A fast parallel coloring of planar graphs with five colors
Information Processing Letters, 1987Abstract We have shown that coloring a planar graph with five colors is in complexity class NC. The crux of the algorithm is our ability to find a large set of independent vertices and change the colors of their neighbors so that each independent vertex can color itself. This improves the result of [2] which colors a planar graph with eight colors. A

cFAST: A fast color feature detector
2015 International Conference on Image Processing Theory, Tools and Applications (IPTA), 2015By extending the basic idea of FAST it is possible to create a detector that can operate directly on a RGB color image and on it detect a higher number of features. The higher number of points and the simplification of the metric put us in the position to impose an additional condition on the keypoints.

Fast local color transfer via dominant colors mapping
ACM SIGGRAPH ASIA 2010 Sketches, 2010Color transfer is an image editing technique which arises various applications, from daily photo appearance enhancement to movie post-processing. An ideal color transfer algorithm should keep the scene from the source image and apply the color style of the target image.

Fast Algorithm for HDR Color Conversion
2016 Data Compression Conference (DCC), 2016The paper addresses a problem of perceptual artifacts that appear in Y'CbCr non-linear luminance 4:2:0 HDR video. A computationally inexpensive method is proposed for converting the 4:4:4 HDR video to Y'CbCr 4:2:0 nonconstant luminance format. The method removes artifacts in areas with saturated colors.

Fast Color Change with Photochromic Fused Naphthopyrans
The Journal of Organic Chemistry, 2015Photochromic molecules can reversibly develop color upon irradiation with UV light. These smart molecules, mainly in the naphthopyran family, have been applied with success to ophthalmic lenses that darken quickly under sunlight and revert to the uncolored state after several minutes in the dark.

Fast Trellis-Coded Color Quantization of Images
Real-Time Imaging, 2002Summary: We examine color quantization of images using trellis-coded quantization (TCQ) in both the RGB domain and YUV domain. Together with a simple dithering scheme, an eight-bit trellis-coded color quantizer reproduces images that are visually indistinguishable from the 24-bit originals.

Fast reversible coding and indexing of colorations
Computing, 1976Given a non-branched tree withn vertices. Then, by ann-g-coloration we understand a partition of the set of vertices into no more thang classes, such that adjacent vertices belong to different classes. Supposed the set\(\mathfrak{S}\) of alln-g-colorations (for givenn andg) is lexicographically ordered, here are given two algorithms: the first directly

Fast color image processing using quantized color instruction set
Proceedings ITCC 2003. International Conference on Information Technology: Coding and Computing, 2004The paper describes the Quantized Color Pack eXtension (QCPX) instruction set that can accelerate color-image processing applications. QCPX employs heterogeneous-subword-parallel instructions, which utilize the microprocessor's 16-bit wide datapaths to process a packed, quantized 16-bit color data type in YCbCr (Y: luminance, Cr and Cb: chrominance ...
