1. Augmented Reality and 3D modelling Done by Stafford Joemat Supervised by Mr James Connan

2. Project Overview Marker-based Augmented Reality uses a camera and a visual marker to determine the center of orientation and range of its coordinate system The system is effectively a driver that allows users to superimpose a 3D object on a predefined marker, across multiple frames using fixed input video source.

3. Project Overview Object Orientated Analysis  Grayscale  Speed Up Robust Features (SURF)  OpenGL Object Orientated Design User Interface Specification

4. Greyscale Fast image processing due to limited detail. Image intensity is stored in greyscale 8 bits per sampled pixel, which allows 256 different intensities Red, green, and blue (RGB) are primary colours. Gamma expansion is used to get their linear intensity encoding to convert image into approximate level of grey

5. Greyscale

6. Speed Up Robust Features (SURF) Computer vision algorithm used for object recognition SURF is used to create an image pyramid It filters the pyramids appropriately to detect points of interest. By calculating the features it then compare with features of another image to find matches.
