Finding an optimum function is not only a theoretical mathematical problem but also a particular engineering problem. Many aspects in the electrical and electronics field (by example: image processing, filter matching, optimization of network parameters, resources allocation) can be solved by finding a target function and his minimum or maximum. For such problems, usually an analytical solution is...
We report a two-dimensional (2D) pixel block scanning architecture for image segmentation by segment growing. This architecture can optimize processing speed, power consumption, and circuit area by modifying size and shape of the pixel block. Real-time processing can be maintained by using additional the two important techniques of (i) boundary-scan of the grown segment only, (ii) continued block-internal...
An optimized architecture is proposed for real-time automatic cloud detection system with Spectrum and Texture Analysis Combination (STAC) approach. The STAC approach is hard to be implemented in hardware, for the calculation of fractal dimension (FD) and angle second moments (ASM) of the approach consumes large computation time and hardware resources. By optimizing the calculation process of the...
In this paper, we propose a hardware implementation of a Feed-Back Chaotic Synchronization (FCS) for designing a real-time secure symmetric encryption scheme. This proposed scheme allows for the design and implementation of real time synchronization between two embedded chaotic generators for secure communications. The implementation and experimental results mapped on two Xilinx FPGA Virtex technology...
