WitrynaI read that a translation matrix would typically be [1 0 tx; 0 1 ty; 0 0 1] where (tx, ty) would be the new spatial co-ordinates that the image would move to,and you would multiply the translation matrix by the C = imread (image), however how would that work if the size of the image was for example 684 X 1024 ? I tried to do it this way instead.

Witryna4 lut 2015 · A transformation matrix allows to alter the default coordinate system and map the original coordinates (x, y) to this new coordinate system: (x', y'). Depending on how we alter the coordinate system we effectively rotate, scale, move (translate) or shear the object this way. A transformation matrix is a 3-by-3 matrix: Witryna12 sty 2024 · Now that we have defined our translation matrix, the main translation takes place on line 24, where we call the cv2.warpAffine function. Within this function, we need to provide 3 parameters.
