A system and method for performing real-time quality inspection of objects is disclosed. The system and method include a transport to move objects being inspected, allowing the inspection to be performed in-line. At least one optical acquisition unit is provided that captured optical images of the objects being inspected. The captured optical images are matched to CAD models of objects, and the matched CAD model is extracted. A laser with an illumination light beam has a wavelength in the violet or ultraviolet range then conducts scans of the objects, which are formed into three-dimensional point clouds. The point clouds are compared to the extracted CAD models for each object, where CTF are compared to user input or CAD model information and the object is determined to be acceptable or defective based on the extent of deviation between the point cloud and the CAD model.

A method of transforming the color appearance of a plurality of digital images includes receiving a plurality of digital images from a capture medium wherein each digital image includes a plurality of pixel values relating to at least three basic colors; calculating a color correction transform by using a non-linear adjustment that is independent of the digital images and which corrects an under-exposure condition as a function of the capture medium; and a linear functional relationship dependent upon the pixels of the basic colors, the linear functional relationship defining an exposure-level-dependent estimate of gray corresponding to the photographic response of the capture medium; and using the color correction transform to modify the pixels of the plurality of digital images wherein the pixels within a digital image are transformed with varying degrees of color modification as a function of exposure.

Color transformation for processing digital images

A system that sharpens an image by scaling high frequency residual components of an image stored in decomposed base and residual format. The scaling of the residuals is performed as a high resolution image is being reconstructed from the base and residual images. The scaling is combined with residual decompression into a single table look-up operation.

Method and apparatus for sharpening an image by scaling spatial residual

Digital reproductions of any size made from images scanned from film or taken by an electronic camera are optimally sharpened in a system-wide operation. The images are captured by an imaging device having an electronic imager and subsequently reproduced in a reproduction device, both imaging and reproduction devices having respective modulation transfer functions. Initially, the imaging device modulation transfer function and the reproduction device modulation transfer function are stored in separate devices. After an image is captured with the imaging device, a system modulation transfer function is generated from the imaging device modulation transfer function and the reproduction device modulation transfer function. Then a sharpening function is generated from the system modulation transfer function and the sharpening filter function is applied to the image captured by the imaging device in order to sharpen the image.

Automatic image sharpening in an electronic imaging system

A storage and retrieval mechanism for a digital image processing system employs a reduced capacity frame store in the playback device. A plurality of photographic images captured on a photographic recording medium are digitized for processing and subsequent display. Digitized images are stored on a compact disc. When the disc is inserted into a playback device for driving a color TV monitor, the playback device decodes header information representative of image orientation, so that the image will be read from the disc and stored in the reduced capacity frame store for subsequent read out and display in an upright orientation. A memory control mechanism employs a decimation/interpolation operator to interface the imagery data from the disc to the frame store.

Storage and retrieval of digitized photographic images

An image analysis and flicker filter control mechanism is incorporated into the image processing software of a photofinishing workstation for the purpose of analyzing the high frequency content of the image. As a result of this analysis, there is stored on a write once optical compact disc, in the header field associated with each image, an interlace 'flicker code' representative of the extent, if any, to which the vertical dimension of the image is to be subjected to a low pass filtering operation in the course of reading out the image from the disc for application to a playback device, such as a raster scan TV display. The flicker code may be a binary value code or a multiple bit value controls the degree of vertical lowpass filtering of only those images which exhibit interlace flicker, and only during playback onto interlaced TV displays, thereby reducing the flicker of an image reproduced by an interlaced TV display without reducing print sharpness.

Method and apparatus for adaptively reducing interline flicker of

A digital image processing system digitizes and stores photographic film images in their captured orientation on film, in order to obviate the need to physically rotate the film scanner relative to the film for vertical images, thereby significantly reducing the complexity and cost of the scanner. Instead, each stored image file has an associated presentation control file, which contains orientation and aspect ratio information, so that the image playback device will know how each image has been stored on the digital image database, such as a compact disc. When the disc is inserted into a playback device for driving an output display such as a color TV monitor, the playback device is readily able to decode the playback control information in the course of reading out the digitized image, so that the image will be displayed in an upright orientation and at the correct aspect ratio for the display.
