... fundus autofluorescence(FAF) imaging, which detects autofluorescent material, i. e., lipofuscin, in the retinal pigment epithelium(RPE). Fluorophores detectable with this imaging method may also occur anterior or posterior to the RPE cell monolayer. Excessive lipofuscin accumulation in the RPE is a common downstream pathogenic pathway in various monogenetic and complex retinal diseases including age-related macular degeneration. The accumulated lipofuscin produces a signal that is captured in the FAF image allowing in vivo mapping of metabolic changes in the RPE.  6, record 1, English, - fundus%20autofluorescence%20imaging

Optical coherence tomography(OCT) is a non-contact imaging technique which generates cross-sectional images of tissue with high resolution. Therefore it is especially valuable in organs, where traditional microscopic tissue diagnosis by means of biopsy is not available—such as the human eye. Since OCT is completely noninvasive, it provides in vivo images without impacting the tissue that is imaged. Fast scanning rates and quick signal processing allows for image visualization in real time and at video rate.... the resolution of OCT is much higher than that of other medical imaging methods like ultrasound or magnetic resonance imaging(MRI).  3, record 2, English, - optical%20coherence%20tomography

Optical coherence tomography angiography(OCTA) is a noninvasive technique that can detect blood flow signal in retinal and choroidal vessels using motion contrast. It compares the decorrelation signal(differences in the backscattered OCT [optical coherence tomography] signal intensity) between sequential OCT B-scans taken at the same cross-section; thus, yielding maps of vascular flow.... Numerous studies described how to automatically detect and classify retinal disorders(e. g., diabetic retinopathy [DR]).

synthetic aperture radar; SAR :[A] synthetic aperture radar(SAR) is a side-looking imaging radar usually operating on either an aircraft or a spacecraft. The radar transmits a series of short, coherent pulses to the ground producing a footprint whose size is inversely proportional to the antenna size, its aperture. Because the antenna size is generally small, the footprint is large and any particular target is illuminated by several hundred radar pulses. Intensive signal processing involving the detection of small Doppler shifts in the reflected signals from targets to the moving radar produces a high resolution image that is equivalent to one that would have been collected by a radar with a much larger aperture.  4, record 9, English, - C%2Dband%20synthetic%20aperture%20radar

The image processing consisted in generating intensity images and one coherence image. To facilitate their analysis and interpretation, a coloured composition has been created with the results. This composition is obtained by adding the coherence image in red, the average of both images phase intensities in green and the difference between these phase intensities in blue. As such, a high coherence level(value close to 1) appears in red and indicates a very good phase correlation between the two images, a consequence of the various mechanisms of radar signal scattering and of the lack of change which could affect the target. On the contrary, a weak coherence level(value tending to 0) appears in black and indicates a movement in these zones during the 24 hours interval which separated the two image shots. Lastly, the white spots correspond to areas with a strong radar signal backscattering i. e. with zones of hills or vegetation.  3, record 12, English, - colour%20composition

Scanning transmission electron microscopy(STEM) combines the principles of transmission electron microscopy and scanning electron microscopy and can be performed on either type of instrument. Like TEM [transmission electron microscopy], STEM requires very thin samples and looks primarily at beam electrons transmitted by the sample. One of its principal advantages over TEM is in enabling the use of other signals that cannot be spatially correlated in TEM, including secondary electrons, scattered beam electrons, characteristic X-rays, and electron energy loss. Like SEM [scanning electron microscopy], the STEM technique scans a very finely focused beam of electrons across the sample in a raster pattern. Interactions between the beam electrons and sample atoms generate a serial signal stream, which is correlated with beam position to build a virtual image in which the signal level at any location in the sample is represented by the gray level at the corresponding location in the image. Its primary advantage over conventional SEM imaging is the improvement in spatial resolution.  3, record 15, English, - scanning%20transmission%20electron%20microscopy

The methods find use in a variety of applications such as acoustic imaging of geological structures, SONAR imaging of sub-sea objects, and medical ultrasound imaging. The methods are based on processing of the received signal from transmitted dual frequency band acoustic pulse complexes with overlapping high and low frequency pulses.

The imaging system has a linear detector array(usually of the CCD type) consisting of a number of detector elements(6000 elements in SPOT HRV). Each detector element projects an "instantaneous field of view(IFOV) "on the ground. The signal recorded by a detector element is proportional to the total radiation collected within its IFOV. At any instant, a row of pixels are formed. As the detector array flies along its track, the row of pixels sweeps along to generate a two-dimensional image.  2, record 30, English, - linear%20detector%20array

Pour éviter des déformations géométriques dans les angles des écrans des micro-ordinateurs, l'image n'occupe qu'environ 90 % de la surface du tube cathodique.

Dans un certain nombre de dispositifs de conversion vidéo, cet écart est conservé hors de la transformation des images informatiques en images vidéo. Pour des applications de type création graphique, animation, incrustation d'images informatiques, cet écart est très gênant. Certains constructeurs permettent alors, de choisir le format d'affichage vidéo de l'image. Un premier réglage (mode «underscan») permet de conserver l'image informatique dans sa taille initiale.

Envisat's ASAR [Advanced Synthetic Aperture Radar] instrument is the first permanent spaceborne radar to incorporate dual-polarisation capabilities-the instrument can transmit and receive signals in either horizontal or vertical polarisation. This Alternating Polarisation(AP) mode can improve the capability of a SAR instrument to classify different types of terrain. Because the reflective properties of a surface are dependant on the polarisation of the incoming radar signal, the use of more than one type of polarisation provides valuable extra information. The ASAR AP mode provides two simultaneous images(or channels) of the same scene taken with different radar polarisation options. Since the radar can transmit and receive in both the horizontal(H) and vertical(V) polarisations, researchers can create image pairs, with possible combinations, HH&VV... HH&HV and VV&VH. A cross-polarisation option employs a channel in which the polarisation signal transmitted by the spacecraft is received on a different polarisation, i. e. transmitted using a horizontal polarisation and received on the vertical for an HV combination, or the reverse for a VH combination.  3, record 39, English, - advanced%20synthetic%20aperture%20radar

Au cinéma l'image est chimique (pellicule argentique) alors qu'en vidéo elle est électronique. Et cette image peut avoir du souffle. Ce souffle, qui se manifeste par une granulation vidéo excessive et un fourmillement de points, est appelé bruit image. Il peut venir de la source (DVD, LD, K7...) comme du lecteur. Le rapport signal/bruit, exprimé en dB, traduit le niveau résiduel du souffle. Ce rapport doit être aussi élevé que possible.  1, record 47, French, - bruit%20image
