Abstract: A method and system updates individualized calibrated tone-reproduction curves. A plurality of predetermined stored calibrated tone-reproduction curves are used, each predetermined stored calibrated tone-reproduction curve corresponding to a distinct media type and halftone type combination along with a plurality of predetermined relationships between each stored calibrated tone-reproduction curve and a reference media type and reference halftone type combination. A new tone-reproduction curve corresponding to a reference media type and reference halftone type combination calibration operation is generated, and each predetermined stored calibrated tone-reproduction curves based on the newly generated tone-reproduction curve corresponding to the reference media type and reference halftone type combination and the plurality of predetermined relationships between each stored calibrated tone-reproduction curve and the reference media type and reference halftone type combination is updated.

Abstract: This invention provides therapeutic compositions for the treatment or prevention of mental disturbances such as depressive states and for regulating the level of certain neurotransmitters and thereby improving the function of the central nervous system and cognitive function in humans and other animals. The therapeutic compositions comprise any two or more of tyrosine, one or more methylating agents, one or more phospholipids, one or more fatty acids and St. John's Wort (Hypericum perforatum), whether naturally, synthetically, or semi-synthetically derived. The invention also provides a method of administering these compositions to humans or animals in need thereof.

Abstract: This invention provides therapeutic compositions and combinations for the protection, treatment and repair of liver tissue. The invention relates to novel compositions and combinations comprising two or more compounds selected from the group consisting of S-adenosylmethionine, L-ergothioneine, and a substance selected from the group consisting of constituents of Milk thistle (Silybum marianum), silymarin and active components of silymarin, whether naturally, synthetically, or semi-synthetically derived, and to methods of preventing and treating liver disease and of repairing damaged liver tissue. The invention also provides a method of administering these compositions and combinations to humans or animals in need thereof.

Abstract: A method for segmenting a digital image into a foreground region and a key color region including characterizing a distribution of key color values; using the distribution of key color values to produce a multi-dimensional look-up-table having three or more dimensions indexed by color values in a selected color space to define a key color volume; addressing the multi-dimensional look-up table with color values of pixels in the digital image to determine whether the color values of such pixels are within the key color volume; and labeling pixels in the digital image whose color values fall within the key color volume to be within the key color region and labeling all other pixels to be within the foreground region whereby the digital image is segmented into the foreground region and the key color region.

Abstract: A method for determining a control signal for use in combining a first digital image that includes both a foreground region and a key color region having an associated key color with a second background digital image, both images including pixels having color values is disclosed. The method includes segmenting the first digital image into a foreground region and a key color region; and identifying transition region pixels in the first digital image that are in the vicinity of a boundary between the segmented foreground region and the segmented key color region. The method further includes computing a color difference signal between the color values of the first digital image and the key color for at least some pixels in the transition region; and computing a control signal for transition region pixels as a function of the color difference signal, where the control signal is to be used to combine the foreground region of the first digital image with the second background digital image.

Abstract: A method for combining a first digital image and a second background digital image, both images including pixels having color values, wherein the first digital image includes both a foreground region having foreground color values and a key color region characterized by a key color, as well as a mixed region where the pixel color values are a mixture of the foreground color value and the key color, includes determining a first control signal that indicates the relative proportions of the foreground color value and the key color for pixels in the first digital image; and segmenting the first digital image into a key color region and a non-key color region in which the non-key color region includes pixels in the first digital image that are not in the key color region.
