Adaptive rood pattern search for fast block-matching motion estimation
In this paper, we propose a novel and simple fast block-matching algorithm (BMA), called adaptive rood pattern search (ARPS), which consists of two sequential search stages: 1) ini...

Tracking nonparameterized object contours in video
We propose a new method for contour tracking in video. The inverted distance transform of the edge map is used as an edge indicator function for contour detection. Using the concep...

Optimal edge-based shape detection
Abstract--We propose an approach to accurately detecting twodimensional (2-D) shapes. The cross section of the shape boundary is modeled as a step function. We first derive a one-d...

Image compression with adaptive local cosines: a comparative study
Abstract--The goal of this work is twofold. First, we demonstrate that an advantage can be gained by using local cosine bases over wavelets to encode images that contain periodic t...

Tree-structured method for LUT inverse halftoning and for image halftoning
1 Recently the authors proposed a Look Up Table (LUT) based method for inverse halftoning of images. The LUT for inverse halftoning is obtained from the histogram gathered from a f...

Lossy to lossless object-based coding of 3-D MRI data
Abstract--We propose a fully three-dimensional (3-D) object-based coding system exploiting the diagnostic relevance of the different regions of the volumetric data for rate allocat...

Disocclusion: a variational approach using level lines
Object recognition, robot vision, image and film restoration may require the ability to perform disocclusion. We call disocclusion the recovery of occluded areas in a digital image...

Denoising and copy attacks resilient watermarking by exploiting prior knowledge at detector
Watermarkingwith both obliviousdetection and high robustness capabilities is still a challenging problem. The existing methods are either robust or oblivious, but it is di cult to...
