Colour Correction of Edinburgh Central Mosque Model

Nobuyuki Bannai, Alexander Agathos and I developed a method for adjusting the colours on multiple texture maps, so that the resulting 3D models would render with consistent colouring. Nobuyuki then applied this to a model of the Edinburgh Central Mosque. The underlying triangulation was made by hand and then the adjusted texture maps were used. Papers on the topic are cited below.

Before and after correction

Before correction - notice the patchwork aspect

We also explored automatic modelling using a 3D scanner. The data was great (200 million points accurate to several mm). But it had too many outliers (est. 1% = 2 million), which even with successful data cleaning lest too many bad points (est. 0.01% = 20,000).
