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.10.1111/1467-8659.1350285285-292
