Binary Classification from a 3x255 array in Python?

[TrickyWitcher]

Relatively new to Python and have no idea where to start. I've been assigned the task of binary classification of values in 3x255 array from a text file. These values are sets of RGB converted from HSV, where H is the only value that changed, while S and V both stay at 100. The resulting output of going through all of the H values make up the array, which is in RGB. Can someone point me in the right direction, or give me some example code? Attached is a header file that contains the output in an array, if it helps.

A few questions:

• How is the text file formatted?
• Are you trying to derive H from RGB -> HSV? (Wording in OP is a little confusing to me)

The text file is likely going to be CSV, though I have no specifics.

 

As for the colours, the values will already be in an array, formatted in RGB. I need to write a binary classifier for those.

To start here, if you don't know file I/O already, I'd suggest looking at https://docs.python.org/3/tutorial/inputoutput.html. If you're not using Python 3.7, a drop-down menu on the top of the page will let you select the version you are using, though I don't think Python 3.x has changed much.

 

CSV makes it easy, since you can remove the characters you don't need using .replace() and then use a .split() to get each item as a list.

not exactly sure what you're asking but, if you need to, you can use the colorsys module to convert between color systems
