Block-matching and 3D filtering. Block-matching and 3D filtering (BM3D) is a 3-D block-matching algorithm used primarily for noise reduction in images. [ 1] It is one of the expansions of the non-local means methodology. [ 2] There are two cascades in BM3D: a hard-thresholding and a Wiener filter stage, both involving the following parts ...
The 5 free tetrominoes. A snapshot from a typical game of Tetris. A tetromino is a geometric shape composed of four squares, connected orthogonally (i.e. at the edges and not the corners). [ 1][ 2] Tetrominoes, like dominoes and pentominoes, are a particular type of polyomino. The corresponding polycube, called a tetracube, is a geometric shape ...
Apart from the other known console ports of Blockout, there were also two for NES: the first is an official unreleased prototype developed in 1990 by Technos Japan Corp. under the name "Block Out", while the second is an unauthorized clone programmed by Hwang Shinwei and published by both himself and RCM Group in 1989/1990 (titled 3D Block).

Adaptive scalable texture compression (ASTC) is a lossy block-based texture compression algorithm developed by Jørn Nystad et al. of ARM Ltd. and AMD. [1]Full details of ASTC were first presented publicly at the High Performance Graphics 2012 conference, in a paper by Olson et al. entitled "Adaptive Scalable Texture Compression".
Ionization energy is positive for neutral atoms, meaning that the ionization is an endothermic process. Roughly speaking, the closer the outermost electrons are to the nucleus of the atom, the higher the atom's ionization energy. In physics, ionization energy is usually expressed in electronvolts (eV) or joules (J).
3D Dot Game Heroes. 3D Dot Game Heroes[ a] is an action role-playing video game developed by Silicon Studio for the PlayStation 3. The game is presented using voxel -based graphics in a 3D environment to emulate the 2D graphics of earlier video games. [ 2] The game was published in Japan by FromSoftware in November 2009, and in North America ...
After this element, the filled 3d subshell effectively withdraws from chemistry and the subsequent trend looks much like trends in the periods 2 and 3. The p-block elements of period 4 have their valence shell composed of 4s and 4p subshells of the fourth ( n = 4 ) shell and obey the octet rule .
