In this paper, we propose a new method to compensate for lens distortions in image stitching. Lens distortions that arise from the nonlinearity of a lens are the main cause for mismatches in stitching images. We estimate the distortion factors for each image using the Division Model and linearize the projected relationships between matching distorted feature points. Because our method works at ...

OBJECTIVES Content-based access (CBA) to medical image archives, i.e. data retrieval by means of image-based numerical features computed automatically, has capabilities to improve diagnostics, research and education. In this study, the applicability of CBA methods in dentomaxillofacial radiology is evaluated. METHODS Recent research has discovered numerical features that were successfully app...

Traditional feature-based image stitching technologies rely heavily on feature detection quality, often failing to stitch images with few features or low resolution. The learning-based solutions are rarely studied due the lack of labeled data, making supervised methods unreliable. To address above limitations, we propose an unsupervised deep framework consisting two stages: coarse alignment and...

The panorama is more effective image-based rendering one of the methods. Papers on the panorama generation process, and key technologies on one of the most panoramic picture of the stitching algorithm is classified, summarize and compare.

Clear and wide-angle images are essential to detect and trace objects for applications such as CCTV and unmanned vehicles. Fog, haze, and rain causes problem in getting clear image and lowers the detection rate of objects. To remove haze, we use median dark channel prior which can reduce the complexity of hardware. Image stitching stitches a number of images from multiple cameras into single wi...

Planar-mirror-based catadioptric method is one of the most hot topics in recent years. To overcome the disadvantages of the planar-mirror-based catadioptric panoramic camera, described by Nalwa (1996, 2001, 2000), such as the requirement for high-precision optical device designing and the stitching lines in the resulting images, we proposed a planar-mirror-based video image mosaic system with h...

This paper proposes an algorithm which automatically aligns and stitches the component medical images (fluoroscopic) with varying degrees of overlap into a single composite image. The alignment method is based on similarity measure between the component images. As applied here the technique is intensity based rather than feature based. It works well in domains where feature based methods have d...
