Research On Panoramic Image Mosaic Method Based On Camera Calibration, Jialin Ma, Jinming Zhang, Weixin Sun

Journal of System Simulation

Abstract: A panoramic mosaic method was proposed based on camera calibration, geometric distortion correction and rotation transformation processing was done for stitching image, in order to improve the accuracy of image registration and panorama stitching quality. The homography was acquired by calculating the camera linear calibration, and the inside and outside parameters of the homography were separated. The radial distortion of the image was calculated by the inside parameters, and the image geometric distortion was corrected; a sequence of images was transformed in the same world coordinates using the external parameters; image registration was achieved accurately though the same name …

Applications Of Image Processing Techniques And Spatial Data Analytics For Pressure Mapping Analysis, Joan Yamil Martinez

Dissertations

The technological advancements in sensors, monitoring systems, and tracking devices are changing how we study our environment; big data sets are becoming more and more prevalent due to the increase of information gathered with ease. One system benefiting from these technological improvements is pressure mapping technology, an easy-to-use and cost-effective solution for assessing contact pressure distributions.

Pressure mapping systems generally produce data sets of very large volume, especially when used for continuous tracking and monitoring, and are widely used for research in fields of ergonomics, sports, industries, and health disciplines. Pressure mapping systems are particularly important in the study of …

Overview Of Image Segmentation And Registration For Spine Biological Modeling, Juping Gu, Tianyu Cheng, Hua Liang, Jianping Wang, Zhao Jian, Cao Yong

Journal of System Simulation

Abstract: The prevalence of common spinal fractures is high in this day. Spinal image segmentation and registration are the key step and prerequisite of target recognition, biomechanical modeling and finite element analysis. They are also the key technology of noninvasive surgery navigation. Aiming at the problems of spinal image processing, the classical medical image segmentation and registration algorithm is introduced. It also analyzes the defects and prospects of the future development trend of spine image processing. The research results have certain significance for further understanding of spinal medical image processing and promoting the development of rehabilitation therapy for spinal fractures.
