  • Image editing
    Raster images are stored in a computer in the form of a grid of picture elements, or pixels.
  • Color vision
    Color vision is the ability of an organism or machine to distinguish objects based on the wavelengths (or frequencies) of the light they reflect, emit, or transmit.
  • Framebuffer
    A framebuffer (frame buffer, or sometimes framestore) is a portion of RAM containing a bitmap that is used to refresh a video display from a memory buffer containing a complete frame of data.
  • Gabor filter
    In image processing, a Gabor filter, named after Dennis Gabor, is a linear filter used for edge detection.
  • Supersampling
    Supersampling is a spatial anti-aliasing method, i.
  • Convolution
    In mathematics (and, in particular, functional analysis) convolution is a mathematical operation on two functions (f and g); it produces a third function, that is typically viewed as a modified version of one of the original functions, giving the integral of the pointwise multiplication of the two functions as a function of the amount that one of the original functions is translated.
  • Image processing
    In imaging science, Image Processing is processing of images using mathematical operations by using any form of signal processing for which the input is an image, a series of images, or a video, such as a photograph or video frame; the output of image processing may be either an image or a set of characteristics or parameters related to the image.
  • Medical imaging
    Medical imaging is the technique and process of creating visual representations of the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology).
  • Monochrome
    Monochrome describes paintings, drawings, design, or photographs in one color or values of one color.
  • Dither
    Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images.
  • Otsu's method
    In computer vision and image processing, Otsu's method, named after Nobuyuki Otsu (大津展之 Ōtsu Nobuyuki), is used to automatically perform clustering-based image thresholding, or, the reduction of a graylevel image to a binary image.
  • Image scaling
    In computer graphics and digital imaging, scaling refers to the resizing of a digital image.
  • Spherical basis
    In pure and applied mathematics, particularly quantum mechanics and computer graphics and their applications, a spherical basis is the basis used to express spherical tensors.
  • Visual computing
    Visual computing is a generic term for all computer science disciplines handling with images and 3D models, i.
  • Color layout descriptor
    A color layout descriptor (CLD) is designed to capture the spatial distribution of color in an image.
  • Signal-to-noise ratio (imaging)
    The signal-to-noise ratio (SNR) is used in imaging as a physical measure of the sensitivity of a (digital or film) imaging system.
  • Pixel aspect ratio
    Pixel aspect ratio (often abbreviated PAR) is a mathematical ratio that describes how the width of a pixel in a digital image compares to the height of that pixel.
  • Richardson–Lucy deconvolution
    The Richardson–Lucy algorithm, also known as Lucy–Richardson deconvolution, is an iterative procedure for recovering a latent image that has been blurred by a known point spread function.
  • Sub-pixel resolution
    In digital image processing, sub-pixel resolution can be obtained in images constructed from sources with information exceeding the nominal pixel resolution of said images.
  • Tensor operator
    In pure and applied mathematics, quantum mechanics and computer graphics, a tensor operator generalizes the notion of operators which are scalars and vectors.
  • Halide (programming language)
    Halide is a computer programming language designed for writing image processing code that takes advantage of memory locality, vectorized computation and multi-core CPUs and GPUs.
  • Anisotropic diffusion
    In image processing and computer vision, anisotropic diffusion, also called Perona–Malik diffusion, is a technique aiming at reducing image noise without removing significant parts of the image content, typically edges, lines or other details that are important for the interpretation of the image.
