Mosaicing of endoscopic images
Endoscopic image analysis. Image mosaicing

Image mosaicing is generally performed in several stages. The aim of the first mosaicking stage is to find the location of the pixels in each image of a video sequence within the mosaic frame. In the resulting map, there are usually alignment errors perceptible through texture discontinuities. An additional step is therefore aimed at slightly modifying the position of pixels in the map simultaneously, in order to correct alignment errors. The images of a video sequence are acquired from highly variable viewpoints which, in the field of endoscopy,...
