Abstract: Apparatuses, systems, media and/or methods may involve facilitating an image processing operation. User motion data may be identified when it user observes an image. A focus strength metric may be determined based on the user motion data. The focus strength metric may correspond to a focus area in the image. Also, a property of the focus strength metric may be adjusted. A peripheral area may be accounted for to determine the focus strength metric. A variation in a scan pattern may be accounted for to determine the focus strength metric. Moreover, a color may be imparted to the focus area and/or the peripheral area. In addition, a map may be formed based on the focus strength metric. The map may include a scan pattern map and a heat imp. The focus strength metric may be utilized to prioritize the focus area and/or the peripheral area in an image processing operation.

Abstract: Flood-fill techniques and architecture are disclosed. In accordance with one embodiment, the architecture comprises a hardware primitive with a software interface which collectively allow for both data-based and task-based parallelism in executing a flood-fill process. The hardware primitive is defined to do the flood-fill function and is scalable and may be implemented with a bitwise definition that can be tuned to meet power/performance targets, in some embodiments. In executing a flood-fill operation, and in accordance with an example embodiment, the software interface produces parallel threads and issues them to processing elements, such that each of the threads can run independently until done. Each processing element in turn accesses a flood-fill hardware primitive, each of which is configured to flood a seed inside an N×M image block. In some cases, processing element commands to the flood-fill hardware primitive(s) can be queued and acted upon pursuant to an arbitration scheme.

Abstract: Method, apparatus, and systems employing dictionary-based high-bandwidth lossless compression. A pair of dictionaries having entries that are synchronized and encoded to support compression and decompression operations are implemented via logic at a compressor and decompressor. The compressor/decompressor logic operatives in a cooperative manner, including implementing the same dictionary update schemes, resulting in the data in the respective dictionaries being synchronized. The dictionaries are also configured with replaceable entries, and replacement policies are implemented based on matching bytes of data within sets of data being transferred over the link. Various schemes are disclosed for entry replacement, as well as a delayed dictionary update technique. The techniques support line-speed compression and decompression using parallel operations resulting in substantially no latency overhead.

Abstract: Technologies for adjusting a perspective of a captured image for display on a mobile computing device include capturing a first image of a user by a first camera and a second image of a real-world environment by a second camera. The mobile computing device determines a position of an eye of the user relative to the mobile computing device based on the first captured image and a distance of an object in the real-world environment from the mobile computing device based on the second captured image. The mobile computing device generates a back projection of the real-world environment captured by the second camera to the display based on the determined distance of the object in the real-world environment relative to the mobile computing device, the determined position of the user's eye relative to the mobile computing device, and at least one device parameter of the mobile computing device.

Abstract: Techniques are disclosed for carrying our correlation search in contexts such as stereo algorithms of graphics systems. In accordance with an embodiment, the techniques employ a locality-sensitive hashing (LSH) function to reduce the number of bits to be processed during the correlation process, and to identify a sub-set of available image points that are likely to be the best match to a given target image point. Once such a sub-set of likely image points is identified, a more comprehensive correlation algorithm can be run, if so desired, to further ensure the quality of the match.
