bit plane

(graphics)
(Or "bitplane") The memory in a graphic display device which holds a complete one-bit-per-pixel image. Several bit planes may be used in conjunction to give more bits per pixel or to overlay several images or mask one with another.

"Bit plane" may be used as a synonym for "bitmap", though the latter suggests the data itself rather than the memory and also suggests a graphics file format.

bit plane

(1) The sequence of bits for each pixel in a bitmap. The number of bits in the bit plane determines the number of colors that are displayed in the image. See bitmap and color depth.

(2) A segment of memory used to control an object, such as a color, cursor or sprite. Bit planes may be reserved parts of a common memory or independent memory banks each designed for one purpose.

This paper proposes an Enhanced Partial SPIHT algorithm that is based on the probability of significant coefficients within each bit plane and it also includes integer wavelet transform and region of interest coding, ie, ROI-IWT(Region Of Interest--Integer Wavelet Transform) and thereby improves the performance.

In CNLSPECK, the State information is kept in a fixed size array that corresponds to the array of coefficient values, with two bits per coefficient to enable fast scanning of the bit planes.
The SOFTIMAGE toolkit for Saturn will incorporate a set of extensions to SOFTIMAGE 3D, including Saturn file-output filters that make it easier to move output from SOFTIMAGE animation software to the game-platform file format; a 2-D paint retoucher to paint surfaces interactively and see results in 3-D, resulting in better-looking 3-D objects; an advanced, interactive color-reduction tool that allows users to switch from 24-bit space to an appropriate number of bit planes supported on the target platform; a Saturn file-format online viewer to quickly preview models created using SOFTIMAGE 3D in the Saturn file format; and enhanced UV texture mapping, for more memory-efficient representation of textures.
