Cerebral venous sinus thrombosis (CVST), a rare but deadly disorder, causes papilledema as well as a number of frequent clinical symptoms, including excruciating headaches, focal seizures, and paralysis on one or both sides of the body. In this intriguing case study, we present the clinical narrative of a 45-year-old man who sought medical attention due to severe headaches persisting for two days. Concurrently, he experienced an abrupt onset of tingling and numbness in his left upper arm.

Most state-of-the-art superpixel segmentation methods are unsupervised in nature and thus cannot fully utilize frequently occurring texture patterns or incorporate multiscale context. In this paper, we show that superpixel segmentation can be improved by leveraging the superior modeling power of deep convolutional autoencoders in a fully unsupervised manner.

While many automated methods for segmentation perform very well, few generalize reliably to diverse datasets. Such automated methods could significantly benefit from at least minimal user guidance.
