Color Feature- The color features are extracted from chrominance components namely Cb and Cr planes from YCbCr color space using mean and standard deviation.
The WFM7120 helps DFT optimize chrominance and luminance of the television shows it posts, including "Everybody Hates Chris" on CW and "Scrubs" on NBC.
For example, each decoder uses an adaptive 4H luminance and chrominance comb filter to separate video into its basic components, which results in sharper, more accurate images.
Patent Number 6,278,495 "Digital Comb Filter for Decoding Composite Video Signals" provides the technology base to dramatically improve long standing challenges associated with luminance and chrominance separation and resolution.
The TW2804 contains four 10-bit A/D and proprietary digital gain/clamp controllers and utilizes proprietary techniques for separating luminance & chrominance to reduce both cross luminance and cross-chrominance artifacts.
When combined with Premiere, DVRaptor RT2 provides users with 24 realtime video filters, such as Color Correction, Mosaic, Emboss, Picture-in-Picture, Chroma Key, Luma Key and Chrominance, as well as 30 simultaneous realtime title and graphic layers.
Video decoder that converts analog video signals into high-quality digital video signals -- 3D noise reducer that removes the noise in analog video signals and eliminates image flicker -- Anti-alias filter that eliminates noise exceeding the video signal bandwidth -- 3DY/C separator that accurately separates the luminance and chrominance in NTSC signals to reduce dot-crawl and cross-color artifacts and enable high-quality video capturing -- Support for all the major analog signal interface standards, including the SCART system used in Europe; the S system used in Japan; the component and composite systems used worldwide; PAL and SECAM, major TV broadcast signal standards used in Europe; and NTSC used in Japan and the U.
Up to 4 filter banks can be stored to allow separate shaping of the luminance and chrominance signals of each field of the video signal.
Analysis and readouts are generated for chrominance and luminance channels, separately or combined, at a variety of spatio-temporal resolutions and spatial frequency channels.
DVStorm features over 24 real-time filters, including color correction, mosaic, emboss, slow motion, picture-in-picture, chroma key, luma key and chrominance, and 15 transitions, including wipes, dissolves, slides, page curls and stretch.
Dynamic parameters provide the ability to adjust brightness, contrast, saturation, hue and sharpness, as well as luminance and chrominance temporal filters on the fly.
10-bit quantization steps are one quarter (1/4) the size of those generated with 8-bit quantization; therefore, the higher 10-bit precision does not produce the objectionable "banding" that occurs frequently with 8-bit quantization, particularly in scenes that have relatively large areas of nearly constant luminance and chrominance.
The LMH6704's low differential phase and gain specifications provide less luminance and chrominance distortion when driving composite video signals.
