Project Overview

The main purpose of system is to track an object across multiple frames using fixed input source.

Introduction

Interface User Interface Specification

Components Portable Pixel map (PPM) Grayscale Background Subtraction Skin Detection

High Level & Low Level Design

PPM is a type of image file format. Each pixel can be easily manipulated since it

is in an understandable format.

Portable Pixelmap (PPM)

Red

Green

Blue

Every colour image a pixel consists of 3 values; red, green and blue.

A Grayscale image value of each pixel is the same.

To convert pixel colour to its appropriate level of grey, the following calculation is needed.

Red X 30% Green X 59% Blue X 11% Greyscale

This is used to identify whether a set of pixels is a potential skin area.

Convert from RGB to HSV colour space.

The threshold values is used to distinguish between skin and non skin pixels.

Skin colour detection

The skin colour detection will be used to identify whether a person has been detected in a video.

Object Orientated Approach

Interface

Term 3 Implement Skin detection. Extend functionality on interface Display tracked object in video. Testing for correctness.

Term 4 Testing and evaluating software Create User Manual.
