Generate a scene from an typical image (RGB) file.

This tutorial generates ISET scenes from RGB file on different displays. It also shows the three different display gamuts as well as approximate renderings of the images.

Create scene from file

Init data file path

imgFileName = 'macbeth.tif';
dispOLEDFile = 'OLED-Sony.mat';
dispLCDFile = 'LCD-Apple.mat';
dispCRTFile = 'CRT-Dell.mat';

Create scene from file for OLED

% The illuminant is set to be the white point of the monitor
sceneA = sceneFromFile(imgFileName,'rgb',[],dispOLEDFile);
sceneA = sceneSet(sceneA,'name','Scene on OLED');
ieAddObject(sceneA); sceneWindow;

Show scene on LCD

sceneB = sceneFromFile(imgFileName,'rgb',[],dispLCDFile);
sceneB = sceneSet(sceneB,'name','Scene on LCD');
ieAddObject(sceneB); sceneWindow;

Show scene on CRT

sceneC = sceneFromFile(imgFileName,'rgb',[],dispCRTFile);
sceneC = sceneSet(sceneC,'name','Scene on CRT');
ieAddObject(sceneC); sceneWindow;

Compare the three images

imageMultiview('scene', 1:3, true);

Compare the gamuts of the three monitors

d = displayCreate(dispOLEDFile);
displayPlot(d,'gamut');
title('OLED')

d = displayCreate(dispLCDFile);
displayPlot(d,'gamut');
title('LCD')

d = displayCreate(dispCRTFile);
displayPlot(d,'gamut');
title('CRT')
