摘要： Method and apparatus for automated staging of hair grafts using a camera for capturing one or more images of a staging area constructed for holding the hair grafts, and a controllable robotic arm having an aspiration tip mounted at a tool end thereof. An image captured by the camera is processed to identify a position of a hair graft in the image, and subsequent to distinguishing between a base end and a hair end of the hair graft in the image, an aspiration point is defined based at least in part on position of either or both of the base end and the hair end. The robotic arm is controlled to move the aspiration tip to the aspiration point, for aspiration of the hair graft into the aspiration tip. The aspirated graft may then be dispensed to a holding cartridge, sorted by number of hair grafts, or may be aspirated directly from the aspiration tip to a loading position in a hair implantation device, or to a loading position in a helper device for subsequent loading of the hair graft to a hair implantation device.

摘要： The present invention relates to a color management method for the conversion of internal color appearance space color values to CMYK device values, by interpolating CMY values from a plurality of CMY to color appearance space lookup tables, wherein each CMY table is associated with a specific value of K. A target internal color value is received and the relative purity of that color is calculated in the CMY space. Next, a black generation value is calculated using the relative purity of the target color. Finally, one of the plurality of CMY lookup tables is selected based on the black generation value, and a CMYK value is provided based on an interpolation from the selected lookup table. In this way, the present invention is able to control the output K value in a color appearance space to CMYK conversion. Accordingly, colors across a wide relative purity range, including natural images, can be reproduced with better accuracy and higher quality.

摘要： The present invention generates a color characterization model for performing transformation from a device-dependent color space of a color device to a device-independent color space. A first set of color measurement data is accessed corresponding to actual measurements of the color device, wherein the actual measurements define a measurement range in the device-dependent color space, and wherein the measurement data includes data point pairs, each data point pair having corresponding device-dependent values and device-independent values. Next, a second set of data point pairs is generated based on a predesignated set of device-dependent values outside the measurement range, by extrapolating device-independent values from the first set of color measurement data. The color characterization model is then determined based on both the first set of color measurement data and the generated second set of data point pairs. Because the color characterization model is determined based on actual measurements and extrapolated values, the color characterization model is wellbehaved and does not exhibit significant overshooting or undershooting beyond the measurement range.

摘要： The present invention provides a method for characterizing display devices. Initially, a plurality of colors are generated on the display device. The generated colors are measured and a black point and a white point are determined. The measured colors are then corrected for the determined black point in order to obtain a plurality of chromaticity values. The chromaticity values of the corrected color values are averaged, and a tristimulus matrix is generated with the averaged chromaticity values and the determined white point. By averaging the chromaticity values of black-point-corrected measurements, the present invention is able to create more accurate display device characterizations that account for the effects of flare. In addition, by averaging the chromaticity values of black-point-corrected measurements, the present invention minimizes the effects of inaccurate color measurements made during the device characterization process.

摘要： In response to a query to a database, the identity of a slave machine which stores the requested data is resolved, and the query is parsed to identify one or more shards at the slave machine. Each shard corresponds to a partition of the requested data stored at the slave, and rows inside of the shard are respectively assigned a fixed-size local ID. Tasks corresponding to each shard are placed into a thread pool, and the threads are processed using the respective local IDs to obtain the requested data.

摘要： A host computer is remotely controlled by a remote client device over a network that carries transmissions in a connection-oriented protocol and a connectionless protocol. The host computer establishes a connection to the remote client device using a connection-oriented protocol, and receives commands from the remote client device over the connection-oriented protocol and implements the commands so as to affect a display of the host computer. The host computer transmits content of the display to the remote client device using the connection-oriented protocol. In addition, the host computer identifies one or more rapid-change areas in the display of the host computer in which the display is changing more quickly than a predetermined threshold rate of change, and transmits content of each rapid-change area to the remote client device using a connectionless protocol at a rate higher than the connection-oriented protocol.

摘要： Generation of a transformed Interim Connection Space for spectral data is provided. A first Interim Connection Space for spectral data in a full spectral space is accessed. A first map, which characterizes a linear transformation from the full spectral space to a first color space, is accessed. A second map, which characterizes a linear transformation from the first Interim Connection Space to the first color space, is determined. The first Interim Connection Space is decomposed into orthogonal subspaces, the orthogonal subspaces including a first subspace that is a null space of the second map and a second subspace that is an orthogonal complement of the null space in the first Interim Connection Space. The transformed Interim Connection Space is generated based on the first subspace and the second subspace.

摘要： A color characterization process utilizing nonlinear regression analysis to characterize a color input device. The color input device is used to generate a bitmap of device dependent values from a color target. The bitmap of device dependent color values is used to generate a forward model that maps device dependent color values to color values in a device independent color space using a nonlinear regression analysis that minimizes a color difference metric between the reference color values and the set of device dependent color values mapped through the forward model. The color difference metric is chosen to represent human perceived color differences in the device independent color space. The performance of the nonlinear regression analysis may be improved by initializing the nonlinear regression analysis using an initial forward model generated from a linear regression analysis.
