Image Warping
نویسنده
چکیده
This note introduces the concept of image warping and treats the special case of Euclidean warping along with a discussion of a Matlab implementation. Secondly an application of image warping is given; namely image mosaicing where images are stitched together – e.g. to form a panoramic view. Effort has been put into making the text as self-containing as possible. However, basic knowledge of linear algebra is a requirement. The note is intended for an introductory image analysis course.

Tearable Image Warping for Extreme Image Retargeting
We introduce a new image geometric transformation, named tearable image warping, for content-aware image retargeting and recomposition. In tearable image warping, an object is allowed to partially detached from the background during warping, which allows the background to warp more freely without distorting the object. The part of the object that is still attached to the background ensures that...

متن کاملEnhancement by image-dependent warping
All image warping algorithms to date are image-independent, namely, relate only to the geometry of the image plane, ignoring the content of the image. We show that taking the image content into account yields elaborate warping schemes which may be used to enhance, sharpen and scale images. Sharpening the image is achieved by "squashing" the pixels in edge areas, and "stretching" the pixels in f...
متن کاملImage warping as an image enhancement post-processing tool
A method to improve the results of image enhancement is proposed. The method is based on pixel grid warping, the main idea is moving pixels in the direction of the nearest image edges. Warping allows to make edges sharper while keeping textured areas almost intact. Experimental applications of the proposed method for image enhancement algorithms show the improvement of image quality.
متن کاملSubsurface Domain Image Warping by Horizontal Contraction and its Application to Wave-Equation Migration Velocity Analysis
A kinematically correct choice of velocity focuses subsurface offset image gathers at zero offset. Infinitesimal warping from the current image towards its focus can be approximated by a horizontal contraction. The image residual can be then taken as the difference between the warped and the original image to account for the velocity error. Least squares fitting of the effect of a velocity pert...
