Another important subject within computer vision is image segmentation. It is the process of dividing an image into different regions based on the characteristics of pixels to identify objects or boundaries to simplify an image and more efficiently analyze it. Segmentation impacts a number of domains, from the filmmaking industry to the field of medicine. For instance, the software behind green screens implements image segmentation to crop out the foreground and place it on a background for scenes that cannot be shot or would be dangerous to shoot in real life

La segmentation d'images constitue la base de nombreuses tâches de vision par ordinateur[,] comme la détection d'objets et la classification d'images. C'est une méthode qui consiste à diviser une image en sous-groupes. Cette division s'effectue habituellement en fonction du contour ou des limites visibles des objets dans une image afin d'en réduire la complexité. [...] La segmentation d'images a plusieurs utilités dans les domaines des véhicules autonomes, de l'analyse d'images médicales et d'images satellites, de la vidéosurveillance et d'autres tâches de reconnaissance et de détection.

OBS

deconvolution microscope : using the deconvolution microscope, researchers can see the locations of target molecules inside the cell. Seeing where glowing molecules reside within a cell is helpful for a range of research projects--from studies of how the distribution of various proteins changes during an organism's development to investigations of how administration of a drug alters the locations of certain proteins. The microscope, called DeltaVision, is manufactured by Applied Precision, based in Issaquah, Wash. It works by magnifying images and quantifying the intensity of light shed by the sample. The user specifies which colors of light are of interest. For instance, a user can program the microscope to report the intensity of a particular shade of green shining from the cytoplasm of a cell. After a researcher uses the microscope to make a series of optical slices through a specimen, the scope's computer "deconvolves" the images--in other words, it subtracts the out-of-focus light. Then the computer stacks together the images of the slices to reconstruct the original microscope sample. This gives researchers gh-resolution images of the sample's three-dimensional structure.

CONT

La microscopie de déconvolution à champ large est réalisée avec un microscope à fluorescence de facture classique. Les images obtenues sont donc «parasitées» par la fluorescence émise hors du plan de focalisation. Toutefois, un traitement informatique permet d'éliminer ce problème [...] Cette technique [...] permet d'utiliser des intensités d'illumination beaucoup plus faibles que celles qui sont mises en œuvre par la microscopie confocale.

[They] worked [together] to complete the most sophisticated of the four instruments-the DNA sequencer(1986). This machine rapidly determines the order of the four letters across the 24 strings of DNA by labeling the four DNA letters with laser-activated fluorescent dyes in red, green, blue or orange. The DNA sequences are then interpreted by a computer.

English

Subject field(s)
  • Printing Processes - Various
DEF

The process of making a separate electronic or photographic record of the amounts of each process colour of cyan, magenta, yellow or black needed to reproduce an original copy.

OBS

The record may be a photographic film made through red, green and blue separation filters or a computer file. A set of four separations, cyan, magenta, yellow and black, are required to reproduce an original image, since each of the four process colours must be represented. The separations may be made photographically using traditional methods or digitally using electronic scanners and computer programs. The original copy may be a transparency(slide), reflection photographic print, drawing, painting or printed reproduction.
