一种基于区域水平的纹线距离估计方法
A fingerprint ridge distance estimation method at region level
【摘要】 突破了基于整幅图像或者基于分块图像进行纹线距离估计的传统思路,根据纹线方向一致性,自适应地将一幅指纹图像划分为若干个区域,在区域水平上实现了纹线距离估计。
【Abstract】 This paper breaks through conventional ideas that estimate ridge distance at a whole image of at block image,and brings out a new method at region level to estimate ridge distance according to the consistency of ridge directions.
