C project HEVC software

Inter Prediction

This project focuses on TZ Search algorithm, i.e. the fast ME algorithm implemented in

HM reference software. TZS consists of three main stages: Initial Grid Search, Raster

Scan and Refinement. In [1] authors propose a fast ME algorithm based on TZS, where

the first step remains as is, whereas the next two are replaced by the algorithms presented.

In[2] authors mainly focus on limiting the ME’s search area. They propose an algorithm

that adaptively set the search area, according to CTUs depth. Furthermore, apart from

the search pattern used by TZS in its first step, they propose some other alternatives.

Students, through this project are asked to merge the basic ideas presented in the above

works. More precisely they are asked to implement the adaptive search area presented in

[2]. Moreover, there are asked to modify TZS as follows:

– Add to first step i.e. Initial Grid Search one of the following search patterns (Hexagon,

Pentagon or Triangle) presented in [2]

– Replace the other two steps with one of the algorithms presented in [1]

Implementation & Testing

The algorithms should be implemented in HEVC reference software. To verify your output

you should decode the bitstream produced by the encoder with the HM decoder (pls. see the

Software-manual). Results (such as time, bitrate, PSNR) are shown as summary in the terminal

(where the program runs). It would be helpful to compare some (or all) of these results with

the ones presented in the papers.

As experiments with HM are time consuming it is suggested that you run experiments for 100

frames, QP 32, using the LowDelay (P frames only) configuration. The sequences that should

be used for the experiments are:

• for inter prediction project

– RaceHorses.

– PartyScene.


The deliverable of the project will consist of a folder containing:

• a folder with the source code

• a final report

The final report of the project will be in the form of a scientific paper. The report should be

written in English with a maximum page limit of five (5) printed pages (10-point font) including figures and a minimum of (3) three. Please use the standard IEEE conference templates.

Indicatively, the report should have the following Sections (with the formatted indicated by the

aforementioned template)

I. Introduction

II. Overview of TZ Search (with reference to search area) or Overview of Intra Prediction in


III. Algorithm

IV. Experiments

V. Conclusions
