Fig. 4From: Image processing for optical mappingTiling. Example of tiling three images from a microchannel. A horizontal span of about 140 microns is covered by each image. The blue outlines represent the image borders. The estimated tiling transformation provides the translation of frames to achieve this seamless mosaic, but the mosaic itself is not explicitly constructed. Estimating the tiling transformation is required to extract multi-frame RmapsBack to article page
