserted within an anatomic region and including an image capture device. The system can receive a three-dimensional (3D) model of the anatomic region, the 3D model including a model landmark corresponding to an anatomic landmark in the anatomic region. The system can obtain, via the image capture device, a plurality of images of the anatomic landmark, at least some of the images representing different views of the anatomic landmark. Based on the images, the system can determine a set of transformation parameters for aligning the anatomic landmark with the model landmark. The system can use the set of transformation parameters as a seed for registering the 3D model to the anatomic region.

Abstract: Disclosed is an illuminant estimation method for an electronic device. The method comprises: acquiring two frames of images, the distance between which is greater than a set distance; detecting shadows of the two frames of images, extracting pixel feature points of the shadows, determining point cloud information of the shadows, and distinguishing point clouds of the different shadows according to the point cloud information of the shadows; acquiring point cloud information of the multiple objects, and distinguishing point clouds of the different objects according to the point cloud information of the multiple objects; matching the point clouds of the different shadows and the point clouds of the different objects to determine shadows corresponding to the different objects; and determining the position of the illuminant according to a positional relation between the objects and the corresponding shadows.

Abstract: Examples are disclosed that relate to blending different types of images captured by different types of cameras employing different sensing modalities based on a dynamic weighting. The dynamic weighting is calculated based on a dynamic quality proxy that serves as an approximation of image quality that may change from image to image. In one example, a first image of a scene is received from a first camera. A dynamic quality proxy is received. A second image of the scene is received from a second camera with a different sensing modality than the first camera. A composite image blended from the first and second images in proportion to a dynamic weighting that is based on the dynamic quality proxy is output.
