Imaging performance taxonomy

Standardization of Image Quality Analysis – ISO 19264

“…The reason for this division is the different patterns in the test chart used to measure the aspects. A slightly different approach is the imaging performance taxonomy [12] that divides the image quality aspects by their origin.…”

A critical review of the slanted-edge method for color SFR measurement

“…The spatial frequency response (SFR) of a digital image acquisition system is an objective measure of image quality that describes an imaging system's ability to capture or maintain the relative radiometric contrast of increasingly fine sinusoidal patterns [1]. The SFR neatly encapsulates the influence of the optical elements, the pixel MTF and the camera electronics, on image quality.…”

A new quality assessment and improvement system for print media

“…Current research carried out in the industry sector focuses on methodologies to measure the analog-to-digital conversion quality of a digitization device using various test targets [2][3][4][5][6][7][8][9]. Among other goals industry research aims at identifying evaluation methodologies and quantifiable parameters (like modulation transfer function, noise, sharpness etc.)…”

“…is of similar importance. Recent research approaches in this field are almost exclusively carried out by the industrial sector [2][3][4][5][6][7][8][9] or the cultural sector [1,[10][11][12][13] while there are only few publications from the field of basic research dating back to the 1990s [14][15][16] including a review of results related to image quality research [17].…”

“…• Color fidelity • Spatial resolution • Contrast/brightness • Image geometry • Sharpness • Noise and many other parameters [3] have to be faithfully conveyed by the analog-to-digital converter (e.g., camera or scanner) [4][5][6] and further processing steps in the digital domain. In addition, the detection of unwanted objects like dust, fingers (belonging to the digitization operator) etc.…”
