Abstract: Embodiments are directed to perceiving scene features using event sensors and image sensors. Paths may be scanned across objects in a scene with one or more beams. Images of the scene may be captured with frame cameras. Events may be generated based on detection of beam reflections that correspond to the objects. Trajectories may be based on the paths and the events. A distribution of intensity associated with the trajectories may be determined based on the energy associated with the traces in the images. Centroids for the trajectories may be determined based on the distribution of the intensity of energy, a resolution of the frame cameras, or timestamps associated with the events. Enhanced trajectories may be generated based on the centroids such that the enhanced trajectories may be provided to a modeling engine that executes actions based on the enhanced trajectories and the objects.

Abstract: An imaging system is configured with an autofocus operation that refocuses multiple cameras of the imaging system on detected features of interest, instead of on the whole image of the sample. Focus measures are calculated on the detected features, and then aggregated to focus distances of actuator moving the camera array, the sample stage, or individual cameras based on a maximization of detected features to be in focus. After the refocus, the imaging system recaptures new images and analyzes features on the new images to generate statistical characterization of the sample based on the classification of the features.

Abstract: A method includes transcoding a first block from a spatial region. The first block is associated with a first block tree pattern defining a structure of splitting a block into smaller blocks. A bit string of bits for the first block tree pattern is included in an encoded bitstream. The method determines a location of the first block in the spatial region when the first block tree pattern of the first block can be reused for a second block tree pattern of a second block. The spatial region includes blocks and the location is based on the first block being in the spatial region. Information for the second block is included in the encoded bitstream that indicates the location of the first block in the spatial region. The location allows the bit string for the first block tree pattern to be retrieved for use to decode the second block.
