y_table and c_table transposes?

[siegelaaron94]

How confident are you that the transposes on the y_table and c_table are correct? To me, they don't seem correct, and depending on the quality level you can get the average error between the output and OpenCV's result by not transposing them.

The transpose is there so the linear algebra works out correctly when converting a whole image instead of a single color value [R G B], see:

skimage does the same thing:

(I didn't know this, I was worried by the same thing and had to look it up)

The program's output is different from OpenCV's. Is there any way to fix it?🙏
