Maze solving algorithm is used to find the shortest path between the source and target point in a given labyrinth. In this paper, an improved algorithm based on existing mathematical model inspired by an amoeboid organism, Physarum polycephalum, is proposed to solve maze solving problems. The positive feedback mechanism in the mathematical model is adopted in our algorithm. Meanwhile, some fuzzy rules...
We consider multi-hop decode-and-forward relaying OFDM systems in this paper. All the relay nodes are assumed to be regenerative and working in half-duplex mode. We propose adaptive power allocation (PA) algorithms to maximize the overall system capacity and minimize the system outage probability, respectively. Simulation results show that the proposed algorithms outperform the existing PA algorithms...
Most existing global contrast enhancement algorithm can not deal with high dynamic range images. Thus a simplified logarithmic transformation equation has been proposed in this paper. A partially overlapped sub-block method is also adopted to perform local contrast enhancement. For purpose of optimization, two contrast measures are used for finding optimal transformation parameters. They merge into...
Corners in images represent a lot of important information. Extracting corners accurately is significant to image processing, which can reduce much of the calculations. In this paper, two widely used corner detection algorithms, SUSAN and Harris corner detection algorithms which are both based on intensity, were compared in stability, noise immunity and complexity quantificationally via stability...
