Abstract: A method, apparatus and computer program product are provided to identify one or more salient events from an analysis of one or more images in an efficient and accurate manner. In this regard, the method, apparatus and computer program product may limit the visual analysis of the images to only a subset of the images that are determined to be potentially relevant based upon sensor information provided by one or more sensors carried by the image capturing device. In the context of a method, one or more images that are captured by an image capturing device are identified to be a salient video segment based upon sensor information provided by one or more sensors carried by the image capturing device. The method also includes identifying one or more salient events based upon an analysis of the one or more images of the salient video segment.

Abstract: An apparatus includes circuitry configured to: partition an input tensor into one or more block tensors; partition at least one of the block tensors into one or more continuation bands, the one or more continuation bands being associated with a caching counter having a value; store the one or more continuation bands in a cache managed using a cache manager; retrieve, prior to a convolution or pooling operation on a current block tensor, the one or more continuation bands of a previous block tensor from the cache that are adjacent to a current block tensor; concatenate the retrieved continuation bands with the current block tensor; apply the convolution or pooling operation on the current block tensor after the concatenation; decrease the respective caching counter value of the retrieved continuation bands; and clear the continuation bands from the cache when its respective caching counter reaches a value of zero.

Abstract: A method, an apparatus and a computer program are provided. The method comprises defining a first mapping that maps a virtual space to a real space; using a tracked real point of view of a user in the real space and the first mapping to determining a virtual point of view of the user within the virtual space defined by the user's virtual location and virtual orientation; causing rendering to the user of at least part of a virtual scene determined by the virtual point of view of the user within the virtual space, while the virtual space is mapped to the real space using the first mapping; altering, based on a grasp and move gesture performed by the user on a virtual location in the virtual space that differs from the virtual location partially defining the user's virtual point of view, the mapping of the virtual space to the real space from the first mapping to a second mapping; using a tracked real point of view of the user in the real space and the second mapping to determine a virtual point of view of the user within the virtual space defined by the user's virtual location and virtual orientation; and causing rendering to the user of at least part of a virtual scene determined by the virtual point of view of the user within the virtual space, while the virtual space is mapped to the real space using the second mapping.
