It is also important when attempting sub-pixel resolution to keep image noise to a minimum. This, in the case of a stationary scene, can be measured from a time series of images. Appropriate pixel averaging, through both time (for stationary images) and space (for uniform regions of the image) is often used to prepare the image for sub-pixel ...
Subpixel rendering is a method used to increase the effective resolution of a color display device. It takes advantage of each pixel 's composition of individually addressable red, green, and blue components adjacent on the display matrix, called subpixels , and uses them as rendering units instead of pixels.
Magnified image of the AMOLED screen on the Google Nexus One smartphone using the RGBG system of the PenTile matrix family. PenTile RGBG layout used in AMOLED and plasma [8] displays uses green pixels interleaved with alternating red and blue pixels. The human eye is most sensitive to green, especially for high resolution luminance information ...
The result is often represented in terms of sets of (connected or unconnected) coordinates of the image points where features have been detected, sometimes with subpixel accuracy. When feature extraction is done without local decision making, the result is often referred to as a feature image. Consequently, a feature image can be seen as an ...
Resolution and localization: True resolution involves the distinction of whether a target, e.g. a star or a spectral line, is single or double, ordinarily requiring separable peaks in the image. When a target is known to be single, its location can be determined with higher precision than the image width by finding the centroid (center of ...
U.S. patent 6,225,973 – Mapping samples of foreground/background color image data to pixel sub-components; U.S. patent 6,243,070 – Method and apparatus for detecting and reducing color artifacts in images; U.S. patent 6,393,145 – Methods apparatus and data structures for enhancing the resolution of images to be rendered on patterned ...
Morphological antialiasing (MLAA) is a technique for minimizing the distortion artifacts known as aliasing when representing a high-resolution image at a lower resolution. Contrary to multisample anti-aliasing (MSAA), which does not work for deferred rendering , MLAA is a post-process filtering which detects borders in the resulting image and ...
General scheme of content-based image retrieval. Content-based image retrieval, also known as query by image content and content-based visual information retrieval (CBVIR), is the application of computer vision techniques to the image retrieval problem, that is, the problem of searching for digital images in large databases (see this survey [1] for a scientific overview of the CBIR field).
