Popis: This paper presents an intelligent control loop add-on to reduce the total amount of hardware operations - and therefore the resulting execution speed - of a real-time depth scanning algorithm. The analysis module of the control loop predicts redundant brute-force operations, and dynamically adjusts the input parameters of the algorithm, to avoid scanning in a space that lacks the presence of objects. Therefore, this approach reduces the algorithmic complexity in proportion with the amount of void within the scanned volume, while remaining fully compliant with stream-centric paradigms such as CUDA and Brook+.
