Sensitometry is the scientific study of light-sensitive materials, especially photographic film. The study has its origins in the work by Ferdinand Hurter and Vero Charles Driffield (circa 1876) with early black-and-white emulsions. [1] [2] They determined how the density of silver produced varied with the amount of light received, and the ...

Tone mapped high-dynamic-range (HDR) image of St. Kentigerns Roman Catholic Church in Blackpool, Lancashire, England, UK. Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another to approximate the appearance of high-dynamic-range (HDR) images in a medium that has a more limited dynamic range.
Homomorphic filtering can be used for improving the appearance of a grayscale image by simultaneous intensity range compression (illumination) and contrast enhancement (reflection). Where, m = image, i = illumination, r = reflectance. We have to transform the equation into frequency domain in order to apply high pass filter.
Image compression. Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other ...
The pillars of Ashoka are a series of monolithic pillars dispersed throughout the Indian subcontinent, erected—or at least inscribed with edicts —by the 3rd Mauryan Emperor Ashoka the Great, who reigned from c.268 to 232 BC. [2] Ashoka used the expression Dhaṃma thaṃbhā ( Dharma stambha ), i.e. "pillars of the Dharma " to describe his ...
Hybrid log–gamma: HLG is a transfer function developed by NHK and BBC for HDR and offering some backward compatibility on SDR displays. HLG is a hybrid transfer function in which the lower half of the signal values use a gamma curve and the upper half of the signal values use a logarithmic curve. It is standardized in Rec. 2100.
