Sažetak
This paper presents two solutions for detection and localization of spherical markers in photographs. The proposed solutions enable precise detection and localization in sub millimeter range. High precision localization is required for brain surgery, and presented research effort is part of a project of developing and deploying a robotic system for neurosurgical applications. Two algorithms for Hough transform using several edge detection algorithms are proposed, and their results compared and analyzed. Results are obtained for both NIR and visible spectrum images, and required high precision is achieved in both domains.
