An Image Registration Developer creates algorithms and software to align different images of the same scene. They ensure the spatial correspondence between images taken at different times, from different viewpoints, or by different sensors. Their work is essential in fields like medical imaging, where they align images from different modalities (MRI, CT, ultrasound), or satellite imagery, where they align aerial photos with different resolutions or angles. They need strong skills in image processing, computer vision, and sometimes machine learning. They also need to understand the physics of the imaging process to build models for geometric and photometric distortions.
