摘要:
Image-based localization technique embodiments are presented which provide a real-time approach for image-based video camera localization within large scenes that have been reconstructed offline using structure from motion or similar techniques. From monocular video, a precise 3D position and 3D orientation of the camera can be estimated on a frame by frame basis using only visual features.
摘要:
Methods for deriving and cultivating human embryonic stem (ES) cells and maintaining their pluripotency in culture is provided by utilizing secreted products obtained from the culture medium of human embryonic gem (EG) cell derivatives, such as embryoid body-derived cells. Substrates include compounds such as collagen I, fibronectin, or superfibronectin, or extracellular matrix, typically human derived.
摘要:
A system and method for reducing the likelihood of concurrency errors by identifying vulnerable segments of computer code and stalling other virtual machine threads of execution. According to one embodiment of the present invention, the vulnerable segment is identified at runtime, for example in a dynamic translator. According to another embodiment of the present invention, the vulnerable segment is identified ahead of time, for example in a static translator. According to yet another embodiment of the present invention, the vulnerable segment is identified in the binary translator of a virtual machine monitor.
摘要:
Compositions including topical formulations comprising secreted products obtained from the culture medium of human embryonic germ (EG) cell derivatives and particular combinations of components therefrom are provided for treatment of various dermatological conditions, such as adverse consequences of aging, wrinkling, altered pigmentation, altered viscoelasticity, and altered thickness, among others. Methods for using the compositions and topical formulations for treating adverse or undesirable dermatological conditions are also provided, as well as preventing the appearance of undesirable dermatological conditions.
摘要:
An article, such as a towel, having an opening to secure a twirling mechanism thereto. The twirling mechanism having a handle extending from a bottom portion thereof and having a mechanism to permit rotating of the handle with respect to the fabric-article, such that the fabric article is capable of twirling around the twirling mechanism. The twirling mechanism may in other embodiments include noise maker when the handle is rotated.
摘要:
A gigapixel image is generated from a set of images in raw format depicting different portions of a panoramic scene that has up to a full spherical field of view. Radiometric alignment of the images creates a set of images in radiance format. Geometric alignment of the radiance format images creates a set of true poses for the images in radiance format. A gigapixel image depicting the entire scene is assembled from the set of radiance format images and radiance format true poses for the images. The set of images in raw format is captured using a conventional digital camera, equipped with a telephoto lens, attached to a motorized head. The head is programmed to pan and tilt the camera in prescribed increments to individually capture the images at a plurality of exposures and with a prescribed overlap between images depicting adjacent portions of the scene.
摘要:
A system/method searches a traffic stream for a sequence of “matching” packets that exhibit a high degree of correlation or similarity to a sequence of “reference” packets. The correlation between matching and reference packets is based on a degree of correspondence between individual packets, as well as the sequence-order of the corresponding packets. A variation of the Needleman-Wunsch algorithm is preferably used to select corresponding packets in the traffic stream that provide a sequence-order that best matches the sequence-order of the reference packets, based on a measure of the correspondence for each match, and a penalty associated with each non-match. The algorithm is further modified to reduce the required search-space for finding corresponding packets in the traffic stream.
