    • A digital image processing method for generating a low resolution, low bit depth digital image from a higher resolution, higher bit depth input color digital image, includes the steps of: generating a gray scale image from the input color digital image; generating a valley image; filtering the valley image with a rank order filter to produce a filtered valley image; thresholding the filtered valley image to generate a binary valley image; generating a shadow image and a highlight image from the gray scale image; combining the shadow image, the highlight image, and the binary valley image to produce a combined binary image; and sub-sampling the combined binary image to a desired low resolution.

    • A photographic element, is disclosed which includes a support and at least three silver halide emulsion layers, that records exposure information. The exposure information is recorded in three image-recording units and wherein the spectral sensitivities of said image-recording units are chosen such that the average color error, .DELTA.E*.sub.ab, is less than or equal to 3.1. .DELTA.E*.sub.ab is computed for a specified set of test colors of known spectral reflectance, and the light source is specified as D.sub.65. .DELTA.E*.sub.ab is the average CIE 1976 (L*a*b*) .DELTA.E*.sub.ab between the CIE 1976 (L*a*b*)-space coordinates of said test colors and the CIE 1976 (L*a*b*)-space coordinates corresponding to transformed exposure signals. The transformed exposure signals are formed by applying an exposure-space matrix to the exposure signals derived from the photographic element to transform the derived exposure signals to exposure signals corresponding to the color-matching functions of the CCIR Recommendation 709 primary set. The exposure-space matrix is derived so as to minimize ##EQU1## and noise-gain factor, .PSI., defined as the sum of the square roots of the sum of the squares of each row of the elements in the exposure space matrix is less than or equal to 6.5.

    • A method for segmenting a first object from a bounding object within a digital image identifies pixels between first and second endpoint pixels. A volume of interest is defined spanning at least a portion of the object. Pixels within the volume of interest are partitioned into a first subset of pixels that are neither the first object nor bounding object pixels and second subset of pixels that are not contained in the first subset. A spatially varying two-phase segmentation process segments the first object from the bounding object within the second subset of pixels according to the location of each subject pixel within the second subset relative to pixels in the first subset of pixels. The first object segmentation is refined according to the subject pixel location relative to the segmented bounding object and to the first subset of pixels. A segmented image is formed according to the refined segmentation.
