| Abstract: | Solid wood flooring image acquisition and pre-processing is an important step on the floor level sorting based on computer vision;because a large amount of image data,the use of online sorting unable to meet the real-lime requirements of CPU proccssing method based on the software architecture. By utilizing the FPGA parallel processing capabilities and pipeline technology ,flexibilily and high processing speed of image acquisition and pre-processing systems for floor was designed.Design of FPGA-based parallel computing fast median filering algorithm,an cffective solution to the classical median filtering algorithm is relatively more oftem.Experimental results show thttt Ihe proposed algorithm is designed to significantly improve the speed of image prepocessing. |
