Region-based image registration for mosaicking
International Journal of Computer Applications in Technology, 2010In this paper, a method for image registration using 2D regions as correspondence features is proposed. The proposed method consists of three stages. First, a region segmentation technique is used to find reasonably good regions in image pairs. Second, an adjacency relationship based region matching technique is proposed to find corresponding regions ...

Automatic registration and mosaicking of conservation images
SPIE Proceedings, 2013As high-resolution conservation images, acquired using various imaging modalities, become more widely available, it is increasingly important to achieve accurate registration between the images. Accurate registration allows information unavailable in any one image to be compiled from several images and then used to provide a better understanding of ...

A workflow approach for mosaicking UAV images
2016 Fifth International Conference on Agro-Geoinformatics (Agro-Geoinformatics), 2016In recent years, the Unmanned Aerial Vehicles (UAVs) technologies are widely employed in many fields such as disaster monitoring, map revision, and aerial imagery. A UAV aerial remote sensing system has several advantages such as low cost, high spatial resolution, and flexibility.

Underwater image mosaicking and visual odometry
SPIE Proceedings, 2017This paper summarizes the results of studies in underwater odometery using a video camera for estimating the velocity of an unmanned underwater vehicle (UUV). Underwater vehicles are usually equipped with sonar and Inertial Measurement Unit (IMU) - an integrated sensor package that combines multiple accelerometers and gyros to produce a three ...

Registration and mosaicking of cloud contaminated images
SPIE Proceedings, 2007We propose a new method for image mosaicking. In the first stage, two images are registrated. In the second stage, two images are mosiacked and the intensities of the overlapped area are blended seamlessly. For image registration, our automatic registration method is conducted by defining an energy functional and solving the energy minimization ...

Seamline Determination Based on Segmentation for Urban Image Mosaicking
IEEE Geoscience and Remote Sensing Letters, 2014This letter presents a method of seamline determination based on segmentation for orthoimage mosaicking in an urban area. Image segmentation is used to achieve regions of objects. First, preferred regions through which seamlines are inclined to be passed are determined by spans of segmented regions. Second, pixel-level optimization is carried out using

Image Mosaicking with Optimized Matching of Global and Local Contents
TENCON 2006 - 2006 IEEE Region 10 Conference, 2006Photometric inconsistency and geometric misalignment are the main problems of image mosaicking. In our previous studies, we have introduced a method called curvature-domain image stitching, which can successfully reduce the artifacts caused by these two problems. However, it would be computationally heavy if the whole mosaic region uses this method. In

Contour-based image mosaicking in the presence of moving objects
SPIE Proceedings, 2005Most of previous image mosaicking techniques deal with stationary images that do not contain moving objects. But these moving objects cause serious errors on global motion estimation which is the core process of the image mosaicking since the global motion is estimated biased by local motions due to moving objects. There are some proposed techniques to

Image Mosaicking Through Macro-Feature Affine Matching
2005 IEEE 7th Workshop on Multimedia Signal Processing, 2005This paper presents a new method for registering images related by 2-D affine transformations. The method is based on extracting macro-features from the images to register and matching the polar curves associated with their energies, defined as the squared Fourier transform magnitudes.

A methodology of UAV route planning for fast image mosaicking
2015 23rd International Conference on Geoinformatics, 2015Losses caused by various disasters are continuing to rise as the global disasters frequently occur in recent years. In order to reduce the losses, UAV (unmanned aerial vehicle) technologies are increasingly employed in the emergency management field. Rapid emergency response has a strong demand for fast UAV image processing, while image mosaicking is ...
