Spatial ARMA models and its applications to image filtering

Asymptotic results for spatial causal ARMA models

The paper establishes a functional central limit theorem for the empirical distribution function of a stationary, causal, ARMA process given by Xs,t = i≥0 j≥0 a i,j ξ s−i,t−j , (s, t) ∈ Z 2 , where the ξ i,j are independent and identically distributed, zero mean innovations. By judicious choice of σ−fields and element enumeration, one dimensional martingale arguments are employed to establish t...

Monocular Depth Estimation: Applications to Image Segmentation and Filtering

This Ph.D. dissertation addresses the problem of estimating depth ordering information from single images, a key issue in image understanding that in recent years has focused the interest of the community. Motivation behind this tendency is provided by several important applications that could beneficiate of advances in the field such as automatic object removal, image indexing, 3D scene recons...

Edge Oriented Spatial Image Filtering Technique

Many techniques have been reported earlier in open literature in the area of digital image enhancement. In this paper, a novel approach is presented which improves the accuracy and minimizes the blurring effect with edge preservation. The work involved construction of a new filter using weighted average method, an edge filter and a combiner. The new filter thus constructed has been tested and e...
