LUT get index from .txt file
Hello, beginner here. In class we're currently working with OpenCV for image manipulation.
We're asked to create a
LookUpTable as a .txt file and and change the color of some pixels in an image.
the .txt file is something like this:
I know that I can use a Scanner to read the values etc. but let's assume i just want the value 255 from col3 row3. Is there a direct way to access that value or do it have to loop through each line/value until i get to that point?
I tried using FileReader and BufferReader but I haven't found way to read a specific value.
My inital idea was it to read every value in the LUT and create an array so i don't have to loop through the whole table to get a single entry but that kind of destroys the purpose of a LUT.
TL;DR is there a way to call a specific index from the LUT using only a .txt file?2 Replies
