As panoramic images are widely used in many applications, efficient image stitching methods that provide visually pleasant image mosaics are needed. In this paper we discuss a novel concept for smart camera image stitching based on graph pyramids. For a multi-camera system, the images have to be aligned accordingly to create an image mosaic. Instead of calculating the corresponding transformati...

In electron microscopy, a large field of view is commonly captured by taking several images of a sample region and then by stitching these images together. Non-linear lens distortions induced by the electromagnetic lenses of the microscope render a seamless stitching with linear transformations impossible. This problem is aggravated by large CCD cameras, as they are commonly in use nowadays. We...

“Imaging signs” are a critical part of radiology’s language. They not only are important for conveying diagnosis, but may also aid in indexing radiology literature and retrieving relevant cases and images. Here we report our work towards representing and categorizing imaging signs of abdominal abnormalities in figures in the radiology literature. Given a region-of-interest (ROI) from a figure, ...

The general problem of mosaicing is to create a single seamless image by aligning a series of spatially overlapped images. The result is an image with a field of view greater than that of a single image. Traditionally this research has been aimed at stitching together images taken by aerial or satellite reconnaissance equipment. With the advancement of personal computing equipment, the creation...

Image stitching or mosaicing is a challenging vision problem, especially when considering aspects like high definition content, real-time, and proper compensation of the parallax error of objects at different distances to the camera system. Today many approaches to image stitching exist, most of them deal with medium resolution images, offline processing, or are restricted to objects at similar...

We present an interactive program called HistoStitcher(©) for accurate and rapid reassembly of histology fragments into a pseudo-whole digitized histological section. HistoStitcher(©) provides both an intuitive graphical interface to assist the operator in performing the stitch of adjacent histology fragments by selecting pairs of anatomical landmarks, and a set of computational routines for de...

In China, efforts are being made to preserve historical documents in the form of digital data so that they can be effectively used while being protected. Stitching technology is expected to play a role in these efforts as it can be used to divide a large historical document into multiple areas, scan those areas using a compact contactless scanner, and seamlessly connect the resulting images. Si...

Telemedicine has been developed to allow practitioners to remotely connect with patients and with other medical staff. We propose a new system (hardware and software), named DICODERM (COllaborative DIagnosis of DERMatosis), which makes it possible to monitor the evolution of scars after the excision of a tumorous dermatosis (like melanoma). The hardware part of this system is composed of a new ...
