Adaptive Skinny Smudge Tool

Abstract

This paper is related to an adaptive skinny smudge tool deciding a radius of the master adaptively as well as using an arbitrary master shape. The smudge tool should seem familiar to finger paintings in kindergarten. We can use the smudge tool by selecting its icon on the toolbox of Adobe Photoshop CS6 and dragging in the direction you want to smudge while holding the mouse button down on the image. As the smudge tool blends all the pixels within a fixed radius of the master to generate the result image, its disadvantages are to smudge even the pixels in the undesired region, and to often vary the radius of the master manually. In this paper to reduce the disadvantages, an adaptive skinny smudge tool is proposed. The proposed adaptive skinny smudge tool not only uses the arbitrary master shape adhered closely to the contour shape, but also is able to decide adaptively the radius of the master according to the characteristics of the pixel distribution. Thus, the proposed skinny smudge tool has the advantage of automatically varying the radius of the master and applying the smudge effect to the desired region regardless of the background.
