Abstract
We present a new method for image deformation. The warping technique provides smooth distortion with intuitive and easy manipulation. Driven by a restrained force field, the input image is deformed gradually and continuously. The method allows us to customize the force fields and the region of interest manually through some simple steps. Experimental results demonstrate the effectiveness and convenience of the approach.
Highlights
Image deformation has proven to be a powerful tool for image editing
In the last two decades, a considerable amount of research has been directed towards image deformation
The classical method for image deformation is obtained by linear combination of affine transformations; see [1] [2]
Summary
Image deformation has proven to be a powerful tool for image editing. There are many applications from animation, morphing, to image correction and recognition. Free-form deformation methods (see [5]) and skeleton-based techniques (see [6]) distort the shapes by manipulating the space in which they are embedded. They are very efficient in computation and easier to be implemented, but they have not enough in providing convenient or intuitive tools for the user. The typical PDE-based approaches deform a given image with a specially-designed PDE, and obtain the desired result as the solution of this PDE with the input image as initial conditions. Unlike the classical PDE-based filtering models, we attempt the useful tool to evolve an image on the coordinates or displacement, not on the value of intensity or the vector of color
