For YUV sequences comparison the Quality Assessment toolbox is required. For sequence rescaling and when rescaling chromas (e.g. conversion from 4:4:4 to 4:2:2) Matlab Image Processing Toolbox function imresize is used.
Functions:
divide_seq - Divides YUV sequence into segments
mm_seq - Converts video file into raw YCbCr format
read_floatframe - Reads and displays frame values stored as a stream of float numbers
rgb2yuv - Converts RGB to YUV
save_yuvframe - Saves selected frame from yuv sequence to image file
scale_seq - Scales YUV sequence
seq_frames - Returns the number of frames in YUV sequence file
shift_seq - Artificially shifts a sequence in a defined direction by any displacement
write_floatframe - Stores matrix in a file as a stream of float numbers
yuv2avi - Imports YUV sequence and saves it as AVI
yuv2rgb - Converts YUV to RGB
yuv_compare - Compares two YUV sequences by computing PSNR
yuv_export - Exports YUV sequence
yuv_import - Imports YUV sequence
yuv_range - Computes the range of samples in YUV sequence

I have been trying to use yuv2rgb function. I encountered the following error. Can any person help to resolve this?
Error using double
Conversion to double from cell is not possible.
Error in yuv2rgb (line 67)
yuv(:,:,1) = double(Y);

In function 'mm2yuv' remember change mmreader for VideoReader. For the rest works well, Thank you!

Some functions should be added to Matlab - this is one of them.
Post Scriptum: I am no longer common user of Mathworks flag product ( I do use GNU Octave-Cli + GNU-please-cit-Parallel ), but I do learn much from its exemplary documentation.

hi，there is no iq-measure.m file inside the yuv_compare.m, do you know where i could get the quality assessment toolbox to calculate the MSE & PSNR? thank you!

I encountered these problems.
>> [Y, U, V] = yuv_import('foreman_qcif.yuv',[352 288],2);
>> rgb = yuv2rgb(Y,U,V);
Error using double
Conversion to double from cell is not possible.
Error in yuv2rgb (line 67)
yuv(:,:,1) = double(Y);
>> [Y, U, V] = yuv_import('foreman_qcif.yuv',[352 288],0);
>> rgb = yuv2rgb(Y,U,V);
Error using double
Conversion to double from cell is not possible.
Error in yuv2rgb (line 67)
yuv(:,:,1) = double(Y);
>> numfrm = yuv2avi('foreman_qcif.yuv',[352 288],'foreman_qcif.avi','none',15,'YUV420_8');
Error using avifile
Too many input arguments.
Error in yuv2avi (line 39)
avi =
avifile(avifilename,'fps',fps,'quality',100,'colormap',gray(256),'compression',compression);
Please suggest the solution to read and convert into RGB video
