Due to the limited sensitivity of the visual system to chrominance information, only rough approximation is required without a significant reduction in image quality.
The image compression works best on the luminance and chrominance color space.
Based on determining the smoke edge regions whose wavelet subband energies decrease with time, these regions are then analyzed along with their corresponding background regions with respect to their RGB and chrominance values to achieve real-time detection of smoke [14].
The results show that the viewers estimated that the best ratio between quality and compression level is achieved at compression level 8, which corresponds to approximate quality factors of 88,28 for luminance, and 90,19 for chrominance.
The common sense suggests that human skin appearance in photos is more controlled by the chrominance coordinates than the luminance one: the luminance could vary in a much larger interval than the chrominance.
Support for the JPEG2000 format in the YUV color space and decoding of JPEG2000 sources with separated luminance and chrominance provide increased interoperability with third-party JPEG2000-based solutions.
Every THX Certified Projection Screen is tested to ensure that the optical properties do not impact the chrominance, luminance or uniformity of the projected image.
The Y component denotes the luminance while U and V components denote the chrominance.

While Cb and Cr represent the chrominance components of a color image.
Chrominance and luminance filters limit dot crawl effects and tearing effects are managed using a dedicated tearing effect signal.
One signal is luminance used for brightness and other two signals are for chrominance which is used for colour quality.
