Scanner Access Now Easy (SANE) is an open-source application programming interface (API) that provides standardized access to any raster image scanner hardware (flatbed scanner, handheld scanner, video- and still-cameras, frame grabbers, etc.). The SANE API is public domain. It is commonly used on Linux.
An image scanner (often abbreviated to just scanner) is a device that optically scans images, printed text, handwriting, or an object and converts it to a digital image. The most common type of scanner used in the home and the office is the flatbed scanner , where the document is placed on a glass bed.
Cropping is the removal of unwanted outer areas from a photographic or illustrated image. The process usually consists of the removal of some of the peripheral areas of an image to remove extraneous visual data from the picture, improve its framing, change the aspect ratio, or accentuate or isolate the subject matter from its background.
Digital editors are used to crop images. Cropping creates a new image by selecting a desired rectangular portion from the image being cropped. The unwanted part of the image is discarded. Image cropping does not reduce the resolution of the area cropped. Best results are obtained when the original image has a high resolution.
3D scanning is the process of analyzing a real-world object or environment to collect three dimensional data of its shape and possibly its appearance (e.g. color). The collected data can then be used to construct digital 3D models. A 3D scanner can be based
3D scanning with Qlone requires the use of an included mat design. [ 7 ] [ 8 ] [ 9 ] The user prints the mat onto a sheet of paper, then places the object to be scanned in the centre of the mat. [ 10 ] [ 11 ] An augmented reality dome within the Qlone app guides the user through the subsequent scanning process.
A 2.35:1 film still panned and scanned to smaller sizes. At the smallest, 1.33:1 (4:3), nearly half of the original image has been cropped. Pan and Scan is a film editing methodology of adjusting widescreen film images to render them compatible for broadcast on 4:3 aspect ratio television screens.
Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data.
