基于FPGA的視頻自適應(yīng)Sobel算法設(shè)計與實現(xiàn)

摘  要：該文首先對標準Sobel算法進行分析，然后針對算法在其他方向邊緣檢測效果不好和閾值需要人為設(shè)定等不足對算法進行改進和優(yōu)化。該設(shè)計采用FPGA作為硬件平臺，利用其并行處理能力，對Sobel算法進行硬件加速，使其能夠自適應(yīng)地處理不同分辨率和幀率的視頻流。

Abstract： This paper first analyzes the standard Sobel algorithm， and then improves and optimizes the algorithm to address the shortcomings of the algorithm such as poor edge detection performance in other directions and the need to manually set thresholds. This design uses FPGA as the hardware platform， and uses its parallel processing capabilities to hardware accelerate Sobel algorithm， making it able to adaptively process video streams with different resolutions and frame rates.

Keywords： Sobel algorithm; bilinear interpolation; FPGA; adaptive threshold; hardware acceleration
