摘要： A robust means of watermarking a digitized image with a highly random sequence of pixel brightness multipliers is presented. The random sequence is formed from ‘robust-watermarking-parameters’ selected and known only by the marker and/or the marking entity. A watermarking plane is generated which has an element array with one-to-one element correspondence to the pixels of the digitized image being marked. Each element of the watermarking plane is assigned a random value dependent upon a robust random sequence and a specified brightness modulation strength. The so generated watermarking plane is imparted onto the digitized image by multiplying the brightness value or values of each pixel by its corresponding element value in the watermarking plane. The resulting modified brightness values impart the random and relatively invisible watermark onto the digitized image. Brightness alteration is the essence of watermark imparting. Detection of an imparted watermark requires knowing the watermarking plane with which the watermark was imparted. Regeneration of the watermarking plane requires knowledge of the robust-marking-parameters used in its formulation. This is generally only known to the marker and/or marking entity. Once regenerated the watermarking plane is used together with a verifying image located in a ‘visualizer’ to demonstrate the existence of the watermark.

摘要： This invention provides methods, apparatus and article of manufacture used as a countermeasure to image distorting. The present invention involves automatically detecting the presence of distortion in a presumed distorted image, measuring the magnitude and type of distortion, and finally creating a realigned image. Once image distortion is removed, conventional invisible watermark extraction methods are employed to extract the watermark from the realigned image. The automatic method does not depend on a process of visually examining a composite image and recording the coordinates of pixel locations closest to common image features in a distorted image and reference image. Generally, the presumed distorted image is resized to the same size as the reference image. Reference centers at at least three distinct points that do not form a straight line are selected. At each reference center, a sub-image is excised. Pairs of sub-images, one excised from the reference image and the other excised from the distorted image, having the same reference center are used in the process of removal of the distortion.

摘要： The present invention provides methods and apparatus for the color calibration of displays. These methods are particularly useful for displays having properties different than those associated with cathode ray tubes (CRT). Some displays, for example liquid crystal displays (LCD), have a high luminance black, the chromas of their primaries are not independent of their luminance levels, the intensities of their primaries are not strictly monotonically increasing with respect to their RGB levels, the color additivity of their subpixels is affected by crosstalk or leakage and their color measurements are dependent on the view angle of the observer. Therefore, the usage of CRT methods is deficient for such displays. The methods and apparatus of the present invention overcome several deficiencies generally found in non-CRT display devices by employing techniques associated with the use of restricted ranges for the primaries, subtracting the color black from all color measurements, forming a modified display matrix and/or creating tables which correct errors due to the non-linearities or color leakages of these display devices. These enable images to be processed using algorithms of different complexity and precision.

摘要： A robust means of watermarking a digitized image with a highly random sequence of pixel brightness multipliers is presented. The random sequence is formed from ‘robust-watermarking-parameters’ selected and known only by the marker and/or the marking entity. A watermarking plane is generated having an element array with one-to-one element positional correspondence with the pixels of the digitized image being marked. Each element of the watermarking plane is assigned a random value dependent upon a robust random sequence and a specified brightness modulation strength. The so generated watermarking plane is imparted onto the digitized image by multiplying the brightness value or values of each pixel by its corresponding element value in the watermarking plane. The resulting modified brightness values impart the random and relatively invisible watermark onto the digitized image. Brightness modulation is the essence of watermark imparting. Detection of an imparted watermark requires knowing the watermarking plane with which the watermark was imparted.

Once regenerated, the watermarking plane is used together with a verifying image located in a ‘visualizer’ to demonstrate the existence of the watermark. The process of watermark detection is enhanced by application of a blurring filter to the marked image before detection is attempted.

摘要： This invention provides methods and apparatus as a countermeasure to image distorting. Several image distorting algorithms have been developed that are intended to attack and obliterate robust relatively invisible image watermarks. These algorithms modify a watermarked image so subtly by geometric distortion that the modification is essentially unnoticeable to a human observer. However, their effect on imbedded relatively invisible watermarks can be devastating, often successfully rendering them unextractable. A method of the present invention involves detecting the presence of distortion in a presumed distorted image, then measuring the magnitude and type of distortion, and finally creating a reoriented image from which the measured distortion has been removed. Once image distortion is removed, conventional invisible watermark extraction methods can be employed to extract the watermark from the reoriented image.

摘要： Print verification is done by scanning the printed copies, thereby forming a stream of scanned images of the specific pages. Digitized images from the stream are then spatially aligned page by page, line by line and pixel (pel) by pixel (pel) with corresponding digitized images in a stream of source images. The source and scanned images are compared to find pel sequences that are different. These differences represent defects in the printed copies.

摘要： A system and process by which misregistration among the pixel components of the several color planes of a color image can be substantially eliminated is presented. In an embodiment, the physical object which comprises the test scene is represented as having features that are uniform squares of alternating black and white color arranged. The digitized color image of the test scene is employed to make measurements of misregistration of scene features in its color planes. A process by which misregistration among the several color planes is measured, and substantially eliminated, is made up of three parts. First, one of the color planes is chosen as a reference plane. The remainder of the color planes are called secondary planes. The relative misregistration of image features in the secondary planes relative to corresponding image features in the reference plane are measured at dispersed pixel locations in the reference plane. Secondly, for each of the secondary planes, an interpolated approximation of the offset of its scene features is computed for each pixel location in the reference plane by using the measured offsets. Thirdly, the color components of each pixel in each of the secondary planes are interpolated using those offsets and the color component values from the neighboring pixels in the same secondary color plane. The interpolated color component values derived from each of the secondary planes are used to form revised color planes and the reregistered image.
