SQL stored procedure

Job ID: 31329309

Budget: $250 – $750 USD

Description
Products are stored in a mysql DB where each product has a colour stored in HEX

The big picture is that we need to do nearest neighbour search in a table to find the closest matching colour to a specific HEX colour.
There are many ways, but we need an experienced coder to do this little job to implement the Delta E or any other better search function in MySQL.

We can for example use Delta E for CIELAB that can be made in SQL (https://stackoverflow.com/questions/31798883/performance-of-delta-e-cie-lab-calculating-and-sorting-in-sql)

Euclidean distance can not be used since the Delta E is considering the perception of the Eye's way of perceiving colours. CIELAB 2000 Delta E considers this too.

If you have done this kind of work in SQL previously and colour search this is the job for you.

Work to do:
1. adjust the code in the URL so it fits our table in a MSQL DB
2. Make Nearest Neighbour Search, NNS (similar to K-NN)

Time:
The time this will take to copy the code in the URL and then adjust it for our needs and make NN searches will take approx 2 days for you to do.
Not much more.
