The evaluation of image noise reduction filter implementation with the Blackfin microcomputer
Stefan Andrei, Sorin Zoican · 2010
This paper evaluates the possibility of the real time implementation of the median-based filter used for noise reduction from images. The filter involves two procedures: an impulse detection algorithm and the noise filtering. Both the impulse detection and the noise filtering procedures are applied through several iterations for better performance. The real time implementation is based on the Blackfin digital signal microcomputer from Analog Devices. The paper is organized as follows: a brief description of the filtering algorithm, the micro signal architecture (MSA), the proposed approach for real time implementation and conclusion.
