一种改进的双边滤波图像去噪算法
Improved bilateral filtering algorithm
摘要
Abstract
Similar weight of bilateral filtering is only controlled by σr , so the texture detail in smooth area or complex envi-ronment cannot be reserved well. Therefore, a developed bilateral filtering algorithm with adaptive fractional order differ-entiation is proposed. The amplitude-frequency nonlinear model is established through analyzing texture characters and computing frequency gradients/amplitude change based on bilateral filter algorithm, which automatically chooses fractional order v to create mask operator using fractional order differentiation. Experimental results show that the proposed algo-rithm has better performance in noise filtering while maintaining/enhancing texture details robustly.关键词
