Witch vision algorithm dose Pixy used in the great marketing video?

It detects the coloured object or the shape of the object?I read the code but dose not know much about the “LUT” algorithm.

Hi Tiger,

Pixy does not currently detect any shape features of the objects, only color (which is based on the hue). The LUT is a Look-Up Table (LUT), which is essentially a data structure that tells us what colors are included in each signature/model you generate. Given a color, you can query this data structure and it will tell you in constant time if the color is included in the signature/model or not. This is partially why Pixy is so fast - we were able to find the right data structure and algorithms to ensure real-time processing.

I’m having a hard time finding a good resource on color lookup tables (CLUTs), so for now I’ll have to refer you to the “Wikipedia article”:http://en.wikipedia.org/wiki/Colour_look-up_table.

Hope this helps.

Thank you for reply.
I like Pixy very much.I want to use Pixy as my first color detect kit.As Pixy is a open source project,I think it is very useful for students.I want to do some more vision algorithm in this project.But I can not understand the source code of Pixy.How can I solve this problem?
