This is a 21 class land use image dataset meant for research purposes. There are 100 images for each class. 2,100 Image chips of 256x256, 30 cm (1 foot) GSD Land cover classification 2010 [175] Yi Yang and Shawn Newsam SAT-4 Airborne Dataset Images were extracted from the National Agriculture Imagery Program (NAIP) dataset.
A bitmap color font for the Amiga OS. Digital bitmap fonts (and the final rendering of vector fonts) may use monochrome or shades of gray.The latter is anti-aliased.When displaying a text, typically an operating system properly represents the "shades of gray" as intermediate colors between the color of the font and that of the background.
Phototypesetting machines project characters onto film for offset printing. Prior to the advent of phototypesetting, mass-market typesetting typically employed hot metal typesetting – an improvement introduced in the late 19th century to the letterpress printing technique that offered greatly improved typesetting speed and efficiency compared to manual typesetting (where every sort had to be ...
Video of the process of scanning and real-time optical character recognition (OCR) with a portable scanner. Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene photo (for example the text on signs and ...
The MNIST database (Modified National Institute of Standards and Technology database [1]) is a large database of handwritten digits that is commonly used for training various image processing systems. [2] [3] The database is also widely used for training and testing in the field of machine learning.
Many of the techniques of digital image processing, or digital picture processing as it often was called, were developed in the 1960s, at Bell Laboratories, the Jet Propulsion Laboratory, Massachusetts Institute of Technology, University of Maryland, and a few other research facilities, with application to satellite imagery, wire-photo standards conversion, medical imaging, videophone ...
The glyph outline data in an OpenType font may be in one of two formats: either TrueType format outlines in a 'glyf' table, or Compact Font Format (CFF) outlines in a 'CFF ' table. (The table name 'CFF ' is four characters long, ending in a space character.) CFF outline data is based on the PostScript language Type 2 font format. However, the ...
Many families of Metafont fonts are set up so that the main source file for a font only defines a small number of design parameters (x-height, em width, slant, vertical stroke width, etc.), then calling a separate source file common for a whole range of fonts to actually draw the individual glyphs; this is the meta aspect of the system.
