Given a color image that was quantized in some hidden color space (termed compression color space) during previous JPEG compression, we aim to estimate this unknown compression color space from the image. This knowledge is potentially useful for color image enhancement and JPEG re-compression. JPEG quantizes the discrete cosine transform (DCT) coefficients of each color plane independently duri...
Abstract. We report a calculation reduction method for color computer-generated holograms (CGHs) using color space conversion. Color CGHs are generally calculated on RGB space. In this paper, we calculate color CGHs in other color spaces: for example, YCbCr color space. In YCbCr color space, a RGB image is converted to the luminance component (Y), blue-difference chroma (Cb) and red-difference ...
The study of color perception in humans is an important ongoing research which currently mainly relies on psychophysical studies. Most psychophysical studies are prune to limitations which can highly reduce the scalability and repeatability of their experiments, cause over-fitting, and fail to fully engage subjects in performing the given tasks. Gamification is becoming a popular approach in ob...
