Transforming an image

Image transformation involves the translation, rotation, magnification, or shear of an image. If (x,y) is the coordinate of the pixel of an image, then the transformed image coordinate (u,v) of the new pixel can be represented as follows:

• Translation: Some examples of translation constant values are c11 = 1, c12 = 0, and c13 = 10; c21 = 0, c22 = 1, and c23 = 10. The resulting equation becomes u = x + 10 and v = y + 10:

• Rotation: Some examples of rotation constant values are c11 = 1, c12 =0.5, and c13 = 0; c21 = -0.5, ...
