Image type: greyscale LUTs, RGB<br />
‣Pseudocolour in greyscale:<br />
8bit and 12bit greyscale images can be visualised in colour:<br />
Use LookUp tables (LUTs): Assigns a range of colour to the grey levels<br />
> Either use LUT button on startup tool bar or switch to LUT tool bar by<br />
pressing on<br />
(Biophotonics edition)<br />
The following tool bar appears:<br />
‣Colour image (RGB):<br />
an overlap of 3 pixels 8bit (24 bit total)<br />
It’s an additive principle of colours:<br />
We can obtain a certain colour by adding 3 primary colours in various<br />
proportions: 256x256x256 = more than 16 million colours.<br />
Different type of colour coding: RGB, CYMK.<br />
RGB: each colour is coded on 1 octet (8bits). Each pixel is a combination of 3<br />
octets (3 x 8 = 24 bits total with Red = 0-255, Green = 0-255, Blue = 0-255.<br />
1 pixel = 3 octets = 24 bits<br />
