摘要:
A video sequence having a plurality of frames is received. A feature in a first frame from the plurality of frames and a first position of the feature in the first frame are detected. The position of the feature in a second frame from the plurality of frames is estimated to determine a second position. A displacement vector between the first position and the second position is also computed. A plurality of content characteristics is determined for the first frame and the second frame. The displacement vector is spatially diffused with a spatial filter over a frame from the plurality of frames to generate a spatially diffused displacement vector field. The spatial filter utilizes the plurality of content characteristics. A temporal filter temporally diffuses over a video volume the spatially diffused displacement vector field to generate a spatiotemporal vector field. The temporal filter utilizes the plurality of content characteristics.

Systems, methods and articles of manufacture are disclosed for stereoscopically editing video content. In one embodiment, image pairs of a sequence may be stereoscopically modified by altering at least one image of the image pair. The at least one image may be altered using at least one mapping function. The at least one image may also be altered based on a saliency of the image pair. The at least one image may also be altered based on disparities between the image pair. Advantageously, stereoscopic properties of video content may be edited more conveniently and efficiently.

Techniques are disclosed for generating autostereoscopic video content. A multiscopic video frame is received that includes a first image and a second image. The first and second images are analyzed to determine a set of image characteristics. A mapping function is determined based on the set of image characteristics. At least a third image is generated based on the mapping function and added to the multiscopic video frame.

Systems and methods for generating a stereoscopic pair of images from a monoscopic image input are described. At least one brushstroke input corresponding to a location in the monoscopic image is received. A saliency map and edge map of the monoscopic image are computed. A first image warp and a second image warp are computed using the at least one brushstroke, the saliency map, and the edge map. A stereoscopic pair of images are generated from the first image warp and the second image warp.

A sling chair includes a back frame member having side rails held in substantially parallel relation by a pair of cross bar members. In one embodiment, the cross bar members are generally curved so as to extend away from the back faces of the side rails, forming a concave back structure which can receive a sling member and, eventually, a seated occupant. The cross bar members have a notch allowing for insertion of a flexible rod and sling loop and sling member after assembly of the cross bar members and side rails. Insertion of the flexible rod and sling loop does not require tools. The cross members are adapted to retain the sling member in secure fashion through upper and lower backrest assemblies, resulting in better support and more efficient assembly. This also facilitates separate provisioning of decorative features to improve the chair's aesthetic qualities.

Hollow decorative tubing fabricated from thin walled metallic stock material, the stock material preferably being stock tubing. Tubing is cold worked to impart any desired design such as simulated bamboo having realistic culm and node characteristics. The tubing is preferably formed into serial or repeating sections, each characterized by the desired design. For simulated bamboo, a realistic node is worked into the tubing between adjacent sections. The invention may be regarded as a method for manufacturing the resultant elongate hollow decorative tubing or, alternatively, an article of manufacture such as a chair incorporating the resultant elongate simulated bamboo article.
摘要:
A method and system for mounting wicker fibers onto furniture frame members; the system involves a flexible securing rod and at least one frame member with a channel configured to retain the securing rod. The frame member provides at least one channel access point along the channel that enables the securing rod to be inserted fully into the channel and further to enable a portion of the securing rod to be manipulated to expose a portion of the securing rod so that a wicker fiber can be looped around the securing rod. The exposed portion of the flexible securing rod may then be re-inserted into the channel. Thus, in application a frame member may be incorporated into a furniture frame in a complementary configuration permitting the wicker fibers to be woven. The wicker may be looped about securing rods located in complementary frame members so as to create a sling mounted wicker panel.
