A new approach to eye-in-hand image-based visual servoing based on fuzzy modeling and control is proposed in this paper. Fuzzy modeling is applied to obtain an inverse model of the mapping between image features errors and joints velocities, avoiding the necessity of inverting the Jacobian. An inverse model is identified for each trajectory using measurements data of a robotic manipulator, and ...

A video segmentation scheme using stabilized inverse diffusion equations is proposed. The scheme is based on the non-linear scale-space analysis of video lattice. Non-linear diffusion and especially Stabilized inverse diffusion is a very robust method for image segmentation. In this paper the two-dimensional diffusion process has been extended to three dimensions. The segmentation scheme is bas...

My primary research focus is on inverse problems in imaging with applications to science and industry. More broadly, I apply mathematical techniques to model, simulate, and analyze physical and biological systems. Currently, I have active research projects in de-noising of remote sensing images, in image formation for computational photography, and in fast multipole methods for molecular dynami...

A large flexible beam with a tip mass-pendulum system has been proven to be effective vibration-absorbing device for large flexible structures with tip appendages. In this study, the technique of digital image processing is used to demonstrate how unique experimental results can be obtained by the use of high performance data acquisition and high speed cameras. The measurements include time his...

This paper presents an efficient inverse warping algorithm for generating novel views by combining multiple reference images taken from different viewpoints. The method proceeds in three steps. Firstly, the reference images are preprocessed for extracling edge pixels. Secondly, an inverse warping is performed to render the desired image from one primary reference image. By taking advantages of ...

Image alignment is one of the most widely used techniques in computer vision. Applications range from optical flow and tracking to layered motion, mosaic-ing, and face coding. Of particular concern in many applications is the efficiency of the algorithm. This concern has led to the development of several efficient algorithms such as the Hager-Belhumeur algorithm and the inverse compositional al...

The 9/7 wavelet is used for a wide variety of image compression tasks. Recent research, however, has established a methodology for using evolutionary computation to evolve wavelet and scaling numbers describing transforms that outperform the 9/7 under lossy conditions, such as those brought about by quantization or thresholding. This paper describes an investigation into which of three possible...

We describe a closed-form technique for mapping the output of a trained backpropagation network int.o input activity space. The mapping is an inverse mapping in the sense that, when the image of the mapping in input activity space is propagat.ed forward through the normal network dynamics, it reproduces the output used to generate that image. When more than one such inverse mappings exist, our ...

The development of computational algorithms for solving inverse problems is, and has been, a primary focus of the inverse problems community. Less studied, but of increased interest, is uncertainty quantification for solutions of inverse problems obtained using computational methods. In this paper, we present a method of uncertainty quantification for linear inverse problems with nonnegativity ...
