20110305399 | IMAGE CLUSTERING - A database of images may be accessed. A feature set may be computed for each image, respectively. Each feature set includes feature integers quantized from interest points of a corresponding image. An initial set of clusters of the feature sets is found based on min hashes of the feature sets. Given the clusters of feature sets, descriptors for each of the clusters are computed, respectively, by selecting feature integers from among the feature sets in a cluster. The clusters are then refined by comparing at least some of the feature sets with at least some of the cluster descriptors, and based on such comparing adding some of the feature sets to clusters whose feature descriptors have similarity to the feature sets. | 12-15-2011 |

20080240551 | LOCAL BI-GRAM MODEL FOR OBJECT RECOGNITION - A local bi-gram model object recognition system and method for constructing a local bi-gram model and using the model to recognize objects in a query image. In a learning phase, the local bi-gram model is constructed that represents objects found in a set of training images. The local bi-gram model is a local spatial model that only models the relationship of neighboring features without any knowledge of their global context. Object recognition is performed by finding a set of matching primitives in the query image. A tree structure of matching primitives is generated and a search is performed to find a tree structure of matching primitives that obeys the local bi-gram model. The local bi-gram model can be found using unsupervised learning. The system and method also can be used to recognize objects unsupervised that are undergoing non-rigid transformations for both object instance recognition and category recognition. | 10-02-2008 |
20090316995 | BLUR ESTIMATION - A two-dimensional blur kernel is computed for a digital image by first estimating a sharp image from the digital image. The sharp image is derived from the digital image by sharpening at least portions of the digital image. The two-dimensional blur function is computed by minimizing an optimization algorithm that estimates the blur function. | 12-24-2009 |
20090324126 | IMAGE DECONVOLUTION USING COLOR PRIORS - Described are techniques for image deconvolution to deblur an image given a blur kernel. Localized color statistics derived from the image to be deblurred serve as a prior constraint during deconvolution. A pixel's color is formulated as a linear combination of the two most prevalent colors within a neighborhood of the pixel. This may be repeated for many or all pixels in an image. The linear combinations of the pixels serve as a two-color prior for deconvolving the blurred image. The two-color prior is responsive to the content of the image and it may decouple edge sharpness from edge strength. | 12-31-2009 |
20120321175 | LOCATION-AIDED RECOGNITION - A mobile device having the capability of performing real-time location recognition with assistance from a server is provided. The approximate geophysical location of the mobile device is uploaded to the server. Based on the mobile device's approximate geophysical location, the server responds by sending the mobile device a message comprising a classifier and a set of feature descriptors. This can occur before an image is captured for visual querying. The classifier and feature descriptors are computed during an offline training stage using techniques to minimize computation at query time. The classifier and feature descriptors are used to perform visual recognition in real-time by performing the classification on the mobile device itself. | 12-20-2012 |

20100147297 | Quick Connect Fitting for Respiratory Devices - There is provided a novel fitting having male and female ends and a tapered internal luer-type seal. The male fitting end has a periphery upon which is mounted at least one boss. The female fitting end has a slot into which the boss may be inserted. At the bottom of the slot is a stop to limit the insertion depth of the boss. The male and female ends may then be rotated relative to each other to move the boss into a window on the female end. The window has a frame and the upper frame is angled slightly, corresponding to the boss, which serves to draw the male end farther in to the female end. The window has a side frame that stops the rotational movement of the boss. When the movement of the boss is stopped, the male and female tapers are in substantially leak-free contact. There is also provided a closed suction catheter using the novel fitting, such that the catheter may be easily and quickly removed and replaced. | 06-17-2010 |
20100147310 | Respiratory Access Port Assembly With Push Button Lock and Method of Use - A respiratory access assembly includes a distal plate having one port and cuff and an axially aligned proximal plate including a first port and first cuff and a second port and second cuff. The distal plate is configured to move relative to the proximal plate. The respiratory access assembly includes an actuator, which has a plurality of predetermined positions. When the actuator is positioned in a movement-enabling position, it permits movement of the plates while simultaneously blocking the first port of the proximal plate. When the actuator is positioned in a first locked (open) position, it locks the plates together and aligns the port of the distal plate with the first port of the proximal plate and un-blocks the first port of the proximal plate so that an object, such as a suction catheter, may be positioned through the aligned ports. When the actuator is positioned in a second locked (open) position, it locks the plates together and aligns the port of the distal plate with the second port of the proximal plate and un-blocks the first port of the proximal plate so that an object may be positioned through the aligned ports. When the actuator is positioned in the third locked (closed) position, it locks the plates together such that the port of the distal plate is positioned between the first port and the second port or the proximal plate and all ports are out of alignment with each other, such that all ports are blocked by a portion of one plate so that no object is moveable through any of the ports. A method of using a respiratory access assembly is provided. | 06-17-2010 |
20120152256 | Respiratory Access Port Assembly with Push Button Lock and Method of Use - A respiratory access assembly includes a distal plate having one port and cuff and an axially aligned proximal plate including a first port and first cuff and a second port and second cuff. The distal plate is configured to move relative to the proximal plate. The respiratory access assembly includes an actuator, which has a plurality of predetermined positions. The actuator can lock the plates together such that the distal port is aligned with either port of the proximal plate or so that the distal port is not aligned with either port of the proximal plate. A method of using a respiratory access assembly is provided. | 06-21-2012 |
