Image processing, color, metrics, and displays

Tutorials on turning sensor data into a displayed image, and on the color science and image-quality metrics used to evaluate it. See Image processing, Metrics, and Display for the conceptual pages, and Tutorials for the full topic index.

Image processing

• t_ip (source) Illustrates how to control the image-processing pipeline's demosaicking, color balance, and rendering steps.

• t_ipDemosaic (source) Compares demosaicking methods using the camera object.

• t_ipJPEGcolor (source) Reviews JPEG color compression.

• t_ipJPEGMonochrome (source) Introduces JPEG compression for a monochrome (single-channel) image.

Color science

• t_colorMatching (source) Tutorial on color matching and display rendering.

• t_colorChromaticity (source) Illustrates CIE xy chromaticity calculations and plots.

• t_colorEnergyQuanta (source) Converts between radiometric energy and photon-quanta units using Planck's relation.

• t_colorSpectrum (source) Uses color-matching principles to create the image of a spectrum (Psych 221).

Image-quality metrics

• t_metricsCielab (source) CIELAB color-error metric plots.

• t_metricsColor (source) Color metrics tutorial (Psych 221).
