Arithmetic operation belongs to one of the elementary transformations of image. The research on quantum image arithmetic operation is of great value for the rapid realization of image color transformation. In this chapter, quantum color image representation based on the HSI color space (QIRHSI) is used as the image representation model of quantum image arithmetic operation. Based on this model, the intensity inversion, complement, addition and subtraction operations are designed.

To achieve a certain desired visual effect, the pixel positions of the input image are mapped to positions different from the original ones so as to change the display effect of the original image. This process is called the geometric transformation of the image. Geometric transformations mainly include geometric correction of the image and spatial transformations (scaling transformation, rotation, and affine transformation) [ 1 – 26 ] . This chapter proposes the geometric transformations of the QIRHSI quantum color image, including basic geometric transformations and scaling operations, and further studies the unitary operators of geometric transformations and the corresponding quantum circuits.
