Long-term persistent tracking in ever-changing environments is a challenging task, which often requires addressing difficult object appearance update problems. To solve them, most top-performing methods rely on online learning-based algorithms. Unfortunately, one inherent problem of online learning-based trackers is drift, a gradual adaptation of the… (More)
This paper presents improved bounds for the norms of exceptional finite places of the group K 2 O F , where F is an imaginary quadratic field of class number 2 or 3. As an application we show that K 2 Z[ √ −10] = 1.
