change in size for the similarity transformation but the size remains the same for rigid transformation.
Step-by-step explanation:
Rigid transformation ensures the size and shape remains the same after their transformation.
Rigid transformation includes rotation, reflection and translation.
In Similarity transformation, the shape remains the same but the size doesnot. There is a rescaling of the original image.
It is either enlarged or reduced.
This transformation occurs in dilation.
As a result, the original and new image become similar shapes. The shape are the same but the size differs.
Hence, the major difference lies in the change in size for the similarity transformation but the size remains the same for rigid transformation. The shape reamains unchanged in both transformations.
