The Resolution Myth
The optical resolution is a key parameter and major purchasing criteria for most users In a CCD based scanner each CCD element is mapped to the scanned original through a magnifying lens All CIS based scanners map the original directly 1:1 via a Selfoc lens If one inch of a document ́s surface illuminates 600 individual CCD elements then |

1 RAISR: Rapid and Accurate Image Super Resolution
Single Image Super Resolution (SISR) is the process of estimating a High-Resolution (HR) version of a Low-Resolution (LR) input image This is a well-studied problem which comes up in practice in many applications such as zoom-in of still and text images conversion of LR images/videos to high definition screens and more The |
C'est quoi la résolution d'une image ?
La résolution d'une image est le nombre de pixels par pouce qu'elle contient (1 pouce = 2.54 centimètres).
Elle est exprimée en "PPP" (points par pouce) ou DPI (dots per inch).
Plus il y a de pixels (ou points) par pouce et plus il y aura d'information dans l'image (plus précise).
Image File Sizes
The size of raster image files is positively correlated with the number of pixels in the image and the color depth (bits per pixel). Images can be compressed in various ways, however. A compression algorithmstores either an exact representation or an approximation of the original image in a smaller number of bytes that can be expanded back to its u
Image File Compression
There are two types of image file compression algorithms: lossless and lossy. Lossless compressionalgorithms reduce file size while preserving a perfect copy of the original uncompressed image. Lossless compression generally, but not always, results in larger files than lossy compression. Lossless compression should be used to avoid accumulating st
Major Graphic File Formats
Including proprietary types, there are hundreds of image file types. The PNG, JPEG, and GIF formats are most often used to display images on the Internet. Some of these graphic formats are listed and briefly described below, separated into the two main families of graphics: raster and vector. Raster images are further divided into formats primarily

C'est quoi la résolution d'une image ?
. Elle est exprimée en "PPP" (points par pouce) ou DPI (dots per inch).
. Plus il y a de pixels (ou points) par pouce et plus il y aura d'information dans l'image (plus précise).
Quelle est la bonne résolution d'une image ?
. Une résolution de 30 pixels par centimètre sera alors de 76 pixels par pouces ou 76 dpi.
Comment trouver la résolution d'une image ?
. Ainsi, pour une photo présentant 6 000 pixels sur la hauteur et 4 000 sur la largeur, la définition sera de : 6000 x 4000 px = 24 000 000 px, soit 24 mégapixels.
Comment définir la résolution ?
. Tout le monde a entendu parler des 300 ppp nécessaires à l'imprimeur.
. Cette valeur précise n'est pas indispensable.
. Il est admis qu'une résolution de 250 ppp est suffisante pour une impression de bonne qualité.
