Comparison of Computer Vision and Photogrammetric Approaches for Epipolar Resampling of Image Sequence
Epipolar resampling is the procedure of eliminating vertical disparity between stereo images. Due to its importance, many methods have been developed in the computer vision and photogrammetry field. However, we argue that epipolar resampling of image sequences, instead of a single pair, has not been studied thoroughly. In this paper, we compare epipolar resampling methods developed in both fiel...
متن کاملA Fast Image Resampling Method
This paper proposed a fast resampling method for digital image. Recently, using mobile device is very popular. It is very important to make the images suitable for every different mobile device. There are many methods to change the size of image. The most important methods are image resampling and image retargeting. This paper proposed a fast resampling method. The method is suitable for mobile...
متن کاملContourlet-Based Edge Extraction for Image Registration
Image registration is a crucial step in most image processing tasks for which the final result is achieved from a combination of various resources. In general, the majority of registration methods consist of the following four steps: feature extraction, feature matching, transform modeling, and finally image resampling. As the accuracy of a registration process is highly dependent to the fe...
متن کاملRobust Resampling Detection in Digital Images
To create convincing forged images, manipulated images or parts of them are usually exposed to some geometric operations which require a resampling step. Therefore, detecting traces of resampling became an important approach in the field of image forensics. In this paper, we revisit existing techniques for resampling detection and design some targeted attacks in order to assess their reliabilit...
متن کاملInvestigation of Resampling Effects on Irs-1d Pan Data
Image resampling is frequently employed in geometric correction as a part of preprocessing of a remotely sensed image. The resampled images will have a noticeable change in image quality, which may have an adverse impact on the accuracy of subsequent image analysis for information extraction. Information of edges is very important, especially in high spatial resolution imagery. The present stud...
متن کاملA Fast Beef Marbling Segmentation Algorithm Based on Image Resampling
With the miniaturization and portability of online detection and grading equipment, traditional PC is being replaced with ARM or DSP embedded systems in beef quality grading industry. As the low basic frequency of embedded system, the traditional beef marbling segmentation method can not meet requirements of real-time performance. The fast segmentation algorithm of beef marbling based on image ...
