The growth of automatic layout capabilities for publications such as photo books and image sharing websites enables consumers to create personalized presentations without much experience or the use of professional page design software. Automated color correction of images has been well studied over the years, but the methodology for determining how to correct images has almost exclusively consi...

  Introduction: There are several technical features that make PET an ideal device for the noninvasive evaluation of cardiac physiology. Organ motion due to respiration is a major challenge in diagnostic imaging, especially in cardiac PET imaging. These motions reduce image quality by spreading the radiotracer activity over an increased volume, distorting apparent les...

We study the challenging problem of registering images of a non-rigid surface by estimating a Radial Basis Mapping from feature matches. We cast the problem as a Maximum Likelihood Estimation coupled with nested model selection. We propose an algorithm based on dynamically inserting centres and refining the transformation parameters under the control of a selection model criterion. We validate ...

This paper presents a system for refining the accuracy and realism of coarse piecewise planar models from an uncalibrated sequence of images. First, dense depth maps are estimated by aligning a planar region of a scene in each image, approximating camera calibration, and generating dense planar parallax. These depth maps are then robustly fused to obtain incrementally refined surface estimates....

in the recent years, human activities have led to changes in land use and land cover, consequently, these changes lead to the structure and function of ecosystems. spatial-temporal change detection of land use is important to understand the relationships and interactions between human and natural resources and to make appropriate decisions due to changes in land use and land cover occurs in bro...

The Autonomous Exploration for Gathering Increased Science (AEGIS) system enables automated science data collection by a planetary rover. AEGIS analyzes rover images onboard to detect pre-defined science features of interest, enabling targeted instrument data to be acquired immediately with no delays for ground communication. AEGIS analyses images to detect candidate targets and then selects sp...

The sustainable development and utilization of sandy areas in arid semiarid regions is strategic importance to ensure both food ecological security. unique geographical environment these uncontrolled exploitation by farmers lead large amounts fragmented cropland. Despite government management, the quantity distribution croplands unknown, accurate identification region’s can provide data support...

While the pages of a book or thick document to be scanned, two types of geometric and optical destruction for the scanned images arise. As a result of the damages, hick curvy lines of text in the document find and book binding are shaded. This problem makes it difficult to read. In the near future, it is an attempt to correct such images. In this paper, we review the methods for correcting the ...
