Spectrum

Photometry Measuring light …

Colorimetry Modeling of color sensation Color addition Color subtraction Image processing (noise removal, edge detection, compression, inpainintg etc.) Bayer filter

Colorimetry CIE standard observer RGB color addition HSV CMYK color subtraction YIQ, YUV television broadcasting YCbCr digital television transmission, JPEG CIE gamut HSV gamut

Dichromatism: Colorimetry

The Human Visual System (HVS)

Vision Research Physiology Psychophysics Automatic Gain Control

Hermann’s Grid Vision Research

HVS is sensitive to: Local features. Spatial frequency (gratings). Contrast Sensitivity Function

Signal Representation How does the HVS represent images? Fourier series. Gabor functions. Wavelets

The Ear

Subjective Hearing Properties of the human auditory system are utilized in audio compression algorithms such as MP3.
