The CPUs in modern computers, video game consoles, and mobile devices are fast enough that bitmaps can be drawn into a frame buffer without special hardware assistance. Beyond that, GPUs can render vast numbers of scaled, rotated, anti-aliased, partially translucent, very high resolution images in parallel with the CPU.
Pixel art [note 1] is a form of digital art drawn with graphical software where images are built using pixels as the only building block. [2] It is widely associated with the low-resolution graphics from 8-bit and 16-bit era computers, arcade machines and video game consoles, in addition to other limited systems such as LED displays and graphing calculators, which have a limited number of ...
The form of dimetric projection commonly used in video games and pixel art. Only two of the angles separating the x, y and z axes are the same, and only some of the lengths of the cube's edges are equal. The expression arctan(sin(30°)) is equal to ≈26.565° and forms a 2:1 pixel ratio.
The images have been rigorously collected during oceanic explorations and human-robot collaborative experiments, and annotated by human participants. Images with pixel annotations for eight object categories: fish (vertebrates), reefs (invertebrates), aquatic plants, wrecks/ruins, human divers, robots, and sea-floor. 1,635 Images Segmentation 2020
CIFAR-10 is a set of images that can be used to teach a computer how to recognize objects. Since the images in CIFAR-10 are low-resolution (32x32), this dataset can allow researchers to quickly try different algorithms to see what works. CIFAR-10 is a labeled subset of the 80 Million Tiny Images dataset from 2008, published in 2009. When the ...
Standard ZX Spectrum palette with dithering, in pixel art. The low per-pixel bit depth of only one bit per pixel has urged the graphic artists (e.g. at ZX-Art) to resort to various dithering techniques. Dithering works very well with CRT TV sets of the era, because analog televisions employ a high amount of blur in both the horizontal and ...
A very important characteristic of a binary image is the distance transform. This gives the distance of every set pixel from the nearest unset pixel. The distance transform can be efficiently calculated. It allows efficient computation of Voronoi diagrams, where each pixel in an image is assigned to the nearest of a set of points. It also ...
If the pixel depth is 16 bits, the topmost bit is reserved for transparency. For a pixel depth of 24 bits, each pixel is stored with 8 bits per color. A 32-bit pixel depth defines an additional 8-bit alpha channel. Image type 3 and 11: The image data is a direct representation of grayscale data. The pixel depth is 8 bits for images of this type.
