MATLAB YUV Toolbox ================== Scripts for manipulating YCbCr (also known as 'YUV') sequences. For comparing YUV sequences the Quality Assessment toolbox is required. For sequence rescaling and when rescaling chromas (e.g. conversion from 4:4:4 to 4:2:) Matlab Image Processing Toolbox function imresize is used. Functions --------- - **divide_seq** - Divides YUV sequence into segments - **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 Examples -------- **yuv\_import**, **yuv2rgb**, **yuv\_compare**: >> [Y, U, V] = yuv_import('FOREMAN_352x288_30_orig_01.yuv',[352 288],2); >> rgb = yuv2rgb(Y{1},U{1},V{1}); >> [PY, PU, PV]=yuv_compare('compressed.yuv','original.yuv',[352 288]);
