Image Morphing

Morphing is also used in the gaming industry to add engaging animation to video games and computer games. However, morphing techniques are not limited only to entertainment purposes. Morphing is a powerful tool that can enhance many multimedia projects such as presentations, education, electronic book illustrations, and computer-based training

Partage de données environnementales pour la découverte et l'observation de la terre

National audienceLe but de cet article est de montrer comment les techniques basés sur l'image et la réalité augmentée (RA) peuvent s'avérer être une aide précieuse à la découverte de la terre et l'observation de l''évolution de l'environnement. Le support de l' étude est tout naturellement le Smartphone qui est devenu en quelques années l'appareil qui nous est le plus familier, qui nous accompagne quotidiennement partout ou nous nous déplaçons

In this paper, a new class of image morphing algorithms is proposed based on the theory of optimal mass transport. The 2 mass moving energy functional is modified by adding an intensity penalizing term, in order to reduce the undesired double exposure effect. It is an intensity-based approach and, thus, is parameter free. The optimal warping function is computed using an iterative gradient descent approach. This proposed morphing method is also extended to doubly connected domains using a harmonic parameterization technique, along with finite-element methods

Improved Mesh_Based Image Morphing ‎

        تحويل الصورة هي عملية متعددة الخطوات تلك التي  تولد سلسلة من الانتقالات بين صورتين. والفكرة هي الحصول على سلسلة من الصور الوسطية التي عند وضعها  جنبا إلى جنب مع الصور الأصلية من شأنه أن يمثل التغيير من صورة واحدة إلى أخرى.  عملية التحول  تتطلب وقت واهتمام بالتفاصيل من أجل الحصول على نتائج جيدة. تحول الصورة يتطلب عمليتين على الأقل هما التشويه والتداخل. التشويه هو عملية التحول الهندسي للصور، في حين  عملية التداخل تمثل  تداخل لون كل بكسل على مر الوقت من  قيمة الصورة الاولى الى ما يقابلها من قيمة الصورة الثانية. تقنيات تحول الصوره تختلف في الاسلوب  عن  اجراء تشويه الصورة. هذا العمل يقدم دراسة  لتقنيات مختلفة لبناء تحول الصور عن طريق استعراض تقنيات تشويه مختلفة. واحد من الاساليب السائده لعملية التشويه هو التشويه الشبكي الذي يعاني من بعض المشاكل بما في ذلك الظلال. هذا العمل المقترح ينفذ لتحسين تقنية التشويه الشبكية لبناء الصور المتحولة. وتبين النتائج أن الأسلوب المقترح يمكنه التغلب على مشاكل تقنية الشبكة التقليديةImage morphing is a multi-step process that generates a sequence of transitions between two images. The thought is to get a ₔgrouping of middle pictures which, when ₔassembled with the first pictures would represent the change from one picture to the other.  The process of morphing requires time and attention to detail in order to get good results. Morphing image requires at least two processes warping and cross dissolve. Warping is the process of geometric transformation of images. The cross dissolve is the process interpolation of color of eachₔ pixel from the first image value to theₔ corresponding second imageₔ value over the time. Image morphing techniques differ from in the approach of image warping procedure. This work presents a survey of different techniques to construct morphing images by review the different warping techniques. One of the predominant approaches of warping process is mesh warping which suffers from some problems including ghosting. This work proposed and implements an improved mesh warping technique to construct morphing images. The results show that the proposed approach can overcome the problems of the traditional mesh techniqu

Facial image morphing by self-organizing feature maps

[[abstract]]We propose a new facial image morphing algorithm based on the Kohonen self-organizing feature map (SOM) algorithm to generate a smooth 2D transformation that reflects anchor point correspondences. Using only a 2D face image and a small number of anchor points, we show that the proposed morphing algorithm provides a powerful mechanism for processing facial expressions.[[conferencetype]]國際[[conferencedate]]19990710~19990716[[booktype]]紙本[[iscallforpapers]]Y[[conferencelocation]]Washington, DC, US

A Survey of Morphing Techniques

Image morphing provides the tool to generate the flexible and powerful visual effect. Morphing depicts the transformation of one image into another image. The process of image morphing starts with the feature specification phase and then proceeds to warp generation phase, followed by the transition control phase. This paper surveys the various techniques available for all three stages of image morphing

Two-scale shape optimisation based on numerical homogenisation techniques and variational sensitivity analysis

This contribution presents a theoretical and computational framework for two-scale shape optimisation of nonlinear elastic structures. Particularly, minimum compliance optimisation problems with composite (matrix-inclusion) microstructures subjected to static loads and volume-type design constraints are focused. A homogenisation-based FE2 scheme is extended by an enhanced formulation of variational (shape) sensitivity analysis based on Noll’s intrinsic, frame-free formulation of continuum mechanics. The obtained overall two-scale sensitivity information couples shape variations across micro- and macroscopic scales. A numerical example demonstrates the capabilities of the proposed variational sensitivity analysis and the (shape) optimisation framework. The investigations involve a mesh morphing scheme for the design parametrisation at both macro- and microscopic scales
