Abstract: An autonomous mobile device (AMD) in a physical space uses its own reflection to detect and map reflective surfaces. A first image is acquired by a camera of the AMD at a first time while a light on the AMD is turned on. The first image is processed to find a candidate reflection, characterized by a bright spot in the image. A second image is acquired at a second time while the light is off. The reflection is confirmed by absence of the candidate reflection in the second image. A display on the AMD presents a displayed image at a third time. A third image acquired during the third time is processed to find the features of the displayed image. Once found, a location and orientation in physical space of a plane of the surface causing the reflection is calculated. An occupancy map is updated to include this information.

Abstract: A layered video coding method is provided that selects data to upsamples from a base layer (BL) to provide to an enhancement (EL) to improved coding efficiency. The method determines a filter to determine an up-sampled value for a first layer for a video, wherein the filter has a set of coefficient values assigned to the filter. The up-sampled value is determined by applying the set of coefficient values to the plurality of sample values. The method then outputs the up-sampled value for use in coding a second enhancement layer (EL) of a higher resolution than the first layer. The up-sampled values may be for the 6/16 and ? 6/16 phase offsets.
