The geometric transformation of an image with irregular shapes from a source space to a target space requires a huge number of multiplications and additions for each pixel. Such a through put is impossible to deliver by any processor in real‐time. This paper presents a new transformation matrix which can be used toper form real‐time 2‐D geometric transformations economically. The implementation of the transformation engine that is used to execute the transformation matrix is also presented. Experimental results indicate that real‐time geometric transformations based on a 4 × 4 transformation mesh can be achieved with the use of the transformation engine. This real‐time transformation function is useful in warping and blending of images, and can be easily extended to perform irregular shape transformations with a large number of control points in the transformation mesh.
