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.
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:
Systems and methods may provide for receiving a short range signal from a sensor that is collocated with a short range display and using the short range signal to detect a user interaction. Additionally, a display response may be controlled with respect to a long range display based on the user interaction. in one example, the user interaction includes one or more of an eye gaze, a hand gesture, a face gesture, a head position or a voice command, that indicates one or more of a switch between the short range display and the long range display, a drag and drop operation, a highlight operation, a click operation or a typing operation.
Abstract:
Method, apparatus, and systems employing novel delayed dictionary update schemes for 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:
Techniques to determine a search range for a stereo based matching pyramid. A first disparity estimation value for a first level in a stereo based matching pyramid based on an image may be received. A search range for a second level may be determined using the first disparity estimation value. The search range based on a pyramid level of a second level may be increased. The search range may be increased based on a pyramid level of the second level. A second disparity estimation value may be selected from the search area for the second level. A depth map for the second level may be determined based on the second disparity estimation value. Other embodiments are described and claimed.

Abstract:
Techniques to provide efficient stereo block matching may include receiving an object from a scene. Pixels in the scene may be identified based on the object. Stereo block matching may be performed for only the identified pixels in order to generate a depth map. Other embodiments are described and claimed.
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.
