how to display any image for 500 ms

how to write a code to display any image for 500 ms

Answer 1

@ANKIT MAURYA - you can try using a timer to stop displaying the image (or in this case, the figure for the image) after 0.5 seconds. For example,

function myTimerExample

close all;
hFig = figure;
sampleImage = uint8(randi(255,300,400,3));
image(sampleImage);

t = timer('TimerFcn', {@timerCallback, hFig}, 'StartDelay', 0.5, 'ExecutionMode', 'SingleShot');
start(t);

function timerCallback(hObject, hEvent, hFigure)

close(hFigure);

clc; clear all; close all;
% preapare data
xyloObj = VideoReader('traffic.avi');
nFrames = xyloObj.NumberOfFrames;
data = [];
for step = 1 : nFrames
    data{step} = read(xyloObj, step);       
end
% display by 500 ms
figure(1); clf;
for step = 1 : nFrames
    imshow(data{step}, []);
    title(sprintf('%03d %s', step, datestr(now,'mmmm dd, yyyy HH:MM:SS.FFF AM')));
    pause(500/1000);
end
