abekas2yuv  The software converts the abekas file format into the YUV progressive
format. The software is the same that you can download from here

burst_counter  This Matlab script provides the average burst length of given error pattern specified as a string of characters '0' and '1'

burst_counter  It provides the same results of the Matlab scripts burst_counter (see above) but it is implemented in C

dct_frame  This Matlab script performs the DCT computation over a
nonoverlapped grid of disjoint blocks

gilbert_model  This Matlab script computes an error pattern with a given burst length
and packet loss rate generated according to a two states Gilbert model.
For further details see: E. N. Gilbert, “Capacity of a burstnoise channel,” Bell System Technical Journal, vol. 39, pp. 1253–1266, September 1960

h264_quarter_pel
 This Matlab script performs the quarter pixel frame upsampling as
specified by the H.264/AVC video coding standard. The script also
performs frame edge padding to allow out of boundary motion vectors

luma_grabber  This Matlab script returns a matrix containing the
luminance component of the frame numbers specified as input parameters

psnr_calculation  This Matlab script returns the PSNR between the original YUV video
sequence and the decoded one. The PSNR is computed over the luminance
and the two chromatic components

transmitter_simulator
 This C++ program simulates the transmission of an H.264/AVC bitstream
through an error prone channel which drops coded packets according to a
given packet loss rate

yuv2rgb  This Matlab script performs the YUV to RGB conversion according to what described here

yuv422to420converter
 This Matlab script performs the spatial downsampling of the chrominance components of one YUV video sequence file

modified_h264_decoder
 This software is a modified version of the H.264/AVC encoder/decoder reference software provided by JVT
(version JM12.3). The encoder allows to avoid intra macroblock
prediction in inter coded slices. Conversely, the decoder allows to dump
some useful data (e.g. motion vectors, coding modes, prediction
residuals, etc.) to perform some further analysis. WARNING: The current decoder works only with bitstreams coded with the Baseline
profile

spatiotemporal_index  This Matlab script computes the spatial and temporal indexes according
to the ITUR specifications provided in the following document:
"Subjective video quality assessment methods for multimedia
applications", Recommendation ITUR, P 910, September 1999.
Updated version (May 2014) which:
 Doesn't require the Image Processing Toolbox to be installed
 Fixes a small discrepancy between the ITU specification and zero padding for SI
 Handles different bit depths with scaling of final values in the 8 bit depth range

image_class  A C++ class which implements a 2D image with several useful
functionalities for storing, accessing, etc. The class also provides
several overloaded operators to simplify operations like: sum,
subtraction, multiplication, etc. between two images

H.264/AVC forward 4x4 DCT & quantization
 A Matlab MEX function which performs the 4x4 Discrete Cosine Transform
(DCT) and quantization as specified in the H.264/AVC video coding
standard

H.264/AVC inverse quantization & inverse4x4 DCT
 A Matlab MEX function which performs the 4x4 inverse quantization and
Inverse Discrete Cosine Transform (IDCT) as specified in the H.264/AVC
video coding standard

blur_metric  A Matlab script which computes the blur metric for image quality
assessment as described in the work: P. Marziliano, F. Dufaux, S.
Winkler and T. Ebrahimi, "Perceptual blur and ringing metrics:
application to JPEG2000", Signal Processing: Image Communication, vol.
19, no. 2, pp. 163172, February 2004

ringing_metric  A Matlab script which computes the ringing metric for image quality
assessment as described in the work: P. Marziliano, F. Dufaux, S.
Winkler and T. Ebrahimi, "Perceptual blur and ringing metrics:
application to JPEG2000", Signal Processing: Image Communication, vol.
19, no. 2, pp. 163172, February 2004

Ringing impairment addition
 A Matlab script which introduces, over the luminance component, the
ringing impairment as specified in the ITUT document: "Principles of a
reference impairment system for video", Recommendation ITUT P 930,
August 1996

SSIM index computation
 A C++ program which computes the Structural SIMilarity (SSIM) index as
specified in the paper: Z. Wang, A. C. Bovik, H. R. Sheikh, and E. P.
Simoncelli, "Image quality assessment: from error visibility to
structural similarity", IEEE Transactions on Image Processing, vol. 13
no. 4, pp. 600  612, April 2004

compute_GBIM  A Matlab script which computes the Generalized Block Impairment Metric
(GBIM) as proposed in the work: H. R. Wu and M. Yuen, "A generalized
blockedge impairment metric for video coding", IEEE Signal Process.
Lett., vol. 4, no. 11, pp. 317320, Nov. 1997
