Image Translation and Rotation

To adjust images or rotate them for graphics designing and other purposes, we can use photo editing applications to edit them. However, if we have thousands of images to edit, it’ll take hours to edit them all. The OpenCV library provides image translation and rotation to solve this problem.

Create a translation matrix

To create a translation matrix, we use the float32() method of the NumPy library. We use the following code to create a translation matrix:

translationMatrix = np.float32([[1, 0, x], [0, 1, y]])

Note: We need to import np first, which is the NumPy library.

Here, x and y are the important variables that determine the magnitude and direction of the translation of the image.
