In our annotation output, the x and y coordinates are normalised to ensure consistency across different image sizes. Normalisation is crucial for accurately representing object positions relative to the image dimensions.

X and Y Coordinates:

• X Coordinate:

  • Normalised x coordinates ($Xnorm​$) are calculated using the formula: $Xnorm = Xraw / Image Width$

  • The result ranges from 0.0 to 1.0, where 0.0(Origin) corresponds to the leftmost edge of the image, and 1.0 corresponds to the rightmost edge.

• Y Coordinate:

  • Normalised y coordinates ($Ynorm​$) are calculated using the formula: $Ynorm = Yraw / Image Height$

  • The result ranges from 0.0 to 1.0, where 0.0(Origin) corresponds to the topmost edge of the image, and 1.0 corresponds to the bottommost edge.
