Simultaneous Localization and Mapping (SLAM) Autonomous Driving are becoming increasingly more important in recent years. Point cloud-based large scale place recognition is the spine of them.

Cerebral venous sinus thrombosis is an uncommon cause of stroke presenting with varied presentation patterns. We report a case of a 21-year-old woman with superior sagittal sinus (SSS) thrombosis (SSST) developing after childbirth, presenting with visual hallucinations, severe headache, and tonic-clonic seizures. Time-of-flight magnetic resonance angiography (TOFMRA) demonstrated the presence o...
