Image Arithmetic Transforms

Arithmetic transform changes the values of image pixel and is applied point to point.

Types of Arithmetic Transforms

  1. add()

  2. addWeighted()

  3. subtract()

  4. multiply()

  5. divide()

  6. absdiff()

  7. bitwise_and()

  8. bitwise_or()

  9. bitwise_xor()

  10. bitwise_not()

  11. sqrt()

  12. pow()

  13. abs()

  14. cuberoot()

  15. exp()

  16. log()

Image Geometrical transforms

Geometrical transforms change the position of the pixel and not the value. Hence after such transforms the position of the pixel changes to a new position.

The examples of geometric transform is

  1. Scaling
  2. Cropping
  3. Wrap perspective
