Hello,
I have a video that we will call 'x' and some images that we will call 'output_cross_alfa' and 'output_cross_Nalfa'.
My goal is to make the sum of 'x' with 'output_cross_alfa' in the even frames, and in the odd frames the sum of 'x' is done with 'output_cross_Nalfa'. The final video should be:
frame1 = frame1 + output_cross_Nalfa;
frame2 = frame2 + output_cross_alfa;
frame3 = frame3 + output_cross_Nalfa;
frame4 = frame4 + output_cross_alfa;
……
To do this I used this code:
for ii = 1: 2: length (imageNames) for kk = 2: 2: length (imageNames) img1 = im2single (imread (fullfile (workingDir, 'images', imageNames {ii}))); image_2 = im2single (img1 + output_cross_alfa); img2 = im2single (imread (fullfile (workingDir, 'images', imageNames {kk}))); image_1 = im2single (img2 + output_cross_Nalfa); output = uint8 (image_par + image_par); writeVideo (outputVideo, output); endend
But I only get screenshots in black and gray when representing it.
To represent it I use this:
shuttleAvi = VideoReader (fullfile (workingDir, 'shuttle_out.avi'));ii = 1;while hasFrame (shuttleAvi) mov (ii) = (im2frame (readFrame (shuttleAvi))); ii = ii + 1;endfigure, imshow (mov (1) .cdata, 'Border', 'tight');movie (mov, 1, shuttleAvi.FrameRate);
And I have no idea what the failure may be.
