An image processing apparatus for tracking faces in an image stream iteratively receives an acquired image from the image stream potentially including one or more face regions. The acquired image is sub-sampled at a specified resolution to provide a sub-sampled image. An integral image is then calculated for a least a portion of the sub-sampled image. Fixed size face detection is applied to at least a portion of the integral image to provide a set of candidate face regions. Responsive to the set of candidate face regions produced and any previously detected candidate face regions, the resolution is adjusted for sub-sampling a subsequent acquired image.

A modular scoring system using rank aggregation merges search results into an ordered list of results using many different features of documents. The ranking functions of the present system can easily be customized to the needs of a particular corpus or collection of users such as an intranet. Rank aggregation is independent of the underlying score distributions between the different factors, and can be applied to merge any set of ranking functions. Rank aggregation holds the advantage of combining the influence of many different heuristic factors in a robust way to produce high-quality results for queries. The modular scoring system combines factors such as indegree, page ranking, URL length, proximity to the root server of an intranet, etc, to form a single ordering on web pages that closely obeys the individual orderings, but also mediates between the collective wisdom of individual heuristics.

An image processing apparatus for tracking faces in an image stream iteratively receives a new acquired image from the image stream, the image potentially including one or more face regions. The acquired image is sub-sampled (112) at a specified resolution to provide a sub-sampled image. An integral image is then calculated for a least a portion of the sub-sampled image. Fixed size face detection (20) is applied to at least a portion of the integral image to provide a set of candidate face regions. Responsive to the set of candidate face regions produced and any previously detected candidate face regions, the resolution at which a next acquired image is sub-sampled is adjusted.

A multilingual multipoint videoconferencing system provides real-time translation of speech by conferees. Audio streams containing speech may be converted into text and inserted as subtitles into video streams. Speech may also be translated from one language to another, with the translated speech inserted into video streams as and choose the subtitles or replacing the original audio stream with speech in the other language generated by a text to speech engine. Different conferees may receive different translations of the same speech based on information provided by the conferees on desired languages.

A lens assembly is provided that has an index-of-refraction invariant structure. In one embodiment, a void between two lenses or lens elements in a lens assembly is filled with a desired gas, liquid or vacuum, the gas, liquid or vacuum having a pre-determined index of refraction. Once the void has been filled with the desired gas or liquid or been drawn down to a complete vacuum, the void is sealed by any of numerous appropriate means to render it leaktight. The lens assembly may then be tested or calibrated to ensure an appropriate level of optical performance prior to subsequent deployment under actual field conditions. Because the vacuum or filled void disposed in the lens assembly provides optical performance that is index-of-refraction invariant, the lens assembly may be employed successfully under widely varying atmospheric conditions and yet still provide the same high quality results.

In accordance with the invention, the textured surface to be rendered is sampled, or oversampled, at a variable rate that reflects variations in frequency among different regions, taking into account any transformation that will be applied to the surface prior to rendering and the view parameters of the display device, thus ensuring that each bin of the rendering process receives at least a predetermined minimum number of samples. A variety of image processing applications are contemplated wherein variable rate source sampling, and accumulation and resolution of forward mapped point samples can be applied, ranging from 3-D graphics applications to applications wherein images recorded in a recording / storage environment are mapped to the arbitrary requirements of a display environment.

Methods and apparatus for reducing or removing noise in digital images. Image noise reduction methods are described that may be applied to grayscale and color images, for example RGB images. An image noise reduction method may, before applying a noise filtering technique, transform the image values from linear space to flat noise space in which the noise is independent of the signal. An edge-preserving noise filtering technique may then be applied to the image in flat noise space. After noise filtering is applied, the image is transformed from flat noise space back to linear space. For color images, the flat noise space may be converted from linear color space to luminance-chrominance space before applying the noise filtering technique so that different filters can be applied to luminance and color channels. After applying the noise filtering technique, the image is converted back to linear color space.

Embodiments of the invention provide a system and method for distributed projects comprising computer systems and employing outsourced labor to be initiated, worked and completed.

Once the data is at the remote site both local and remote workers can divide and conquer the task at hand by further subdividing the project tasks that are worked on by each group of workers. Embodiments of the invention may transfer operations between sites instead of raw output data so that each site's work efforts can be added to the work product with minimal bandwidth. In at least one embodiment of the invention, the labor may be performed primarily by at least one site with at least one other site performing quality assurance primarily.

The HR data entry correlated to each identified matching LR data entry is then used to construct the output image by wrapping the correlated HR data entry onto the corresponding triangle on the triangularized input image.
