Abstract:
The invention provides a setting for a precious stone comprising a support for a precious stone; contact means for establishing a contact between the support and a stone within the support; a detector for detecting a break in the contact; and an emitter for emitting a signal on detection of the break in the contact. The setting provides a means of alerting wearers of an item of jewellery that the precious stone is loose within its support.
Abstract:
There is provided a method for assessing the integrity of grip of a stone in a jewellery setting having plural gripping claws to grip said stone, the method comprising heating the stone; measuring conductive transfer of heat from the stone to each of said plural gripping claws; and comparing said conductive heat transfer to said each gripping claw, wherein a marked difference in conductive heat transfer to any of the gripping claws indicates a lack of integrity of grip. Suitable apparatus is also provided.
Abstract:
A method and apparatus for compressing Z-stack microscopy images comprising compressing an all-focus image and depth map representation of an original Z-stack of images, computing a prediction residual as a difference between a simulated Z-stack, generated from the all-focus image and the depth-map, and the original Z-stack and concatenating the prediction residual to the compressed all-focus image and the depth map to produce a final compressed file.
Abstract:
A method or apparatus for stain separation comprising transforming a digital image from a first color domain to an optical domain to form an optical domain image (ODI), identifying a plane containing two or more basis vector which contain the pixels of the ODI, determining a plurality of orthogonal vector within the identified plane, forming a histogram of the digital image represented by the orthogonal vectors and determining one or more final stain vectors by searching for candidate vectors in the plane that minimize a cost function of the histogram.
Abstract:
A method for improving depth for field (DOF) in microscopic imaging, the method comprising combining a sequence of images captured from different focal distances to form an all-focus image, comprising computing a focus measure at every pixel, finding the largest peaks at each position in the focus measure as multiple candidate values and blending the multiple candidates values according to the focus measure to determine the all-focus image.
Abstract:
A method to estimate segmented motion uses phase correlation to identify local motion candidates and a region-growing algorithm to group small picture units into few distinct regions, each of which has its own motion according to optimal matching and grouping criteria. Phase correlation and region growing are combined which allows sharing of information. Using phase correlation to identify a small number of motion candidates allows the space of possible motions to be narrowed. The region growing uses efficient management of lists of matching criteria to avoid repetitively evaluating matching criteria.
Abstract:
A process and system for removing tars from synthesis gas uses glycerol produced as a byproduct of biodiesel manufacture. The biodiesel may be made from various oil feedstocks such as canola, rapeseed, or soybean oils. Associated with the harvesting of these crops may be the ready availability of byproduct biomass useful as feedstock for gasification. In addition, methanol may be sourced from the gasification of biomass to exploit a potential synergy between biodiesel manufacture and biomass gasification. The present invention develops those synergies further by making use of a byproduct stream from the manufacture of biodiesel to remove tars from the gasifier synthesis gas and to provide a useful end use for the byproduct.
Abstract:
Described are systems, methods, computer programs, and user interfaces for image location, acquisition, analysis, and data correlation that uses human-in-the-loop processing, Human Intelligence Tasks (HIT), and/or or automated image processing. Results obtained using image analysis are correlated to non-spatial information useful for commerce and trade. For example, images of regions of interest of the earth are used to count items (e.g., cars in a store parking lot to predict store revenues), detect events (e.g., unloading of a container ship, or evaluating the completion of a construction project), or quantify items (e.g., the water level in a reservoir, the area of a farming plot).

Methods of operating the system are also provided.
Abstract:
Apparatus and methods for generating a shutter-time compensated high spatial resolution (HR) image output by enhancing lower spatial resolution (LR) video images with information obtained from higher spatial resolution still images which are temporally decimated. Super-resolved images and LR SAD information is generated from the LR images and used for directing the extracting of information from the temporally decimated HR images to enhance the spatial resolution of the LR images in a blending process. By way of example blending can comprise: motion estimation, motion compensation of a temporally displaced HR still images and a super-resolved (SR) image input, transformation (e.g., DCT), generating motion error output, blending motion compensated images in response to LR motion error information; inverse-transformation into a shutter-time compensated HR video image output. Accordingly, a more cost effective solution is taught for obtaining a desired shutter time and video resolution.
